摘要:SUMMARY(#br)In cognitive radio networks, Secondary Users (SUs) can access the spectrum simultaneously with the Primary Users (PUs) in underlay mode. In this case, interference caused to the licensed users has to be effectively controlled. The SUs have to make spectrum access...

摘要:The solution we propose optimizes the energy inside the wireless sensor network (WSN) with higher performance. The WSN is composed of many sensors nodes which collect the information, treat that information then send it to the base station. The information is received by the base...

摘要:WiFi traffic offloading is becoming especially appealing because of the upcoming ultra-dense cellular networks. However, WiFi offloading decision as well as WiFi-Access Points (W-AP) selection should be carefully studied in order not to affect the offloaded users’ experience...

摘要:In this paper, we investigate subcarrier assignment in downlink multi-cell Orthogonal Frequency Division Multiple Access (OFDMA) systems. As user bit rates are in continuous increase, the limitation of the available spectrum requires more and more efficient subcarrier assignment ...
