Relay Assisted Cooperative Communication for Wireless Sensor Networks

In this proposed work, Cooperative Communication in Wireless Sensor Networks is analyzed.The Cooperative Communication helps in reliable information transfer consuming minimum energy and ensuring reduced error performance. Energy Efficiency and error performance are critical in the design of cooperation in a Wireless Sensor Network System as they decide node lifespan. In this paper, a 100×100 sq m farm area is considered for isolating crop disease. The information required for the crop disease is transferred to the remote destination in three ways Direct path, Singlehop and Multihop depending on the Channel State Information and Farm area.One of the above configuration is chosen based on the Bit error rate and energy efficiency. It is found that the Multihop has better energy efficiency compared to Singlehop and Directpath.
