An Improved Energy Efficient Chain Based Routing in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) consists of sensor nodes that are battery powered, these nodes are often deployed in remote areas and left unattended for long periods between battery charges. According to the studies, over sixty percent of energy is consumed during the transmission and reception process of the network. Due to the reason stated above, protocols and algorithms have been designed to manage energy, to make sure that the life span of the network is prolonged. This study proposes the improvement of the Energy Efficient Chain Based Network protocol (ECBSN). This protocol has challenges in a way it forms the chains using fixed number of nodes per chain instead of varying the number of nodes in a chain at different levels. This cause the chain furthest to the Base Station (BS) to die faster if it's Cluster Head (CH) is the chosen leader which has to relay all aggregated data to the sink just like in the Improved Energy Efficient Chain Based Network (IEBSN). We then propose the Improved Energy Efficient Chain Based Routing (IECBR) in WSNs. This study will consider varying the number of nodes at different levels, that is more nodes will be assigned to the chain closest to the BS and the further you are to the BS few nodes will be assigned. It will also consider the level of the energy and the distance of the node which is the CH to the BS. The simulation results showed a great improvement in the lifespan of the nodes in the network as compared to ECBSN.
