摘要: 基于地理位置信息的路由协议具有很好的可扩展性。然而,当源节点和目的节点之间存在洞时,该类路由协议可能遇到局部最优的问题。针对此问题,提出了一种基于洞椭圆化的避洞路由协议。该协议通过把洞规则化为一个椭圆,并把洞的信息向外局部广播,从而有效地解决了该问题。模拟结果表明该路由协议具有路由延迟小、路径短等特点。

Abstract: The geographic routing protocols have the good scalability.However,when there are some voids between a source node and a destination node,the geographic routing protocols may meet the local optimum problem.Regarding the problem,this paper proposes a routing protocol with hole-bypassing based on hole-reshaping with ellipse(RPHE) in the large-scale Mobile Ad-hoc NETworks(MANETs).It effectively solves this problem by regularizing the holes with ellipse and by locally broadcasting the information of holes outside.Simulation studies show that the proposed protocol can get low routing delay and short routing path.

Key words: cluster, delay, grid, Mobile Ad-hoc Networks(MANETs)
