【摘要】 为了适应煤矿井下巷道窄长的空间结构和复杂的环境,提高网络的稳定性和传输效率,提出一种能耗均衡跨层WSN路由传输协议(EBUCR)。分析数据传输不对称造成的网络能量空洞现象,提出基于有效密度函数ρ(x)的非均匀分簇算法,并在此基础上结合跨层设计思想,将下一跳路由节点的链路可用带宽和节点负载容量作为选取路由节点的重要因素。仿真实验表明,与LEACH,HEED和EEUC三种算法比较,EBUCR满足非均匀分簇策略,有效的优化了网络的能量消耗,延长了网络的生命期,提高了网络吞吐量和传输率,更适用于井下巷道内大规模部署的节传感器节点数据传输控制。更多还原

【Abstract】 In order to adapt to the space structure and environment characteristics of coal mine roadway,and improvethe performance and prolong the lifetime of a network,this paper presents an energy efficient cross-layer routing mech-anism for wireless sensor network in the environmental monitoring in coal mine roadway. The authors theoretically ana-lyze the problem of unbalanced energy exhaustion among cluster heads in the whole network,and calculate the effec-tive density function(ρ(x)) which is used for cluster head selection. The authors also present a cross-layer routingscenario with the cluster heads selection strategy,which considers available link bandwidth and available queue bufferlength of routing nodes. Simulation results show that the proposed scheme outperforms other algorithms in terms of theenergy balance of average node,prolongs the network lifetime and improves network throughput and packet delivery ra-tio. The EBUCR is more suitable for the monitoring in coal mine roadway.更多还原
