HIMAC: Hybrid and Integrated Multicast Admission Control

Providing multicast admission control in ad hoc networks is extremely challenging. In this proposal, we present a hybrid and integrated multicast admission control (HIMAC) mechanism to address this challenging problem. In essence, we propose some novel approaches to address some fundamental problems in ad hoc networks. In the proposed solution, we adopt hybrid methods to estimate the available bandwidth of different types of networks. We propose a measurement-based approach to estimate the available bandwidth for backbone networks and a model-driven approach for ad hoc networks. Both of these approaches are light–weight, non-intrusive and accurate in the targeted networks. In order to make the model-based bandwidth estimation approach work correctly in ad hoc networks, we propose a novel approach to model the effect of wireless interference on loss rate. This model overcomes the limits of existing works and is feasible for real networks. Moreover, this model, in conjunction with the efficient and comprehensive inference method proposed in our solution, derives an accurate and realistic interference pattern for real networks.
