Multicast support is critical and a desirable feature of multi-radio wireless mesh networks. However, the nature of wireless network, i.e. broadcasting and interference, makes it a challenge to efficiently support multicast services. In this paper, we study how to build a multicast structure with maximum average throughput in terms of minimum transmission time and channel interference in a multi-radio...
Half duplex devices are widely used in today's wireless networks. These devices can only send or receive, but not do both at the same time. In this paper, we use cooperative decode-forward relay strategies to increase the throughput of half-duplex wireless networks. Due to the half duplex constraint, relays need to carefully choose their transmission states in order to maximize the throughput. We...
The capacity of multi-channel multi-hop network can be substantially increased by equipping each node with multi-radio which allow for simultaneous transmission, but there are still much interference between those transmission links without appropriate channel assignment due to limited non-overlapping channels, so further optimization is need to carefully assign channel for radios. This paper considers...
Cognitive radio makes it possible for an unlicensed user to access a spectrum unoccupied by licensed users. Efficient subcarricr and power allocation algorithm in CR networks is a challenging problem, especially for uplink. In this paper, an efficient multiuser water-filling algorithm is proposed under the interference temperature constraints. L'sing this algorithm, subcarriers are allocated to the...
