Mobility-Aware Hybrid Medium Access Control Protocol for Wireless Sensor Network (WSN)

Efficient MAC protocol has been paramount importance for improving the performance of WSN. In this paper, Boarder Node Medium Access Control (BN-MAC) mobility aware hybrid protocol is introduced for WSN. BNMAC controls overhearing, idle listening and congestion problem to save energy. BN-MAC mechanism is based on novel semi synchronous low duty cycle that takes less time for accessing channel and faster delivery of data. The objective of introducing BN-MAC protocol is to support four application areas: monitoring and behavioral areas, controlling natural disasters, tracking and handling home automation devices and human-centric application areas. These application areas need contention free mobility support features with high delivery of data. BN-MAC also provides mobility support for these applications. Evaluation of BN-MAC is conducted using network simulator-2 (ns2) then compared with known low power listening (LPL) and X-MAC low duty cycles MAC protocols. Additionally, we have also compared BN-MAC with MAC hybrid protocols: Zebra medium access control) (Z-MAC), advertisement-based MAC (A-MAC), Speck-MAC, Adaptive Duty Cycle SMAC (ADCSMAC), low power real time medium access control (LPRMAC) protocol. On basis of initial Simulation results, we demonstrates that BN-MAC protocol saves extra 18% to 45% energy resources as compared with other MAC protocols.
