摘要:
为了改善无线传感器网络在重负载情况下的性能,提出了一种多信道动态路径转发协议MDFP.该协议通过整合动态路径选择和预测唤醒调度,使得发送者在发送数据前能预测可用转发节点的唤醒时间,避免了现有动态路径转发协议依赖长前导来完成转发节点选择和数据传输所带来的问题,从而实现更低的能耗并改善网络在重负载下的延时和可靠性.MDFP利用多信道通信减少节点间干扰,从而进一步提升网络在重负载情况下的可靠性.基于TelosB节点的实验结果表明,在重负载情况下,相对于现有的动态路径转发协议,MDFP在能耗、延时和可靠性方面均有较明显的性能提升.
Abstract:
To improve the performance of wireless sensor networks in heavy traffic conditions, a multichannel dynamic-path forwarding protocol(MDFP)is proposed. By integrating dynamic-path selection with predictive-wakeup schedule, a sender can predict the wakeup time of available forwarders so that it can avoid relying on sending long preambles to determine the forwarder and transmit data. This helps to achieve lower energy consumption and improve delay and reliability of the network in heavy traffic conditions. The MDFP exploits multichannel communication to reduce interference between nodes, so that the reliability of the network in heavy traffic conditions can be further improved. The experiment results on the TelosB testbed show that, in heavy traffic conditions, compared with the state-of-the-art dynamic-path forwarding protocol, the MDFP shows better performance in terms of energy efficiency, delay and reliability.
