EARP based cooperative MIMO for lifetime enhancement of WSN using game theory

Wireless sensor networks are affected by unbalance energy consumption due to the networks characterized by many-to-one multihop traffic pattern. The sensor networks lifetime is reduced due to channel fading and interference in WSN, a lot of energy are wasted due to uneven energy dissipation of node for different process. An energy-aware routing protocol (EARP) suitable for WSNs to provide uniform energy consumption in various phases of route discovery and maintenance. The multiple input multiple outputs (MIMO) scheme is used due to providing high diversity gain and spatial multiplexing. In this paper the EARP with MIMO used to conserve more energy. Simulation results of proposed cooperative MIMO (C-MIMO) show that great energy savings can be achieved and also prolongs the network lifetime.
