【摘要】 因为节点的随机撒布及无线传感器网络的流量不均匀特性,使得跳数场路由中的节点负载极不均衡。在充分论证跳数场路由性质基础上,针对此问题提出负载均衡的多组跳数场路由协议。该协议通过引入组内及组间均衡机制,较为有效地均衡了节点间的负载,从而较大程度地延长了网络生存期。模拟实验显示,改进后网络寿命较之前平均延长80%。更多还原

【Abstract】 Due to random deployment of nodes and unbalanced traffic in wireless sensor networks,the nodes’ load is imbalanced when using Hop Count Routing(HCR).To address this issue,the Load-leveling Multi-groups Hop Count Routing(LMHCR) based on expounding on the property of HCR was proposed in this paper.LMHCR presented can balance the nodes’ load effectively and extend the network’s life span by importing intra-group and inter-group leveling mechanism.The simulation experiment shows that the improved routing mechanism extends the average life span of the network by 80% than the previous.更多还原
