物联网中一种面向聚集点的机会路由算法

物联网中感知设备可以随身携带,具有明显的社会属性.在设计转发策略的时候,需要考虑感知设备的社会属性对路由算法性能的影响.针对人们在日常生活、工作当中展现出的群聚行为,提出了一种面向聚集点的机会路由算法.该算法结合传统的多备份路由机制以及直接等待传输策略,通过在聚集区域内放置一个静态节点来辅助移动节点进行数据转发,解决移动网元之间以及移动网元于静态网元之间的数据转发问题,进而改善了传统机会路由算法的性能.

An opportunistic routing algorithm on the gathering point in the Internet of Things

The sensing devices in Internet of Things have obvious social attributes.In the designing of the forwarding policy,it needs to consider what the impact of social attributes devices of the sensing devices to routing algorithm performance.In the daily life and work,people exhibit the clustering behaviors.This paper proposed an opportunistic routing algorithm on the gathering point.Combining the traditional multi-backup routing mechanism and direct awaiting transmission strategy,the algorithm is that it places a static node in the accumulation region to support mobile nodes for data forwarding.It not only solves the data forwarding problems between the mobile network element but also between the mobile network element and the static network element,thereby improving the performance of traditional opportunistic routing algorithm.
