Proposal and Performance Evaluation of a Multicast Routing Protocol for Wireless Mesh Networks Based on Network Load

Abstract

Wireless Mesh Networks (WMNs) can provide wide range Wireless Local Area Networks (WLANs) area by connecting Access Points (APs) of WLANs with each other using radio communications. A routing protocol is very important to keep communication quality over radio multihop communications because radio waves are impacted much by surrounding environment. When we use multiuser shared applications like a video conference and an IP phone, it is predicted that large amount of traffic flows on network. Therefore, we should consider network loads to use these applications. In this paper, we propose a multicast routing protocol for WMNs which considers network loads and hop count. Furthermore, we evaluate performance by simulation. In the simulation results, we show that the proposed protocol has better performance than a conventional protocol (MAODV) at high loaded scenario.

A multicriteria adaptive opportunistic treecast routing protocol for multimedia dissemination in vehicle-to-vehicle telescreen

“…In PAMTree, the source selects a route to each group member which may not be appropriate in dynamic topologies. An improved multicast ad hoc on-demand distance vector (MAODV) protocol considered the network load from the RSU to the destination node as path selection criteria [ 22 ]. Another research study focused on the adjustment of the transmission rate and the power level of the physical layer to minimize PLs due to interference [ 23 ].…”
