延迟容忍网络中移动模型对路由算法的影响
Impacts of Mobility Model on DTN Routing Algorithm
摘要
Abstract
DTN ( Delay Tolerant Network) is a new type of mobile Ad Hoc network. Due to its high bit-error rate,long delay and dy-namic topology,there is barely stable end-to-end path in those networks. Routing algorithm is the most abundant area of DTN and many representative researches have been achieved. The mobility model controls the node movement pattern,determining the direction,speed and the rest time in DTNs. However,researchers usually tend to evaluate their new routing protocols under single mobility model,ignoring the performance under other models. In this paper,focus on assessing the impact of mobility model on some distinguish routing protocols in terms of delivery probability,average latency and overhead ratio. Use the ONE to simulate the scenario where nodes move in certain ar-ea in Nanjing. The line charts generated show the performance of the routing algorithm under different mobility models. The simulation shows that the mobility has a great impact on the routing algorithm.关键词
