QTM: A QoS Task Monitoring System for Mobile Ad hoc Networks

This paper presents monitoring system for Quality of Service (QoS) based task module called QoS Task Monitoring (QTM) in Mobile Adhoc Networks (MANET) using mobile agent as basic element. Currently MANET is one of the most promising and advanced solution for wireless networks due its significant performance in resuming connectivity in drastic situations. In such environment, there is maximum chance of network disconnection and possibility of immediate set up of network is almost impossible. The fundamental routing process in a MANET involves facilitating uninterrupted communication in the network system between two mobile stations at any point of time and the basic key concern being selection of the most suitable forwarding node to advance the real-time packets from source towards destination so that the optimization of the network can be achieved by maximum utilization of available resources. Transmission of real-time applications is one of the most challenging issue in MANET due to transportation of high volume of data including audio, video, images, animation, and graphics. This paper presents a monitoring approach for checking the Quality of Service (QoS) task modules during competent routing with the use of mobile agents. An intelligent mobile agent is proposed in QTM System which has been designed in the QoS-based platform for checking and controlling the processing tasks using longest critical path method at the forwarding node to select it as the best option out of all neighbor nodes. Simulation result shows higher packet delivery ratio and uniform jitter variation which suits favorably to multimedia and real time applications.
