A Master-Sink Based Model For On-Site Tracking Of Multiple Mobile Targets In Wireless Sensor Networks
2005 INTERNATIONAL CONFERENCE ON INTELLIGENT SENSING AND INFORMATION PROCESSING, PROCEEDINGS(2005)
摘要
The problem of on-site tracking of a mobile target in wireless sensor networks has been introduced recently [17]. The on-site tracking requires the physical presence of the sink in the area of interest. This paper generalizes the on-site tracking problem for multiple mobile targets and then purposes an energy efficient solution to solve it. The solution is an extension of the ant based method proposed in [17] for onsite tracking of a single target. The introduction of multiple tracking units (sinks) requires coordination among themselves for efficient tracking. This coordination among the sinks in our approach is achieved through a master sink. We conducted a simulation study and compared out approach with TTDD[10] and SPC[17] for the on-site tracking of multiple targets. Our approach is simple and the simulation results show that it is efficient energy.
