Implementing Modified Cluster Head Selection in Existing TEEN Routing Protocol

The study of various protocols in wireless sensor networks shows that energy is the key concern in WSN due to the limited irreplaceable power sources of sensor nodes. The main reason for that is large amount of energy used in data transmission. Various researches take place to improve the energy efficiency and lifetime of WSN by developing routing algorithms. In this paper, Modified cluster head selection implemented in existing TEEN routing protocol to enhance the energy efficiency of the existing protocol in wireless sensor networks. A variable value of threshold energy is used for the nodes to aggregate data and transmit it to further nodes, which leads to increase the residual energy of each node and hence the performance. We evaluated the results after implementing the modified cluster head selection in existing TEEN routing protocol and observed that it performs better than existing TEEN routing protocol.
