摘要:

针对基于位置的容迟容断网络(DTN)路由算法进行深入研究,提出一种适用于三维部署环境的基于位置的功率感知路由算法(3DPLRP),该算法利用节点三维位置信息寻路,大大降低了网络开销,此外因功率感知机制的引入延长了网络生命周期. 在不同网络环境下与Epidemic、PREP路由算法进行了比较,仿真实验结果表明,3DPLRP在节点移动速度不高的情况下消息投递率和端到端时延等性能均要优于其他路由算法.

Abstract:

The location-based delay tolerant networks (DTN) routing protocol is described, and a new three-dimensional power-aware location-based routing protocol (3DPLRP) is presented. 3DPLRP uses 3D location information of the nodes to decide the route will reduce the overhead of DTNs and introduces a power-aware scheme to extend the network lifetime. Compared with epidemic protocol and priority routing epidemic protocol (PREP) when considering their performance with different network environments, simulation is made and shown that the new one outperforms other two protocols in packet delivery ratio and end-to-end delay with slower moving speed of nodes.

Key words: delay tolerant network, three-dimensional, location-based, power-aware
