Previous works on multicast capacity mainly focus on deriving asymptotic order results in large-scale wireless networks. While they can explore the general scaling laws of throughput capacity, it is also of great interest for practical concern to predict the exact achievable throughput in networks with an arbitrary finite number of nodes. In this paper, we investigate the nonasymptotic throughput...
Previous works on multicast capacity mainly focus on deriving asymptotic order results in large-scale wireless networks, which can explore the general scaling laws of throughput capacity but cannot predict the exact achievable throughput. In this paper, we investigate the non-asymptotic capacity of multihop wireless networks for multicast applications wherein for each source node, k nodes are randomly...
Video delivery in TV White Space (TVWS) is a challenging task due to the variation of the spectrum availability in TVWS and the stringent bandwidth requirements of video streaming. Most existing frameworks employ an opportunistic spectrum access style which result in bandwidth inefficiency since only one spectrum hole in white space can be used. In this paper, we propose a bandwidth efficient white...
Cognitive radio is an exciting emerging technology that has the potential of dealing with the urgent requirement and scarcity of the radio spectrum. Although having multiple radio interfaces and available spectrum bands can generally increase the effective throughput, a problem arises as to what the best strategy to dynamically assign available bands to secondary users for maximizing throughput by...
