A Residual Energy-Based Fairness Scheduling MAC Protocol for Wireless Sensor Networks

摘要

The Residual Energy-Based Fairness Scheduling MAC Protocol presented in this paper is aimed to solve the problems of how to ensure a balance energy consumption of WSN, how to reduce the collisions from interfering nodes in wireless sensor networks by introducing the fluid fair model into the wireless sensor network. We provide a conception of residual energy, and distributed energy fair scheduling MAC protocol for nodes to maintain a neighbor node's residual-energy queue so as to preserve the long-term balance energy consuming for every wireless sensor node and avoid the emerging of the network Island. The effectiveness of the protocol is validated through the simulation test to ensure the longest lifetime of WSN.
