一种用于事件监测的传感器网络拓扑控制策略

A sensor network topology control strategy for event monitoring applications

针对事件驱动型传感器网络应用系统,基于简化的AODV(ad hoc on-demand distance vector routing)(S-AODV)算法,提出一种结合预先路由和按需路由的混合拓扑控制策略,通过随机选择一部分节点预先运行S-AODV算法来减小事件发生时任务节点的初始拓扑建立时延.仿真实验表明,该策略能以较小的能耗代价换取较快的系统响应速度,满足了事件监测类应用的实时性要求.

For event-driven sensor network applications, based on a simplified AODV（ad hoc on-demand distance vector routing） （S-AODV） algorithm, a hybrid topology control strategy combining with a pre-routing and on-demand routing idea is proposed. By using random pre-selection of nodes running S-AODV algorithm, the initial delay of the topology establishment between task nodes when the events are monitored is reduced. The simulation result shows that the strategy can take a smaller cost of energy in exchange for faster system response time to meet the real-time requirements of the event monitoring applications.
