移动Ad Hoc网络中一种有效多址协议的性能仿真
Simulation Study on an Efficient Multiple Access Protocol for Mobile Ad Hoc Networks
【摘要】 基于有效竞争预约接入、无冲突轮询传输的思想,本文提出了支持节点移动性和多跳网络结构的依据用户妥善安排的多址接入(UPMA)协议,并使用网络仿真工具OPNET评估了它的多址性能。仿真结果表明,该协议显著提高了多跳网络的业务传输效率。
【Abstract】 Based on the concept of contention reservation and polling transmission,a user-dependent perfect-scheduling multiple access(UPMA) protocol for supporting node mobility and multihop architecture in wireless multihop mobile ad hoc networks is described.Then its performance is evaluated by OPNET.Simulation results show that the proposed protocol can greatly improve end-to-end transmission efficiency of traffic over multihop architecture.
