Delay performance of packet transmission in wireless ad hoc networks is highly dependent on the underlying medium access control (MAC) protocol. Since most delay-sensitive applications are transmitted in a multicast fashion, a dedicated access model for multicast is, therefore, needed to represent the actual characteristics of multicast packet access mechanisms. In this paper, a multicast station...
In this paper, we discuss the issue of delay-throughput tradeoff from providing end-to-end delay guarantee multicast service in wireless ad hoc network. Efforts are made to develop a Delay Constraint Multicast (DCM) routing protocol, focused on constructing a delay based multicast tree, which is able to provide soft end-to-end delay guarantees for all multicast receivers. Forwarding decisions are...
Congestion due to high traffic rates and node density is one of the main challenges for multicast routing in mobile ad hoc networks (MANETs). A congestion detection scheme is proposed to improve the overall performance of such networks in both static and dynamic MANETs. Without degrading the protocol efficiency under normal network conditions, our proposed enhancement enable efficient use of bandwidth,...
Mobility prediction is one the most efficient techniques used to calculate lifetime estimation of wireless links (link lifetime-LLT) for a more reliable path selection. To incorporate a mobility prediction model into ad hoc routing protocols, an updating scheme should be used to maintain prediction accuracy especially for those source initiated on-demand routing protocols where LLT values are continuously...
