摘要
传统的机会路由在设计路由测度时仅考虑候选节点外部链路因素,而忽略了节点自身因素对网络性能的影响。针对此问题,文中提出了一种基于节点缓冲区与能量的机会路由协议。该协议在地理位置策略的基础上,综合考虑节点缓冲区和能量因素设计新的路由测度,并根据该路由测度设计下一跳转发节点的选取方法和每一跳的数据转发过程。仿真结果表明,与EAOR协议相比,BEAOR协议可以获得更高的网络吞吐量以及更低的端到端时延,能更好的适应无线传感网络。
The traditional opportunistic routing considers only the external link factors of the candidate node while designing the routing metric,while ignoring the influence of the node's own factors on the network performance.To solve this problem,this paper proposes an opportunistic routing protocol BEAOR considering node buffer and energy.Based on the GeRa F,this protocol takes into account the node buffer and the energy to design a new routing metric,and according to the metric,the selection method of next hop forwarding node and the data forwarding process of each hop are designed.The experimental results demonstrated that the proposed protocol can obtain higher network throughput and lower end-to-end delay compared to EAOR,and it can better adapt to the wireless sensor network.
