基于聚簇的多跳路由协议的研究

为适应大规模无线传感器网络的应用，进一步均衡网络中节点负载，提出一种基于聚簇的多跳路由协议（CBMRP）。协议基于聚簇的思想，簇首进行簇内数据融合后，结合一简单的启发函数和网关剩余能量选取合适的网关，将融合后的数据利用网关在簇首间转发，最终传送到基站。协议充分考虑了数据冗余性的消除及数据传输过程中节点能耗的均衡，可进一步延长网络生命周期。

Research of cluster-based multi-hop routing protocol

In order to adapt to the application of large-scale wireless sensor network and further balance the load of each node, a Cluster Based Multi-hop Routing Protocol (CBMRP) was proposed. This protocol was based on the concept of clustering. Cluster heads first fused data collected by member nodes. Then on the basis of a simple heuristic function and the residual energy of the gateways, they selected appropriate gateways, through which to route the fused data among clusters, and finally transmit to the base station. Because this protocol takes account of reducing redundant data and balancing power consumption during transmission, it can further prolong the lifetime of the whole network.
