An analysis of H-MAC, HSMAC and H-MAC based AOMDV for wireless sensor networks to achieve energy efficiency using spatial correlation concept

The energy performance of Wireless Sensor Networks (WSNs) is more significant only when the design of Medium Access Control (MAC) Protocols is completed. The Proposed work deals with energy efficiency analysis of WSNs. To achieve energy efficiency in WSNs three different hybrid medium access control based protocols are preferred. The three protocols are Hybrid Medium Access Control (H-MAC), Hybrid Sensor Medium Access Control (HSMAC), Hybrid Medium Access Control (H-MAC) based Adhoc on Demand Multipath Distance Vector (AOMDV). Among the protocols, H-MAC based AOMDV yields better result. The Spatial Correlation method with Routing Concept is adapted for H-MAC oriented protocols. From the results, the energy efficiency value of H-MAC based AOMDV provides 13.9% higher value than that of H-MAC and HSMAC protocols. Along with energy efficiency the QoS issues such as End to End delay, Packet delivery ratio, Throughput are also considered. The parameter based analysis proves that H-MAC based AOMDV is the best protocol to analyze the energy efficiency in WSNs.
