In this paper, we propose an energy-efficient on-demand multicast routing protocol (EMP) for wireless ad hoc and sensor networks. The design objective is to prolong the network lifetime of such networks. For this purpose, EMP introduces the strategy of energy critical avoidance in the process of ondemand construction of multicast routing trees. That is, those energy-critical nodes in the network are...

Cognitive radio networks (CRN) have emerged as a promising, yet challenging, solution to enhance spectrum utilization, thanks to the technology of cognitive radios. In this work, we consider the multicast routing and channel allocation problem in cognitive radio mesh networks. Due to the potential heterogeneity in channel availability among mesh routers (MRs) and the frequency switching latency, end-to-end...
