地理路由算法在Duty-Cycle网络中的研究

Study of the Geographic Routing Algorithm in Duty-Cycle Networks

文章提出了Duty-Cycle网络中的地理路由算法MMGR(多度量地理路由)。这个算法所考虑的度量因素不仅包括传统地理路由中提到的地理距离,也包括候选节点睡眠延迟的Duty-Cycle。经仿真表明,在Duty-Cycle网络中,这种新的算法在端到端的延迟方面比传统的GR(地理路由)算法有更好的效果。

In this paper,a geographic routing algorithm MMGR（multi-metric geographic routing） with the network condition of duty-cycle is proposed.This algorithm considers the metric containing not only the geographic distance like the traditional geographic routing algorithm,but also the duty-cycle sleeping delay of the candidate node.Simulations are carried on to evaluate that this new algorithm performs better on the aspect of end-to-end delay than the traditional GR（Geographic Routing） algorithms in the duty-cycle networks.
