Optimized Bandwidth Utilization for Real Time Applications in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) are special types of networks used in information gathering in military, industrial, and surveillance applications. Many such applications of WSNs require Quality of Service (QoS) in terms of high bandwidth for real time applications including multimedia audio and video without much delay. These applications demand high packet delivery ratio and are extremely delay-sensitive. However, certain factors limit the ability of the multi-hop WSNs to achieve the desired goals. These factors include the delay caused by network congestion in the network, limited energy of the sensor nodes, packet loss due to collisions and link failure. In this paper, the authors propose an optimized bandwidth adaptation and utilization algorithm for real time applications in WSNs.
