Controlling the mobility of sensors in Sweep Coverage based on Dynamic POIs
Ji Zhou · Journal of Sichuan University · 2012
To address the mechanism of previous studies Sweep Coverage POIs always predetermined, static,and its location,and time interval information fixed,inflexible problem,proposed a mechanism called DDSweep based on the concentration of pheromone Sweep Coverage.When a new POI appear,disappear with the old POI that POIs are event-driven,dynamic,there is removed into the POI.In the absence of a centralized control case,the mechanism allows the mobile node at the time to collect their data. Simulation results show that,DDSweep mechanism is more adapted to Dynamic POIs real environmental than the previous Sweep Coverage mechanisms.
