Resource Reservation and Improved QoS for Real Time Applications in MANET

Background/Objective: Real time data communication in Mobile Adhoc Network is a demanding issue due to the selfgoverning nature of mobile devices which are connected with each other by wireless links. Nodes frequently change their position and location remaining connected to the network which is without any base or any infrastructure. Careful considerations have to be made during designing the protocols for real time data transmission which are highly sensitive and time constrained. Common challenges faced by real time data transmission are efficient energy utilization, scalability of the network, optimized use of bandwidth, resource reservation, reducing chance of link failure, security, Quality of Service (QoS) consideration, dynamically changing topology etc. Methods/Statistical Analysis: Here, we present a cross layer communication centered quality of service platform with foundation of an energy optimized Ad hoc On- Demand distance Vector (AODV) protocol that uses a delay achieved and power efficient elevated routing algorithm at the network layer as part of the QoS platform. Secondly enhanced method of resource reservation such as bandwidth management, reduced power consumption with longevity of residual power of highly movable nodes has been implemented with co-ordination of data link layer for smooth transmission of real time packets over the network with minimum queuing delay and propagation delay. Results: Simulation result produces better efficiency of our proposed architecture in terms of better packet delivery ratio and improved network life time when compared with other similar approaches. Application: The proposed architecture provides efficient QoS aware routing with resource reservation in MANET.
