The document presents a three-layer framework called Load Balanced Clustering with MIMO (LBC-MIMO) for efficient mobile data collection in wireless sensor networks, aiming for improved scalability, energy efficiency, and reduced data collection latency. The proposed system organizes sensors into clusters and utilizes multiple sensor nodes for concurrent data uploading to a mobile collector, optimizing energy consumption.

- 3. Abstract • A three-layer framework is proposed for mobile data collection in wireless sensor networks which includes the sensor layer, cluster head layer, and mobile collector (called SenCar) layer. • The objective is good scalability, long network lifetime and low data collection latency. • Sensor layer a distributed load balanced clustering (LBC) algorithm for sensors to self-organize themselves into clusters. • Multiple sensor nodes in each cluster to balance the work load and facilitate multiple data uploading. • Cluster head layer the inter-cluster transmission range is carefully chosen to guarantee the connectivity among the clusters. • cluster head information is forwarded to SenCar for its moving trajectory planning.
- 4. Abstract (Conti…) • Sencar layer equipped with two cluster heads in these two cluster heads to simultaneously upload data to sencar in each time by utilizing (MU-MIMO) technique. • The SenCar is optimized to fully utilize multi data uploading capability and properly selecting polling points in each cluster. • By visiting each selected polling point, SenCar can efficiently gather data from cluster heads and transport the data to the static data sink. • The effectiveness of the proposed LBC-MIMO scheme 50% energy saving per node and 60% energy saving on cluster.
- 5. Existing System • Several approaches have been proposed for efficient data collection Based on these work, we divide into three categories. • First enhanced relay routing in which data are relayed among some other sensors. • Second sensors into clusters and allows cluster heads to take the responsibility for forwarding data to the data sink. • Clustering is useful for local data aggregation since it can reduce the collisions and balance load among sensors. • Third to make use of mobile collectors to take the burden of data routing from sensors.
- 6. Disadvantages • Relay routing schemes, minimizing energy consumption on the forwarding path does not necessarily prolong network lifetime, • Cluster-based schemes, cluster heads will inevitably consume much more energy • Mobile collectors may alleviate non-uniform energy consumption, it may result in unsatisfactory data collection latency.
- 7. Proposed System • A three-layer mobile data collection framework, named Load Balanced Clustering and MIMO uploading (LBC-MIMO). • The main motivation is to utilize distributed clustering and energy saving and uniform energy consumption and to exploit MU-MIMO technique. • First, a distributed algorithm to organize sensors into clusters, where each cluster has multiple sensor nodes. • Second, multiple sensor nodes within a cluster can collaborate with each other to perform energy efficient inter-cluster transmissions. • Third, Sencar with two cluster heads and allow concurrent upload data from two cluster heads by using MU-MIMO communication and collect data.

- 9. Advantages • Clustering techniques balances the load of intra-cluster aggregation and enables multi data uploading between multiple cluster heads • Hierarchical schemes cluster heads do not relay data packets from other clusters which effectively alleviates the burden of each cluster head. • The MUMIMO technique which enables multi data uploading to shorten data transmission latency. • We coordinate the SenCar multiple data uploading and data collection tour with both short moving trajectory and short data uploading time.
