无冲突的无线传感器网络广播算法

无线传感器网络的节点众多,各种资源严重受限,广播引起的冗余转播加剧了资源的消耗,因而慎重选择转播节点非常关键.提出了一种无冲突的广播策略,该策略利用邻节点能量和度等信息构建最小连通树,减少了转播节点的数量,同时对最小连通树中的节点的转播进行调度,避免冲突的发生.该策略减少网络中节点的能量消费、延长了网络寿命,同时确保了广播的可达性.仿真结果表明该算法提高了广播的效率.

Collision-free broadcasting strategy for wireless sensor networks

Many of sensor nodes can spontaneously establish wireless sensor networks.Broadcasting is a common operation in wireless sensor networks with severe resource constraints.Retransmissions use up valuable resources in the network.It is important to choose the intermediate nodes carefully so as to avoid redundancy in retransmission.The efficient broadcasting strategy without collision for wireless sensor networks is proposed which is made use of 1-hop neighbor knowledge,such as the surplus and degree of node to...
