Abstract: In order to solve the problem of constituting large scale mobile Ad Hoc network in some special environment. A new model of mobile multi-protocol fusion gateway is proposed. The gateway transmits data among Ethernet, Wireless Local Area Network(WLAN) and multi-layer Ad Hoc network by integrating several routing protocols in IP layer. Based on the different function in Ad Hoc, a new hybrid routing protocol is proposed to decrease the routing finding converging time and increase the efficiency of network self-adaption. The gateway is modeled by OPNET and the network topology which includes gateway is simulated. Results show that the gateway meets the requirement of constituting heterogeneous network in mobile environment quickly, stably and flexibly and it performs well in exchanging and transmitting data packages in heterogeneous network and ensures the demand of Quality of Service(QoS) which running over heterogeneous network in mobile environment and reduces the converging time of routing protocol simultaneously.

摘要: 为在特殊环境下快速组建大规模移动自组网,提出一种移动多协议融合网关,该网关具有互通以太网、无线局域网、多层级Ad Hoc网络的能力。采用在网关IP层实现多种路由协议转换的方案,结合网关与终端的特点,对网关级Ad Hoc网络与终端级Ad Hoc网络使用不同的路由发现机制,以保障路由收敛时间最少,提高网络的自适应速率。网关采用OPNET软件建模并仿真实际组网拓扑结构,结果表明,移动多协议网关能满足移动环境下组建快速、稳定、灵活的异构网络的要求,并实现异构网络之间数据的交换和无缝转发,满足异构网络业务的服务质量需求,同时减少路由收敛时间。
