In the few last years, there is an increasing need of QoS guarantees for multimedia and real time applications in mobile ad hoc networks. While several QoS routing protocols were proposed, adaptive routing has not be enough exploited. This paper introduces a new multipath quality of service (QoS) routing protocol for mobile ad-hoc networks (MANETs) called QoSBeeManet. Based on the autonomic bee communication...
The emergence of multimedia applications demands multicasting in MANETs. For such applications QoS provisioning is a complex and challenging issue. This paper proposes a QoS aware multicast routing scheme uses a set of static and mobile agents and ensures QoS guarantees in terms of bandwidth reservation, delay constraint, delay-jitter constraint and packet loss to multicast session. Here the mobile...
In mobile ad hoc networks, channel bandwidth is a very limited resource. When the network is heavily loaded, the rate of collisions and hence the number of retransmissions increase. This leads to a notable decrease in network throughput and hence reduces quality of service because more and more bandwidth is wasted. MAC layer enables sharing the channel among all the nodes in the network effectively...
Due to the dynamically varying network topology ofad-hoc networks, the admitted quality of service suffers from frequent path breaks that require network re-establishment over new paths. Thus, rendering ad-hoc networks inappropriate for real-time interactive sessions, e.g., video or audio calls. TORA is a distributed, loop-free, multipath routing protocol for multi-hop networks which supports both...
Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. A major challenge lies in adapting multicast communication to environments where mobility is unlimited and failures are frequent. The multicasting concept deals with one to many data dissemination, many multicast routing algorithm have been proposed like ODMRP, CAMP, NTPMR and so on. In this paper we design...
