Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. However, resource reservation in ad-hoc networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between mobile nodes. Proposed reservation MAC protocols like CATA, FPRP, R-CSMA and(More)
Movements of nodes in MANETs result in route changes, thus requiring the transmission of control packets. As MANETs have limited resources, it is important to reduce the number of control packets which consume bandwidth. We propose a AODV-based protocol which uses a backbone network to reduce control packets. The destination location is given by GPS and(More)
Bandwidth reservation in wireless networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between nodes. Reservation MAC protocols define a super-frame and allocate as lot to each real-time traffic source. However, the use of fixed length super-frame may result in bandwidth wasting, especially(More)
