Energy efficient cluster head selection technique for homogeneous wireless sensor networks

Wireless sensor networks are very suitable for remote sensing and monitoring tasks. Sensor nodes being battery operated devices and other limited resources present many challenges for protocols in WSNs. Researches are being continuously conducted with the purpose of combating these issues. Clustering in WSNs aim to distribute the energy load of the nodes by assigning some aggregator nodes or cluster heads. This paper presents a new criteria for CH selection which uses concepts of node density and residual energy. The purpose is to have a load balance to prolong network life.
