Abstract— In Wireless Sensor Network (WSNs), gather the
data by using mobile sinks has become popular. Reduce the
number of messages which is used for sink location
broadcasting, efficient energy data forwarding, become
accustomed to unknown earthly changes are achieved by a
protocol which is projected by a SinkTrail. The forecast of
mobile sinks’ location are done by using logical coordinate
system. When sensor nodes don’t have any data to send, at
that time they switch to sleep mode to save the energy and
to increase the network lifetime. And due to this reason
there is a chance of the involvement of nodes that are in
sleeping state between the path sources to the mobile sink
which is selected by the SinkTrail protocol. Before become
the fully functional and process the information, these
sleeping nodes can drop the some information. Due to this
reason, it is vital to wake-up the sleeping nodes on the path
earlier than the sender can start transferring of sensed data.
In this paper, on-demand wake-up scheduling algorithm is
projected which is used to activates sleeping node on the
path before data delivery. Here, in this work the multi-hop
communication in WSN also considers. By incorporating
wake-up scheduling algorithm to perk up the dependability
and improve the performance of on-demand data forwarding
extends the SinkTrail solution in our work. This projected
algorithm improves the quality of service of the network by
dishonesty of data or reducing the loss due to sleeping
nodes. The efficiency and the effectiveness projected
solution are proved by the evaluation results.

I. INTRODUCTION
In wireless sensor network (WSN) applications, incessant
monitoring is an important form. A large number of sensor
nodes are employed by a continuous monitoring for data
gathering and continuous sensing. In wireless sensor
network, every sensor node every so often senses and
creates a specific type of data. Furthermore, node reports
that data to one or several base station(s). In wireless sensor
network (WSNs) consist of a variety of applications that’s
why they have grow to be admired in various fields like
forest fire detection [1], habitat monitoring [2],
environmental science, home health care, military
surveillance. A wireless sensor network (WSNs) are
generally used for the low cost and long term monitoring
applications. While designing the sensor network protocols,
the minimization of energy consumption is a key challenge
concerned in wireless sensor network.
Existing research efforts demonstrate that
permitting sink mobility is more energy efficient approach
for data gathering [3] instead of instituting extended multi-
hop routes to the sink to report data. Wireless
communication capability used as a mobile sinks which is
equipped to achieve mobility, animals or vehicles. To
reduce energy consumption and data transmission paths, the
mobile sinks trail from one location to another location to
collect data from sensor nodes. Even idle listening by sensor
nodes consumes a significant amount of energy decreases
the lifetime of the node are proved by various studies done
on power consumption in WSN. Consequently, switch the
sensor node to sleep mode throughout idle times and wake it
up at periodical intervals to ensure presence of any data is an
effectual approach to conserve energy in WSN.
A. Existing Techniques Limitation
SinkTrail, a greedy data forwarding protocol which is self
adaptive to various application scenarios projected by a
Xinxin Liu et al. [4]. Mobile sinks move incessantly in the
field in comparatively low speed, and gather data on the fly
in SinkTrail. However, in wireless sensor network the
authors fail to consider sleep/wake approach used to
conserve energy.
B. Our Observations
The sleep/wake scheduling provides perfect synchronization
is assumed by existing research efforts. The impact of
synchronization error is non-negligible are proved by the
authors [5]. We experiential that even though existing
systems try achieving exact synchronization between wake-
up of sensor nodes for transmission/reception of data, there
still lives arbitrary synchronization error due to the non
deterministic factors in the system.
C. Our Solution
In wireless sensor network (WSN), on-demand wake up
scheduling for proactive data reporting are projected in this
paper. It is relies on the SinkTrail protocol to retrieve the
shortest path to the mobile sink. The projected approach
sends a wake-up message to all nodes in the path rather than
directly starting data transmission, once the path is obtained.
This is useful for the nodes which are in sleeping mode to
switch to an active working state. As a result, it perks up the
dependability of the system by reducing the synchronization
errors and data loss. The source node starts data
transmission to the mobile sink upon the acknowledgement
from nodes in the route. The efficiency and effectiveness of
the projected solution are proved evaluation results.

D. Our Contributions
In wireless sensor network, for proactive data reporting on-
demand wake-up scheduling projected in this paper. Our
contributions in this paper are
(1) To extend SinkTrail protocol by projecting a wake-
up scheduling technique.
(2) This work also discovers the impacts of several
intend strictures of the projected solution.
(3) Projected solution and conducted extensive
simulation based experiments implemented here.
The efficiency and effectiveness of the projected
solution are proved evaluation results.
In this paper we discuss about the related work in
section II, proposed method in section III where we design
our solution, mathematical model, algorithms. In section IV
we proved the simulation result with graph and at last
conclusion in section V.
II. RELATED WORK
Due to the arbitrary movement of the nodes and multi-hop
routing, a lot of control signal overhead is introduce for
route discovery in wireless sensor networks (WSN). It is
intolerable in energy-constrained wireless sensor networks.
Constantly changing topology and energy constraints are
served by the sensor nodes. Sensor nodes frequently switch
themselves into a sleep state and occasionally wake-up to
check, if there is data for them to send to the sink, to perk up
the network lifetime in WSN. In order to reduce the energy
consumption and design sleep/wake-up scheduling
algorithms for a wireless sensor network (WSN) wide
research efforts have been taken.
A. Sleep/Wake Scheduling for Sensor Networks
MAC based protocols can be classified as contention based
or TDMA in wireless sensor networks. Waste of energy
occurs due to collisions, idle listening and overhearing in
contention based MACs. Therefore to avoid eavesdropping
and save energy of nodes in WSN, research efforts [6], [7]
projected mechanisms.
B. Clustering
A hierarchical clustering techniques developed by a class of
research efforts. To manage large wireless sensor networks,
clustering is an energy efficient and scalable method. Nodes
which are close to each other and within a geographical
region are grouped together to form a cluster. Base station
selects one node from each cluster as a cluster head that is
CH which is organize with the nodes within the cluster. As
well CH is responsible for communication between the
cluster and the BS or other cluster heads. This grouping
process can be recursively applied on other clusters, to build
a cluster hierarchy.
C. Mobile Agent Scheduling
Mobile Element Scheduling (MES) algorithms [8], [9], [10],
[11], [12] focus by the class research efforts. Mobile sink
mobility controlled and prediction of the moving path of the
mobile sink is considered by this algorithm.
 Summary: The two wrong assumptions are making
by the most existing sleep/wake scheduling
schemes. First, nearly perfect synchronization can
be provided by the underlying synchronization
protocol. Second is clock disagreement is
negligible. While designing a solution for wireless
sensor network, it is critical to integrate sleep/wake
scheduling. To improve the performance and perk
up the dependability of on-demand data forwarding
by incorporating wake-up scheduling algorithm
expanded the sink solution in this paper.
III. PROPOSED METHOD
A. Mathematical Model
In this paper, the problem addressed formulated .
Here, for any given network of N nodes like data collected
D in the sink is maximum. Thus if di is data sent by node ni
then the total data D collected by the sink in time t is given
as:
D = ∑ ∑ it
Where,
N = total number of nodes.
ni = the ith
sensor node, where I = 1,2,3,…..n
S = the mobile sink
msg.seqN = the message sequence number
mag.hopC = the message hop count
Ei = the initial energy of node ni
(1) Proposed System Algorithm
The proposed system algorithm is given below,
Step 1: Using the SinkTrail protocol, perform the logical
space coordinate space construction.
Step 2: Using the SinkTrail protocol, nodes in the network
start sending data to the mobile sink.
Step 3: Let K be the time for which we wish to run the
protocol.
Step 4: Let n1s, n2s, n3s …nms be the total number of m
nodes, who choose sleep mode as they don’t have to send
data.
Step 5: Let nsrc be the source node that needs to send the
data sink. It gets the path to the sink node S using the
SinkTrail protocol.
Step 6: The list of sleeping nodes which are in its path to
sink is created by the nsrc.
Step 7: For these sleeping nodes, wake-up request generated
by the nsrc.
Step 8: nsrc starts data transfer, after a response from all
sleeping nodes. Or else, it initiates a request to the sink to
establish an alternative path.
IV. SIMULATION RESULT
It performed on several arbitrary networks created by
distributing nodes in random order, to evaluate the projected
algorithm. To evaluate situation-specific performance in
networks is the aim of this test. Custom simulator software
was developed in java to run simulation and perform
assessment tests.

Fig.5: Network Size with wake up and without wake up.
The overall system performance is exaggerated by
the number of mobile sinks. Several logical coordinate
spaces are building concurrently and data packets are
forwarded to the destination orientation via the shortest path
in any coordinate space. Heavier weights for trail message
broadcasting and routing information maintenance imposed
by increasing the number of mobile sinks.
Here we shows the graph, in figure 1 illustrate the
energy utilization of each node with wake-up algorithm.
Figure 2 illustrate the energy utilization of each node
without wake-up algorithm. By comparing two graphs we
see that without wake-up algorithm use high energy. That
means using wake-up algorithm we save the energy
utilization and increase the lifetime of network. In figure 3
network size verses energy utilization where we see the
wake-up algorithm use less energy as compared to the
without wakeup. Hence this evaluation shows that our

projected solution save the energy and increase the lifetime
of network.
V. CONCLUSION
Nodes generally switch to sleeping mode to save the limited
amount of available energy in sensor nodes, in wireless
sensor network (WSN). Too periodically activation of the
node is done by using sleep time interval. An on-demand
wake-up scheduling algorithm which is used to activate the
sleeping node on the path before data delivery is projected
in this paper. We consider multi-hop communication in
WSN, in this work. To improve the dependability of on-
demand data forwarding and to enhance the performance,
our work extends the SinkTrail solution by incorporating
wake-up scheduling algorithm. By reducing corruption or
loss of data due to sleeping nodes, the projected algorithm
improves the quality of the service of the network. The
efficiency and effectiveness of the projected solution are
proved evaluation results.
