Priority-based adaptive rate control for wireless sensor networks

In many real world environment, a wireless sensor node may have to gather different types of data obtained from a variety of sensors. Each of the data may have different priorities to be processed. Often, real time traffic could be one of the data to be handeled by the sensor node and to be successfully transmitted to the sink node. Therefore, rate control in wireless sensor node (WSN) plays a pivotal role. In this paper, we present a priority based rate control algorithm to take care of different data. The input traffic consists of real time as well as non-real time traffic data. The performance of the algorithms has been found to be superior to the algorithm proposed by Yaghmaee et al. with respect to throughput, delay, and loss.
