Cooperative communication enabled wireless sensor network for monitoring green house

The paper presents cooperative communication based wireless sensor network for monitoring Green house related parameters such as Temperature, humidity and Carbon-di-oxide. The system is demonstrated by using network simulator NS2 with increased network capacity to suit large geo graphical areas. The comparison results show that cooperative transmission provides better performance than non-cooperative transmission in various aspects, such as packet loss, packet delivery ratio (PDR), network capacity and throughput. It is observed that the energy efficient and successful transmission occurred within transmission range and better link quality. Further, the results proved that the transmission range increases as when throughput and packet delivery ratio are decreasing.
