A Sensor Awaking Strategy for Wireless Multimedia Sensor Networks Target Tracking

Abstract

Concentrating on node scheduling in tracking target across special region with uniform speed, the authors put forward a strategy for target tracking in wireless multi-sensor networks. The corresponding algorithm working depends on the virtual potential method. To sense target dynamically by sense nodes, we structure virtual force between moving target and the current sense node, then select the next sense one with information gain function so that as few nodes as possible are used to get the maximum probability of motion trajectory sensing when target cross the specific areas. The proposed algorithm is verified from the simulations.
