Abstract:

Cluster based routing have been successful to enhance the lifetime of the sensor network and also reduced the overall cost of communication. Conventional clustering protocols classifies the sensor network into a number of clusters and every cluster has a cluster head. The sensor nodes routinely sends their received data to their respective CHs and the CHs functions to aggregate data and then transmit this accumulated data to the BS. Thus CHs drains energy more quickly than other nodes in the clusters, reducing the lifetime of the networks. Several clustering protocols like LEACH rotates the cluster heads in order to maintain the energy of all the nodes. But it suffers from clustering overhead. Static clustering avoids the overhead of dynamic clustering. But these clusters do not allow new nodes to join the clusters and thus the nodes performance is not affected by nodes dying. To avoid this chain based routing protocols were proposed. PEGASIS is a chain based protocol but it suffers from transmission delays due to long links. In order to avoid this we proposed Energy Efficient Clustered Chain Based Power tracking Routing Protocol (EECCPTR) For Wireless Sensor Networks. The main objective of this protocol is to enhance the lifetime of the network and reduce the communication cost by homogeneously distributing the energy load among associated  sensor nodes.
