E cient group communication within the Internet has been implemented by multicast. Unfortunately, its global deployment is missing. Nevertheless, emerging and progressively establishing popular applications, like IPTV or large-scale social video chats, require an economical data distribution throughout the Internet. To overcome the limitations of multicast deployment, we introduce and analyze B...

We consider efficient communication schemes based on both network-supported and application-level multicast techniques for content-based publication-subscription systems. We show that the communication costs depend heavily on the network configurations, distribution of publications and subscriptions. We devise new algorithms and adapt existing partitional data clustering algorithms. These algor...

Mobile ad hoc network is an autonomous system of mobile nodes characterized by wireless links. The major challenge in ad hoc networks lies in adapting multicast communication to several environments, where mobility is unlimited and failures are frequent. Reliable multicast delivery requires a multicast message to be received by all mobile nodes in the communication group. The recovery mechanism...

Many tree-based multicast algorithms have been proposed to provide an eecient software implementation on parallel platforms without hardware multicast support. These algorithms are either architecture-dependent (not portable) or architecture-independent (portable) but do not provide good performance when porting to diierent parallel platforms. Based on the LogP model, the proposed parameterized...

Many emerging commercial and military applications require secure multicast communication in adhoc environments. Secure multicast communication in mobile adhoc networks is challenging due to its inherent characteristics of infrastructure-less architecture with lack of central authority, high packet loss rates and limited resources such as bandwidth, time and power. Hence key management is the f...

Wireless mesh network (WMN) is used to develop techniques for guaranteeing end-to-end delay performance over multihop wireless communication networks. The aim of WMN is to provide seamless communication in large heterogeneous networks and between heterogeneous devices. According to the architecture of WMN, mesh cloud will allow scaling the network easily. Hence we are addressing WMNs as scalabl...

MANET is a self organized network and is composed of various independent nodes connected in an arbitrary fashion. Communication over a MANET network basically occurs through some different types of communication, such as unicast and multicast. Our work is generally been focusing on two of the protocols i.e. unicast and multicast routing protocols AODV and PUMA respectively. We will be comparing...

Scalability is one of the most important requirements for secure multicast in a multi-group environment. In this study, we propose a decentralized multi-group key management scheme that allows each multicast group sender to control the access to its group communication independently. Scalability is enhanced by local rekeying and inter-working among different subgroups. The group key secrecy and...

Providing key management schemes for large scale multicast groups has become a bottleneck due to many potential commercial applications on Internet such as stock quote and software distribution. For secure multicast communication, all the group members share a common key called as Secret Group Key. Since the member dynamics such as join or leave do not necessarily terminate the multicast sessio...

Multicast is a very efficient technology in one-to-many communication scenarios. With the popularity of mobile devices, and demanding group information exchange, multicast in mobile ad hoc networks attracts much research attention. This paper reviews the state-of-art multicast protocols and classifies them into two categories: tree-based and mesh-based. We review one classic protocol closely fo...
