Ubiquitous Networking
Next Generation Service Platform

Users expectation towards
Next Generation
 Users expectation toward the next generation
service is not just to provide a large bandwidth.
 They would rather expect to maintain or enhance
their overall living environment, such as safety,
security, amenity and feeling ease with the
surrounding environment or within their community .
 They are not aware which communication
method they use .

Introduction to Ubiquitous network
Ubiquitous network is a context-aware
network of computing devices which are
connected at any place, anytime and with
any object
Ubiquitous network allows all users to access
and exchange information of any kind freely
at anytime, from anywhere, and from any
appliance through the use of broadband and
mobile access.
Combines optical communication, mobile
and consumer electronics into one network

What is Ubiquitous Networking ?
 Ubiquitous : Omnipresence
 Computing Everywhere
 Content Everywhere
 Connectivity Everywhere
 Seamless Connection and Service
 Location, Context & Preference-Aware Service

The role of ubiquitous network
The role of ubiquitous network should seek for fulfilling
such user needs in corporation with use terminal and
service platform.
Keyword is “context awareness” for a user.
Context means user’s general situation such as user’s
location, user’s access status, etc.
By always keeping aware of user’s context, a system
can offer the best service that he/she wants.

Applications Of Ubiquitous Networking
Use of Ubi-net in Household

Applications Of Ubiquitous Networking
Use of Ubi-net in GPS car tracking system

Background and assumptions
 Third generation cellular system is becoming
dominant and person-to-person call is mostly made by
cellular.
 Fixed broadband services will come into home
environment widely. Users will enjoy broadband access
both at office and home.
 Not only person-to-person communications, but other
communications style such as machine-to-machine
communications are gradually becoming popular.

Enablers
9
The following items are several possible enablers for
ubiquitous networking paradigm;
Advent of high-end mobiles which support 3G capability,
location, middleware environment, sensors, etc.
RFID technology with which man-to-environment
interactions much easier.
Ontology which deals with objects on the Web more
semantic way than ever.

Challenges in Ubiquitous Network
Management
The main challenges in ubiquitous network management are :
 Seamless connectivity
 Context awareness
 Resource management
 Device management

Always-on connectivity
Network Interface Management
Interface co-existence
Challenges in Seamless
Connectivity

Challenges in context awareness
Management
 Filtering
 Context – composition
 Adaptation
 Discovery of context
 Storage of context
 Access control on context

Challenges in Resource
Management
 Resource Dissemination: Information about
machine resources
 Resource Discovery :Mechanism by which
applications find resource information
 Scheduling Resources: Grids (Large scale
network computing system) decide which
resources are assigned to which jobs

Challenges in Device
Management:
Device Identification
Device adaptability
Device Tracking

Flexible service platform is the key
From the ubiquitous service point of view, an
ubiquitous network should have:
Flexible service platform execution
environment with common API,
Super high performance switching and
routing capability,
Broadband service capability,
Relevant adaptive routing mechanism.
