A Wireless Sensor Network MAC Protocol based on Opportunistic Fairness Back-off Scheme
Shenghong Li · Communications technology · 2011
A Medium Access Control(MAC) protocol,based on a new back-off scheme,a modification of SMAC for wireless sensor network is proposed.Both throughput and channel state are taken into account and a new method for computing back-off time is introduced into this new scheme.The simulation result shows that the new method for computing back-off time could achieve good performance in both node fairness and network throughput.The method proposed here only needs a minor modification of SMAC protocol and is easy in implementation.
