ad-Hoc Networks: analysis of the approaches
Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. Several researches were done to propose efficient reservation MAC protocols for ad-hoc networks. In these schemes, channel is segmented into super-frames composed of fixed number of slots. They allocate slots to each traffic source, and make sure that neighbor nodes record the rese...

متن کاملPerformance Analysis of Reservation MAC Protocols for Ad-hoc Networks
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 SRMA/PA have limitations and are suitabl...
متن کاملQos-aware, Adaptive Throughput-enhancement for Csma- Based Mobile Ad Hoc Networks
Mobile ad-hoc networks (MANETs) are considerably appealing especially for military and desaster recovery communication applications since they offer two distinct advantages: easy setup due to the absence of an infrastructure, and robustness because MANETs have no single point of failure. As MANETs generally allow a flexible number of participating nodes the preferred medium access protocol is C...
متن کاملCongestion Aware and Control routing in Mobile Ad-hoc Networks: Current State of the Art
With the increase of multimedia traffic over the past few years and traffic differentiation introduced by IEEE 802.11e, nodes with packet loss, delay-sensitive multimedia traffic tend to be busy for long periods, thus exacerbating the congestion problem in mobile ad hoc networks (MANETs). In this paper, we first expose that the performance of MANETs routing protocols is highly dependent on the ...
