Review of multicast QoS routing protocols for mobile ad hoc networks
A Mobile Ad hoc NETwork (MANET) is consisting of a
collection of wireless mobile nodes, which form a temporary
network without relying on any existing infrastructure or
centralized administration. Since the bandwidth of MANETs is
limited and shared between the participating nodes in the
network, it is important to efficiently utilize the network
bandwidth. Multicasting can minimize the link bandwidth
consumption and reduce the communication cost by sending the
same data to multiple participants. Multicast service is critical for
applications that need collaboration of team of users.
Multicasting in MANETs becomes a hot research area due to the
increasing popularity of group communication applications such
as video conferencing and interactive television. Recently,
multimedia and group-oriented computing gains more popularity
for users of ad hoc networks. So, effective Quality of Service
(QoS) multicasting protocol plays significant role in MANETs.
In this paper, we are presenting an overview of set of the most
recent QoS multicast routing protocols that have been proposed
in order to provide the researchers with a clear view of what has
been done in this field
Issues in location-based multicast routing in manets
Mobile Ad Hoc Networks (MANETs) are an autonomous system of a set of mobile nodes connected by shared wireless links, forming a temporary network without relying on any
infrastructure. MANETs characteristics include self-organizing, self-configuring, multihop communication, continuous mobility and strict resource limitation. These characteristics coupled with the characteristics of the wireless communication medium make routing protocols one of the major issues to consider in MANET
Position-based QoS multicast routing protocol for mobile Ad Hoc Networks
Recently, the necessity of applications where many
users have to interact in a close manner over mobile Ad-Hoc
networks gains high popularity. Multicast communication is
essential in this type of applications to reduce the overhead of
group communication. For group-oriented multimedia
applications Quality of Service (QoS) provision is a basic
requirement, which makes an efficient QoS multicast routing
protocol a very important issue. This paper proposes a locationbased
QoS multicast routing protocol via cooperation between
Network and MAC layers. Along with this protocol, a location
and group membership management scheme has been proposed.
Unlike some of multicast routing protocols, the proposed
approach limits maintaining the network topology to certain
nodes to reduce control overhead and reduce bandwidth
consumption. Our proposed protocol is scalable for large area
networks with large multicast members regardless of the network
density. Also, it achieves a significant reduction in processing
overhead compared to flat QoS algorithms
Geographical Multicast Quality of Service Routing Protocol for Mobile Ad-Hoc Networks
Recently, the necessity of applications where many users have to interact in a close manner over mobile Ad-Hoc networks gains high popularity. Multicast communication is essential in this type of applications to reduce the overhead of group communication. For group-oriented multimedia applications Quality of Service (QoS) provision is a basic requirement, which makes an efficient QoS multicast routing protocol a very important issue. This paper proposes a location-based QoS multicast routing protocol via cooperation between Network and MAC layers. Along with this protocol, a location and group membership management scheme has been proposed. To further reduce the control overhead and bandwidth consumption, we apply clustering strategy by partitioning the network topology into hexagon cells. Thus, maintaining the network topology is limited to certain nodes. The performance of the proposed protocol is evaluated using GloMoSim simulation environment. Simulation results show that our approach provides high packet delivery ratio associated with low control overhead
