Abstract

One of the major applications of wireless sensor networks is guiding navigation service with its goal to assist moving objects in leaving a hazardous region safely and quickly. In this paper, we propose a distributed guiding navigation protocol that can guide moving objects to multiple exits with load balancing among multiple navigation paths to the exits. With the assistances of sensor nodes, moving objects are guided to different navigation paths so that they can move to exits as soon as possible without causing congestion. In some traditional navigation algorithms, a sensor may select a wrong guiding direction when an information- updating packet has not flooded through the whole network. Hence, the guiding direction of the sensor may oscillate in a short time and guided objects will confuse with this phenomenon, called direction oscillation problem. This problem will be eliminated in our proposed protocol. Simulation results indicate that our protocol can guide moving objects to exits in shorter time and solve the direction oscillation problem effectively.

一种负载均衡的无线传感器网络引导导航协议

无线传感器网络的主要应用之一是引导导航服务，其目标是帮助移动物体安全快速地离开危险区域。本文提出了一种分布式引导导航协议，该协议可以将移动对象引导到多个出口，并在多个出口导航路径之间实现负载均衡。在传感器节点的帮助下，将移动物体引导到不同的导航路径，使其能够尽快移动到出口，而不会造成拥堵。在一些传统的导航算法中，当信息更新包还没有遍布整个网络时，传感器可能会选择错误的引导方向。因此，传感器的引导方向可能在短时间内发生振荡，被引导物体会对这种现象产生混淆，称为方向振荡问题。这个问题将在我们提出的协议中消除。仿真结果表明，该协议能在较短的时间内将运动物体引导到出口，有效地解决了方向振荡问题。
