深井无线传感器网络非均匀分簇路由协议

针对深井巷道狭长的地理特点,提出了一种无线传感器网络非均匀分簇的路由协议(UCRP).将狭长WSNs看作是线型网络,并对网络进行合理规划,距离Sink节点较近区域的竞选半径较小,可减少转发数据的能耗,并构造一个新的权值公式来选举候选簇首,候选簇首以一定的竞争半径来竞选成为最终簇首,采用单跳与多跳结合完成簇内和簇间的数据转发.仿真实验表明,UCRP协议能有效解决线型网络中由于负载能耗不均导致的"热区"问题,延长了整个网络的生存周期.

Uneven Clustering Routing Protocol for Wireless Sensor Networks in Deep Mine

An uneven routing protocol named UCRP of wireless sensor networks is proposed according to the long-narrow geographical characteristics of deep roadway. Long-narrow WSNs is treated as linear network which is well planned, making the campaign radius closer to the sink node with smaller nodes, which can preserve some energy for inter-cluster data forwarding. An new weight formula is constructed to elect the candidate cluster heads which determine cluster heads by certain campaign radius. Data forwarding is accomplished by single-hop within the cluster and multi-hop between the cluster heads. Simulation results show that UCRP can solve the hot-spot problem caused by uneven load energy in linear network, and prolong the entire network life.
