Maximizing Lifetime of Homogeneous Wireless Sensor Network through Energy Efficient Clustering Method

The main purpose of this paper is to develop a mechanism to increase the
lifetime of homogeneous sensor nodes by controlling long distance
communication, energy balancing and efficient delivery of information. Energy
efficiency is a very important issue for sensor nodes which affects the lifetime of
sensor networks. To achieve energy balancing and maximizing network lifetime
we divided the whole network into different clusters. In cluster based architecture,
the role of aggregator node is very crucial because of extra processing and long
range communication. Once the aggregator node becomes non functional, it
affects the whole cluster. We introduce a candidate cluster head node on the
basis of node density. We introduce a modified cluster based model by using
special nodes called server nodes (SN) that is powerful in term of resources.
These server nodes are responsible for transmitting the data from cluster head to
the base station. Our proposed algorithm for cluster head selection based on
residual energy, distance, reliability and degree of mobility. The proposed
architecture is more scalable and proposed algorithm is robustness against
even/uneven node deployment.
