Study on Co-operative Communication for Energy Efficient Routing in Wireless Sensor Network

Wireless Sensor Network (WSN) is a network of various nodes, which get connected with each other whenever they are deployed. The communication among nodes has been one of the major factors for the draining the energy of nodes. That is the reason, routing between sensor nodes becomes significant. In this paper, the one of the modes of routing is studied which incorporates co-operative communication among sensor nodes. The co-operative communication forms virtual MIMO (Multi Input Multi Output) structure which helps in enhancing the reliability and network lifetime of WSN. This paper contributes the summarizing the significant research work being done in the routing protocols following co-operative communication in WSN.
