A Novel Energy Efficient Mobility Aware MAC Protocol for Wireless Sensor Networks

Dealing with mobility at the link layer in an efficient and effective way is a formidable challenge in Wireless Sensor Networks due to recent boom in mobile applications and complex network scenarios. Most of the current MAC protocols proposed for WSNs generally focus on stationary network and usually provide feeble network performance in situations where mobile nodes are involved. Many MAC protocols are proposed and techniques are developed to support mobility but they undergo massive energy consumption and latency problems due to frequent connection setup and breakup. In this paper, we propose a new energy efficient mobility aware based MAC protocol (EEMA-MAC), which work efficiently in both stationary and mobile scenarios with less energy consumption. In this protocol the member nodes have sleep and awake time same like existing S-MAC protocol but it expedite the connection setup and efficiency as Cluster Head (CH) has extended wake up time and less sleep time. Simulation results show that this mechanism is effective to avoid frequent disconnection of nodes and performs well in terms of energy consumption, throughput and packet loss as compared with existing protocols, such as S-MAC and MS-MAC.
