Fuzzy-based target tracking on “Vehicular Grid Sensor Networks”

In Vehicular Grid Sensor Network (VGSN), because the operation of individual vehicles and mobile speed and direction, contact between them fragile and unstable. It has multicast links suddenly fail to overcome the problems, so that the message flows to each node, and increase the volume of traffic control. In this paper, we propose a fuzzy-based target tracking scheme that will re-route the link path when the link becomes weak so as to maintain the vehicle-to-vehicle connections to make the whole VSN more stable. In addition, due to the arbitrary speeds of vehicles, the sensors installed in different vehicles may have different reaction times. We also take into account a suitable alarm range as the moving speed changes, although this action increases the control overhead. Despite this reduction in average latency, this intelligent approach enables higher survivability and more effective on re-routing.
