摘要
自组网介质访问控制协议是影响自组网性能的重要因素。形式化地描述并分析了结合多信道和功率控制技术的自组网MAC协议性能特征。NS-2仿真实验表明,与没有功率控制的AODV相比较,在功率控制技术中合理的引入多信道技术,可有效的降低功率控制所引发的碰撞增加问题,增加节点和网络的生存时间。
Medium access control(MAC)protocol is one of the. most important factors which affect MANET's performance. Characteristics of power control MAC combined multiple channel in MANET are described and analyzed in formalization language. The NS-2 simulations revealed that introducing proper multi-channel technique into MANET can effectively decrease packets collision among nodes which transmit radio with different power, and prolong the life time of nodes and network in comparison with AODV that has no power control.
