  • 摘要:The use of wireless sensor networks is increasing day by day and at the same time, it faces the problem of energy constraints in terms of limited battery lifetime. In this paper, we propose an energy efficient algorithm in which network is divided into five sectors with an equal angle for maintaining uniformity of cluster heads. This algorithm is improved EELEACHMIMO algorithm in which data from the sensor nodes is transmitted through shortest path by nearest neighbor algorithm in multihop fashion and results in reduction of energy consumption in the network. The residual energy and the location of each node from sink are considered for the selection of cluster head and cooperative node for MIMO system. The simulation results show that the proposed algorithm enhances the energy efficiency and the lifetime of the network.
