QoS Aware Multicast Routing In Wireless Mesh Network

Motivation and Need

Wireless mesh networks are widely discussed as an enabling technology of fourth generation access solution. They are cheap, quickly deployable, power efficient as well as auto-configured and self-healed. Along with these features, providing multimedia services is one of the key responsibilities of WMNs which is challenging due to highly unpredictable and lossy medium characteristics, bandwidth constraints and demand of best effort (BE) services along with real-time services. Also, a new paradigm is recently added to portfolio of responsibilities of WMNs i.e. multicasting of QoS oriented applications. Also, it is worth mentioning that due to technological maturity and wide range availability, 802.11 and 802.16 standards of IEEE have gained much importance as last mile solution. This paper briefly describes characteristic architecture of WMNs, the challenges they face towards provisioning of QoS to the end user. Afterwards this paper includes a proposed roadmap towards designing of a real world, QoS oriented WMN protocol. Then, the paper reviews recent works on provisioning of QoS oriented applications, both in uncast and multicast. Also, this paper discusses improvements suggested to make IEEE 802.11 and 802.16 based networks a frontier in the domain of WMNs also.

Current Progress

Gateway registration, QoS aware route tree building and multicasting over the wireless mesh network.
