Energy Efficient Relay based Protocol for WSN with uniform Clustering

Some of the vital issues that need to be considered in wireless sensor network (WSN) based applications are improving the network lifetime without replacing the batteries of node and elimination of energy imbalanced hotspots in the network. Many protocols are proposed for energy efficient cluster based sensor network. In this project, Energy efficient relay based protocol is proposed for wireless sensor network where cluster heads are evenly distributed. The proposed protocol is combined with the Multi Input Single Output (MISO) technique which is extended for dual hop wireless sensor network to improve the network life time. Further, the selection of relay nodes for cluster heads is designed to avoid unexpected partitioning. We also found the efficient relay positions for dual hop transmission. We compare the performance of this proposed protocol with the existing standard protocol Low Energy Adaptive Cluster Head (LEACH).
