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)
INTRODUCTION Mobile ad-hoc networks (MANETs) are collections of mobile nodes forming temporary networks without any infrastructure support. They can be set up anywhere anytime owing to their easy deployment and self-organization ability. As a result, MANETs become the primary mean of communication in several domains where the deployment of wired… (More)
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)
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)
Bandwidth reservations established by a node should be reported to all its neighbors and any missed or unrecorded reservation may have negative impact on already established reservations. In this paper we propose a robust reservation protocol (RRP) to tackle these situations.
Due to the On/Off nature of voice traffic, resource reservation for voice traffic in ad-hoc network is a very challenging task. On one hand, allocating resource to voice sources for all the duration of the connection results in bandwidth wasting because of the Off periods. On the other hand, releasing resources during the Off periods and reallocating them… (More)
Bandwidth reservation is an alternative approach to provide QoS in mobile ad-hoc networks. However, unlike in cellular networks where resources are controlled by a centralized entity, bandwidth reservation in ad-hoc networks is a more challenging task because of instability of radio channels, nodes mobility and lack of coordination between mobile nodes.… (More)
