An Improved DEEHC to Extend Lifetime of WSN

Sensor networks consist of randomly deployed nodes that are powered by smaller batteries. The quantum and quality of information sensed by these nodes is of vital importance. Battery saving techniques or algorithms are need of the hour. One such technique is clustering of the nodes. This paper presents modification to existing DEEHC algorithm that builds multiple vertex disjoint paths from nodes to base station via cluster heads. The proposed modification (MDEEHC) improves the performance of the network as equated to DEEHC and FLDEEC by relaying the data of the child cluster heads using relay nodes. MDEEHC shows improvement in terms of throughput, packet delivery ratio, number of packet drops and remaining energy.
