Effective Scheduling Strategy in Wireless Multimedia Sensor Networks for Critical Surveillance Applications

PP: 101-111
Ahmed Salim, Walid Osamy, Ahmed M. Khedr,
A wireless multimedia sensor network (WMSN) consists of a set of interconnected, battery-powered miniature video cameras, each packaged with a low-power wireless transceiver that is capable of processing, sending, and receiving data. A WMSN can operate in an Ad-hoc manner and hence does not require a network infrastructure which adding a much higher level of flexibility and allowing a wider range of applications such as video surveillance, health care, industrial process control, and traffic management. In this paper, we propose a new dynamically efficient strategy to schedule the activities of sensor nodes in mission-critical surveillance applications according to the node’s redundancy level. Simulation results show that our strategy outperforms the existing work in terms of average capture rate, network lifetime, and percentage of active, sleep, and dead nodes.
