Mobile Ad Hoc网络与Internet互联的综合网关发现方法

A Hybrid Approach to Internet Connectivity for Mobile Ad Hoc Networks

大量基于adhoc网络的移动应用得以开展以及被认可的一大挑战就在于其能否提供足够好Internet连接,本文实现了一种MobileAdHoc网络与Internet互联时的综合网关发现方法,由于综合了主动与被动网关发现方法的优点,同时允许中间移动节点解析全局连接信息并在必要的时候以之回复请求节点,因此在合理的开销下改善了移动节点多跳访问Internet的性能,用NS2进行的仿真结果说明了综合方法的有效性。

The biggest challenge to the deployment and acceptance of mobile applications based on ad hoc networking is the need for better Internet connectivity. We present a hybrid scheme that uses techniques such as TTL scoping of agent advertisements, eavesdropping and caching agent advertisements to combine the advantages of proactive and reactive approaches to providing Internet connectivity to ad hoc networking. Simulation results with NS2 shows that our approach achieves excellent connectivity while keeping overhead costs low.
