中文摘要:
      节点的移动对移动无线传感网络(Mobile Wireless Sensor Networks, MWSNs)路由设计提出了挑战。为此,提出基于接触时间的能耗区路由(Contact time-Energy consumption area based Routing, CECA)。CECA路由采用休眠-唤醒机制,降低了节点能耗。CECA路由利用源节点与信宿的位置信息构成圆角矩形区域,且只允许区域内的节点才能参与路由。通过节点移动信息,计算接触时间,并利用接触时间设置定时器,进而通过定时器竞争产生下一跳转发节点。仿真数据表明,提出的CECA路由的通信连通时间及数据包传递率得到较大提高。
英文摘要:
      The movement of nodes challenges the design of routing in Mobile Wireless Sensor Networks (MWSNs).Therefore, Contact time-Energy consumption area based Routing (CECA) is proposed in this paper. In CECA routing, all the nodes follow a sleep-wakeup pattern to improve energy efficiency. Communication between the source and the sink is established by creating a rounded rectangle region. Only the nodes in rounded rectangle region participate in the routing. The contact-time between source and neighbor node is computed by mobility information, and the timer is set by contact-time. The next-hop forwarding node is selected by timer. Simulation results indicate that CECA protocol has better performance in term of packet delivery ratio and connection-time of routing.
