This paper develops a feasible architecture for endto-end QoS management over B3G networks where multiple heterogeneous radio access networks (RAN) can be coordinated at radio lev...
—We consider a cognitive radio network with distributed multiple secondary users, where each user independently searches for spectrum opportunities in multiple channels without e...
—Cooperative communications leverages the spatial diversity available in a wireless network enabling multiple radio nodes work together to improve the overall system performance....
Long-distance multi-hop wireless networks have been used in recent years to provide connectivity to rural areas. The salient features of such networks include TDMA channel access, ...
Abstract—We consider a cognitive radio network where multiple secondary users (SUs) contend for spectrum usage, using random access, over available primary user (PU) channels. Ou...
