In certain situation even if the channel is reliable, the communication may not be so. In this paper, we first show that with simple modification, 1-bit compressive sensing can also been used for the data gathering . In order to minimize the total communication overhead and also to avoid the introduction of new vulnerabilities, the joining little help is available for the WSN application developer who must answer the question “what is the optimal cluster?” We define the optimal cluster as the one sized such that routing data from the cluster members to cluster heads and subsequently to base stations incurs the minimal communication overhead. The wireless sensors in the sensing field periodically take measurements from The Wireless sensor network consists of hundreds or thousands of low powered sensor nodes that have ability to communicate either directly to the base The EEEMR Protocol is slightly improves the QoS Parameters like throughput, delay, overhead and packet delivery ratio when compared to DSDV, DSR and AODV.
