Cluster Gateway Dominating Set Optimization Strategy in Wireless Ad Hoc Network
Wang Guang-xing · Jisuanji gongcheng · 2007
In the Ad hoc network cluster,the gateway is responsible for forwarding message.The node that can logically communicate with the nodes in other clusters has the ability to be gateway,and the set of these nodes is defined as gateway dominating set relative to cluster-head.In order to reduce the redundant gateways in the set,this paper presents a strategy of optimizing gateway dominating set by comparing the exclusive id of each node.However,there is only one gateway in the intersecting cluster and there is a couple of gateways in the neighborhood clusters.Simulation results show that the method can save the broadcast packets and reduce broadcast delay effectively in the case of guaranteeing the network connectivity.
