The mission-oriented self-deploying methods for wireless mobile sensor networks

Abstract

In the mission-oriented mobile sensor networks, the mobile sensor nodes actively organize and deploy themselves when an event arises in the target location. The mobile sensor nodes are instructed by the base station to build a communication path to the location of the event quickly. In this paper, two greedy methods are proposed to organize the mobile sensor nodes as the shortest communication path from the monitor node to the target location. To reduce the deploying time and save the energy consumed on moving, the sensor node with minimal moving distance is instructed to move. The proposed method can automatically organize the sensor nodes to build the communication path even the initially deployed network is disconnected. Simulation results show that the proposed methods can reduce the moving distance and shorten the deploying time. © 2010 Springer-Verlag Berlin Heidelberg.
