摘要:

针对无线传感器和参与者网络的通信机制进行了研究。首先,提出了一种主动位置管理机制,它基于移动参与者发送给传感器的更新消息和Voronoi图限制的参与者范围,从而使传感器采用先前接收到的更新卡尔曼滤波来预测参与者的移动;然后,提出了一种基于地理路由的最佳能量感知转发规则作为传感器-参与者之间的通信,并采用功率控制来控制数据传输过程的时延,通过迫使多个参与者共享事件区域产生的流量来处理网络拥塞;最后,基于多个并发事件的特征,提出了一种参与者-参与者之间的协作模型来协调它们之间的运动,以最佳地完成任务。性能仿真结果表明,提出的关于无线传感器和参与者网络的协作通信机制能够有效地减少端到端时延、能量消耗和分组丢失百分比。

Abstract:

The communication mechanism of wireless sensor and actor network (WSAN) was studied.Firstly,a proactive location management mechanism based on the update messages sent by mobile actors to sensors and the actors’ scope limited by Voronoi diagram was proposed.Thus,sensors predicted the movement of actors using Kalman filtering of the previously received updates.Then,an optimal energy-aware forwarding rule based on geographical routing was presented for sensor-actor communication,and the delay of the data delivery process was controlled using the power control and the network congestion was dealed with by forcing multiple actors to share the traffic generated in the event area.Finally,based on the characteristics of multiple concurrent events,a model for actor-actor coordination was proposed to coordinate their movements in order to optimally accomplish the tasks.Performance simulation results show that the proposed cooperative communication mechanism for WSAN can effectively reduce end-to-end delays,energy consumption and percentage of packet drops.

Key words: wireless sensor and actor network, Voronoi diagram, geographical routing, power control, network congestion
