一种适用于低速无线传感器网络的LR-MAC机制研究
Study on low-rate wireless sensor network LR-MAC mechanism
摘要
Abstract
Aiming at the problem that the increasing of the node in the wireless sensor networks may cause the lower saturation throughput and the higher packet collision. A novel channel access control mechanism for WSN, i. e. Lowe-rate MAC (LR-MAC) was proposed that the site firstly backoff for a moment after the site successfully send the data. The simulation results demonstrated that when the network size varies, LR-MAC performs much better than the L-MAC does.关键词
