提出了一种适于无线传感器网络基于能量感知节能高效的QoS路由协议EEQRP,该协议通过将流量分配到可用的多条邻接节点路径上来恢复节点故障和实现负载均衡,通过多路径路由和前向纠错技术来恢复节点故障,在路径发现阶段使用节点剩余能量,可用缓存大小和信噪比来预测下一跳节点。将要传输的信息分割为多个大小相同的子包,并添加纠错码,然后在多条路径上同时传输;通过队列模型来有效地提供实时和非实时通信的差异性服务,从而在多个传感器节点上有效地均衡能量消耗。利用NS2对协议EEQRP与传统协议MCMP进行了仿真实验研究。结果表明,与传统协议MCMP相比,EEQRP协议实现了较低的平均延迟、更少的能量消耗和更高的包投递率。
This paper proposes a energy-efficient and energy-efficient QoS routing protocol for wireless sensor networks (EEQRP). This protocol restores node failures and balances the load by allocating traffic to available paths of multiple adjacent nodes. By multipath routing and forward The error correction technique is used to recover the node failure. During the path discovery phase, the remaining node energy is used to predict the next-hop node based on the size of the buffer and the signal-to-noise ratio. The information to be transmitted is divided into a plurality of subpackets of the same size and error correction codes are added and then transmitted simultaneously on multiple paths; the queue model is used to effectively provide differentiated services of real-time and non-real-time communications, The sensor nodes effectively balance the energy consumption. The NS2 is used to simulate the protocol EEQRP and the traditional protocol MCMP. The results show that the EEQRP protocol achieves lower average latency, less energy consumption, and higher packet delivery rates than the traditional protocol MCMP.
