【摘要】 SIP是未来通信网络的主要信令协议之一,但Ad Hoc网络本身没有基础设施.让Ad Hoc网络中的节点本身承担SIP Server的功能,以AODV和ZRP 2种类型不同的路由协议为基础来研究SIP在Ad Hoc网络中的应用.NS2模拟结果表明,就SIP的呼叫建立延迟而言,在静态多跳Ad Hoc网络中,SIP-ZRP方法相对较好;在节点随机移动的情况下,SIP-AODV方法较好;在这2种条件下,SIP-ZRP有较低的路由分组开销、较高的呼叫建立成功率.更多还原

【Abstract】 SIP is one of the most important signal protocols in future communication network.A method that the nodes themselves act as the functions of SIP Server was presented because of lack of infrastructures in Ad Hoc network,the application based on two different routing protocols: AODV and ZRP were discussed;Simulation results using NS2 showed that SIP-ZRP performs better for static multihop Ad Hoc network than SIP-AODV in terms of the latency in SIP session setup;SIP-AODV performs better in networks with random node mobility.SIP-ZRP has lower routing overheads and higher call setup success rate.更多还原
