Efficiency Analysis on QoS Multicast Routing Protocols Under Cross-Layer Approach With Bandwidth Estimated Admission Control

In wireless ad hoc networks, nodes are expected to be heterogeneous with a set of multicast destinations greatly differing in their end devices and QoS requirements. This paper produces an analysis for efficiency for multilayered video multicast over heterogeneous wireless ad hoc networks for bandwidth requirements with admission control. The algorithm used for analysis is Multiple Steiner Minimum Tree (MSMT) and ratio metric constraints for figuring the percentage levels. Moreover, the capacities of nodes in the network and the bandwidth of each link are considered. In order to increase user satisfaction for a group of heterogeneous destinations, different types of multiple multicast trees policy are exploited.
