在基于分簇的无线传感器网络中,为了有效地转发数据,研究者们提出了各种簇组织和簇首选举机制,但是这些机制缺少关注簇首与汇聚节点之间数据传输的可靠性。针对该问题,提出一种可靠的数据路由方案,通过链路代价函数和动态的簇首间路由,控制簇首到汇聚节点的数据转发。仿真结果表明,该方案不仅有效地增加数据包的投递率,也能够均衡网络的能量消耗。 In cluster-based wireless sensor networks, researchers have proposed various cluster organization and cluster head election mechanisms in order to forward data efficiently. However, these mechanisms lack the reliability of data transmission between cluster heads and sink nodes. Aiming at this problem, a reliable data routing scheme is proposed to control the data forwarding from the first cluster to the second aggregation node through the link cost function and the dynamic first cluster routing. The simulation results show that this scheme not only effectively increases the delivery rate of data packets, but also balances the network energy consumption.
