QoS aware multicast using mobile agents technique

Abstract

The significant growths of group communications and QoS aware applications over the Internet have accelerated the development of QoS multicast routing. Recently, many QoS-based multicast protocols have been proposed to meet these requirements. However, the process of changing and deploying theses protocols are lengthy and difficult, because the process requires standardization and automatic mechanism for dispatching programs for new protocols. This paper describes a new agents based multicast QoS routing protocol (MAQMR). This approach, first, allows the multicast protocol to be implemented within mobile agents and dynamically deployed at every node the agent is visiting. Second, independently of unicast routing, mobile agents act in parallel and distributed fashion cooperate in order to construct the multicast tree while minimizing message overhead and satisfying QoS requirements. © Springer-Verlag Berlin Heidelberg 2004.
