负载均衡的多组跳数场路由决策机制

Load-leveling multi-groups hop count routing

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%。

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 prdperty 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.
