EECHEP: Heterojen sensör ağların ömrünü uzatmak için enerji verimli küme başı seçim protokolü.

Wireless Sensor Networks consist of a number of low cost, small sensor nodes powered by energy constrained batteries. Due to limited power, memory, and processing capacities of sensor nodes, it is essential to find new methods which improves energy consumption of the nodes and prolongs the lifetime of the network. Cluster head election among sensor nodes has an important role in wireless sensor networks to boost efficiency and lifetime of the network. In this study, a cluster head election method has been proposed and evaluated for heterogeneous wireless sensor networks, which extends the lifetime of the network. Simulation results reveal that the proposed cluster head election method offers a better performance than the SEP and LEACH protocols in terms of network lifetime and is able to provide throughput for a longer period of time. It is found that EECHEP provides efficient use of sensor energy and helps increase the number of surviving cluster head nodes that report to the base station. [ABSTRACT FROM AUTHOR]
