Energy aware data collection in wireless sensor network using chain based PEGASIS

This paper proposes a variant approach for chain formation in the wireless sensor network which is a modified version of chain based PEGASIS protocol. It also proposes a different method for leader selection among the nodes in sensor network. This approach reduces average amount of energy consumed by the network and improves the overall network life time. In this paper, the process of forming chain is modified in order to obtain a chain with multiple degree nodes. This approach considers degree of connectivity and remaining energy of each node. Simulation of this approach is performed on Matlab which gives better result when calculated the average energy of the whole network in each round as compared to PEGASIS.
