摘要:

在时间关键的无线传感器网络(WSN)应用中,通常需要高度的可靠性。提出了一种动态跳变实时的【形】容错路由协议(DMRF)。每个节点利用数据包的剩余传输时间和转发候选节点集的状态来动态选择下一跳。一旦节点发生故障、网络拥塞或出现空洞区域,传输模式将切换到跳跃传输模式,这样可以减少传输时延,保证数据包在规定的时限内发送到目的节点。通过反馈机制,各节点动态调整跳变概率,提高传输成功率。仿真结果表明,DMRF不仅能有效地降低失效节点、拥塞和空洞区域的影响,而且能获得更高的传输成功率、更小的传输延迟和更少的控制包数量。

英文摘要:

In time-critical wireless sensor network (WSN) applications, a high degree of reliability is commonly required. A dynamical jumping real-time fault-tolerant routing protocol (DMRF) is proposed in this paper. Each node utilizes the remaining transmission time of the data packets and the state of the forwarding candidate node set to dynamically choose the next hop. Once node failure, network congestion or void region occurs, the transmission mode will switch to jumping transmission mode, which can reduce the transmission time delay, guaranteeing the data packets to be sent to the destination node within the specified time limit. By using feedback mechanism, each node dynamically adjusts the jumping probabilities to increase the ratio of successful transmission. Simulation results show that DMRF can not only efficiently reduce the effects of failure nodes, congestion and void region, but also yield higher ratio of successful transmission, smaller transmission delay and reduced number of control packets.
