In this paper, we focus on the problem of effectively supporting a large number of small group multicasts in optical burst switched (OBS) networks. We first propose a multicast scheme for small group multicast in OBS networks. To reduce burst loss due to potential burst contentions, a deflection routing scheme for multicast is proposed. We then develop an analytical model to evaluate the perfor...

Multicast routing algorithms that are capable of providing quality of service (QoS) to its members will play an important role in future communications networks. This paper discusses some fundamental properties of multicast routing subject to multiple QoS requirements. We will show that guaranteeing QoS and optimizing resource utilization are conflicting objectives and require a trade-off. We a...

The paper presents a new type of parallel router architecture based on a combinatorial arrangement of routing processing elements. The suggested approach reveals some properties of combinatorial designs, useful for economical implementation of parallel routing. In particular, such an architecture has explicit advantages for packet switching and multicast routing implementation. Key-Words: packe...

An ad hoc network is comprised of mobile hosts without any wired infrastructure support. The primary concerns in ad hoc networks are bandwidth limitation and unpredictable dynamic topology. Therefore, efficient bandwidth utilization is crucial in routing protocols. Reliable multicast plays a significant role in many applications of mobile ad hoc networks (MANETs). The on-demand multicast routin...

Many applications in network consisting of scattered interactive method, software improvements and replica model for distributed database envisages optimized routing, scheduling and data dispersal schemes. A large wireless ad-hoc network broadcast messages from the source to all the elements in a multicast group. Certain research works based on the leader election model (DSLE) focus on the ince...

In this paper we investigate the dynamic multi cast routing problem for single rate loss networks and brie y discuss the dynamic multicast rout ing algorithm called Least Load Multicast Rout ing LLMR We propose a new multicast routing algorithm called Maximum Mean Number of New Calls Accepted Before Blocking Multicast Routing MCBMR which can more accurately re ect the current and future loading...

Opportunistic Routing (OR) has been proposed to improve the efficiency of unicast protocols in wireless networks. In contrast to traditional routing, instead of preselecting a single specific node to be the next-hop forwarder, an ordered set of nodes (referred to as candidates) is selected as the next-hop potential forwarders. In this paper, we propose a new multicast routing protocol based on ...

This paper presents a thorough survey of current work addressing energy efficient multicast routing protocols in Mobile Ad hoc Networks (MANETs). There are so many different issues and solutions which witness the need of energy management in ad hoc wireless networks. The goal of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receivers of a...
