ENERGY EFFICIENT DATA COLLECTION IN WIRELESS SENSOR NETWORK

Abstract

Wireless Sensor Network has wide range of applications in the field of networks. The sink nodes need to communicate effectively with other sensor nodes, for effective communication. The facts such as cluster size, energy and lifetime of the nodes should be considered to make the communication effective. While transmitting, the nodes are grouped in clusters with one head per cluster. The cluster, nearer to the sink nodes may run out of energy due to continuous utilization. So an intermediate node for communication is used, called as AGM node. The sensor nodes in the clusters, first send the information to their cluster head (chosen on the basis higher residual energy), the cluster head in turn sends the information to the AGM node whereas the AGM transmits it to the respective sensor node and vice versa. Selection of AGM among many nodes and the entire process is carried out on the basis of the maneuver algorithm, which has 6 phases like compact clustering, AGM selection, Interclustering, Load balancing and data distribution, Communication and replenishment and Reconcile algorithm. In this process the CH transmits data after eliminating redundancy in it. In case of massive damage, Reconcile algorithm is used for the efficient usage of available AGM nodes to regain from the relapsed network.
