Precedence Based Preemption and Bandwidth Reservation Scheme in MANET

Infrastructures less mobile networks are commonly known as Mobile Ad Hoc Networks (MANET). Quality of Service (QOS) constraints is highly required for multimedia communications with MANET. Providing QOS in MANET is not easy task due to its broadcast and dynamic nature. There are some number of protocols exist which takes care for the QOS. Some of them are Diffserv, Intserv, AQR etc. All have some limitations. This paper propose a protocol Preemption And Bandwidth Reservation Scheme (PBRS) which adds more functionalities with AQR and added with AODV. In addition to reserving bandwidth it will also provide preemption scheme. It will minimize number of preemption and will assure that preemption is being done fairly. Case studies between AODV and PBRS shows the added advantage of PBRS over AODV in terms of priority and preemption.
