Abstract

Wireless sensor network has been widely used in many types of monitoring application in these recent years. For monitoring application such as forest or building monitoring, sensor nodes equipped with temperature sensor, smoke detector and camera will trigger immediately when a fire breaks out. Due to those sensor nodes are transmitting the sensor packets to a sink node at the same time and without a proper control, the traffic will be congested and causing huge amount of packet losses in this situation. Therefore, a priority scheme is needed to allow some selected nodes' information to reach the base station for the sake of data completeness. This paper evaluates the performance of priority packet in a congested traffic.
