Energy consumption of the nodes is an important issue while designing multicast routing algorithms for MANETs’ and therefore, an efficient routing protocol needs to be energy conserving so that battery life of each individual node as well as lifetime of the network can be prolonged. This paper proposes a power efficient multicast routing protocol for mobile ad hoc networks called “Power Aware M...

The exponential growth of the Multicast Backbone (MBone) has resulted in increased routing overhead and processing costs. In this paper we propose a two-level hierarchical routing model as a solution to this problem. This approach involves partitioning the MBone into non-overlapping regions using DVMRP as the inter-region routing protocol; intra-region routing may be accomplished by any of a nu...

With conventional dynamic routing algorithms, many query messages are required in a distributed environment for e cient multicast routing of any tra c volume. We have developed a dynamic routing algorithm that uses a predetermined path search in which an appropriate multicast path is dynamically constructed by searching only a few nodes. This algorithm can construct an e cient multicast tree fo...

Multicast Routing in Mobile Ad hoc NETworks (MANETs) is a recent research topic. In this paper, we present a performance study of three multicast protocols: ODMRP, ADMR, and SRMP. Source Routing-based Multicast Protocol (SRMP) is a new on-demand multicast routing protocol that applies a source routing mechanism and constructs a mesh to connect group members. The strength of SRMP lies on its nod...

| Reducing forwarding state overhead of multicast routing protocols is an important issue towards a scalabile global multicast solution. In this paper, we propose a new approach, Dynamic Tunnel Multicast, which utilizes dynamically established tunnels on unbranched links of a multicast distribution tree to eliminate unnecessary multicast forwarding states. Analysis and simulation results show p...

Different multicast routing protocols construct their distribution trees based on the information obtained from the unicast routing infrastructure. Nevertheless, the design of most of these protocols do not take into account that unicast routes may be asymmetric. Indeed, unicast routes in the Internet are very asymmetric. The effects on the quality of the multicast trees vary according to the r...

Recently, multimedia and group-oriented computing become increasingly popular for the users of wireless mobile networks. Quality of service (QoS) issues has initiated to be studied in Mobile Ad hoc NETworks (MANETs) to support multimedia and real-time applications. MANETs can provide users with the mobility they demand, if efficient QoS multicasting strategies are to be developed. In this paper...
