The demands for wireless network bandwidth are rapidly increasing with the expanding number of mobile users as well as the diversification in types of services. Although fast-developing communication techniques continue to enlarge the network capacity, the growth rate of the huge amount of users' demands still outstrip the gains. Learning from the information cognition process of human brains, we...
This paper investigates QoS-aware relay selection and subcarrier assignment in cooperative OFDMA networks. In contrast to some existing works, which solve the sum-rate maximization problem directly, we first simplify it by exploiting the structure of the optimal solution, then we solve the simplified problem. To characterize the optimal network sum-rate performance, we solve the simplified problem...
Effectively use of intelligent transport system (ITS) can not only improve vehicular safety but also enhance the efficiency of current transport system and driving comfort. The key point of ITS is how vehicles communicate with each other, which means we need a set of communication protocols to facilitate moving vehicles. For this reason, IEEE developed WAVE (Wireless Access in Vehicular Environment)...
