چکیده
Wireless Sensor Networks (WSNs) is an interesting topic to the researchers because of its various applications. The applications are health monitoring and environmental monitoring, Industrial Process Monitoring, Target detection, Target tracking, Energy Efficiency, Disaster Management and Military Security Systems. The wireless medium requires highly optimized medium Access Protocols to avoid interferences. Limited resources have driven the research towards energy consumption of MAC functionalities. Two Medium Access Control (MAC) protocol performances are analyzed by using the MAC layer frame work for wireless sensor networks. In this paper an energy efficient analysis of S-MAC and HMAC protocols for wireless sensor networks is proposed with spatial correlation concept. Two MAC protocols such as Sensor MAC (S-MAC) and Hybrid MAC (H-MAC) protocols are proposed to analyze the performance of Wireless Sensor Network using four different Parameters such as End to End delay, Packet Delivery Ratio, Packet Drop Rate and Energy Consumption. Performance analysis is carried out by using the simulation tool NS2.
