A Scalable Energy Efficient and Delay Bounded Data Gathering Framework for Large Scale Sensor Network

This work details a new class of energy efficient and delay bounded data gathering framework viz. generalized intra cluster chaining (GICC) framework for large scale wireless sensor network. The framework extracts the advantages of both purely cluster based and purely chain based data gathering schemes for wireless sensor network without compromising with their drawbacks. Detailed analysis and simulation results reveals GICC increases the performance of any purely cluster based protocols by 60-70% and also utilizing only localized information increases the network lifetime comparable with optimal results. GICC framework also tends to decrease information loss due to in-network aggregation, delays in in-network packet forwarding and is practically applicable to all kinds of wireless sensor network.
