Low Duty Cycle, Energy-Efficient and Mobility-Based Boarder Node-MAC Hybrid Protocol for Wireless Sensor Networks

摘要

The need for an efficient medium access control (MAC) protocol is extremely important with the emergence of wireless sensor networks (WSNs). The MAC protocol has increasingly been significant in advancing the performance of WSNs. In this paper, a low duty cycle, energy-efficient and mobility-based Boarder Node Medium Access Control (BN-MAC) hybrid protocol is introduced for WSNs that controls overhearing, idle listening and congestion issues by preserving energy over WSNs. BN-MAC leverages the features of contention and schedule-based MAC protocols. The contention encompasses the novel semi-synchronous approach that helps obtain faster access to the medium. The schedule-based part helps reduce the collision and overhearing problems.
