Ad Hoc网络路由协议的仿真分析

Ad Hoc Network无线局域网络又称自组网络，是将移动性扩展到无线领域中的自治系统，它有自己特定的路由选择协议。Ad Hoc络广泛应用于军事、民用通讯领域和自然灾害发生时的营救场合。利用OPNET软件仿真并分析Ad Hoc网络典型的DSR、TORA两种按需路由协议；在网络负载低、高情况下，从业务量、网络时延和丢包率几个方面进行对比分析论证，得出了两种路由协议在不同场景下的性能特点。

Simulation Analysis of Routing Protocol in Ad Hoc Network

Ad Hoc wireless network was also called Mobile Ad Hoc Networks.It was an autonomous system in which mobile quality expands to wireless domain and it has its own specific intra-domain routing protocol.It is widely used in military communications,civil communications,and on occasions when rescue is needed for natural disasters.This paper analyzed ADHOC network routing protocols after conception of routing protocol was introduced.Two-on-demand typical routing(DSR and TORA) protocol of AD HOC network was analyzed using the OPNET simulation software.On the cases of the low or high network load,we got the performance characteristics of the two routing protocols under different scenes from several aspects of demonstration and analysis among the quantity of business,the network delay and the rate of packet loss.
