Abstract:

In application of data gathering in Wireless Sensor Network(WSN), the moving Sink will break the routing at last hop, and reconstruction of the routing is a heavy spending. This paper proposes a local routing maintenance mechanism for mobile Sink. It makes use of power control to reduce the routing break and conditional refresh of the entire routing to reduce the broadcast packet, delay and energy consumption. Sink's mobile performance is increased via power control.

摘要：

针对无线传感器网络数据汇集应用中Sink节点移动导致路由中断和重建路由开销大等问题，提出一种支持移动Sink的局部路由维护机制。该机制通过对Sink节点路由维护消息的功率控制，降低路由中断的可能性，增强Sink的移动性能。采用局部路由维护机制和有条件的全路由刷新减少网络广播消息，降低数据传输延迟和能耗。
