Stable Routing Algorithm for Mobile Ad Hoc Network

Mobile Ad Hoc network is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of pre-established network infrastructure. With a great deal of different applications increasing, it needs to provide stable communication for such network. In this paper, a new routing algorithm is proposed which can dynamically estimate delay variety and calculate link stability factor. In the route discovery phase, it finds paths meeting delay requirement with greatest stable link. In the route maintenance phase, it effectively keeps monitoring network topology changes through delay prediction and performs rerouting in time. Furthermore, some enhancement strategies are adopted to control route acquisition latency and improve transmission quality. Simulation results show that it can meet with the delay requirement while decrease the routing cost. Comparing with other conventional routing algorithms, it can achieve higher packet delivery rate especially in rigorous network environment.
