Efficient multicast routing in wireless mesh networks connected to internet

Abstract

Wireless Mesh Networks (WMNs) have emerged as one of the new hot topics in wireless communications. They consist of a number of static wireless routers which form an access network for end users to IP-based services. Unlike traditional WLAN deployments, wireless mesh networks provide multihop routing, facilitating an easy and cost-effective deployment. In this paper, we focus in the provision of efficient multicast routing on such wireless mesh networks, and its seamless interconnection to wired IP multicast services. The proposed architecture and protocols allow for a ready deployment without changes on the existing networking equipments in the fixed network or in end user's devices. Our simulations and emphirical evaluation on a real wireless mesh network demonstrate that the proposed approach offers a good performance and is highly scalable.
