In this paper, we analyze the advantages of multi-access (MA) systems in heterogeneous networks, where a mobile station (MS) can simultaneously access different non-interfering networks with different radio access technologies (RATs). For this analysis, we consider the following problem: How many RATs should the MS connect to? First, the beneficial aspects of MA is demonstrated by a simplified example,...
Today, we are in a world where several radio networks arise: we speak about mobile networks, wireless networks (IEEE 802.11, .15, .16, .20, .21...), networks of sensors, radio-frequency identification networks (RFID) and more generally networks of ldquoThings connected via radio interfacerdquo. In this heterogeneous environment, a user with a multi-interface terminal can have access to the networks...
In this paper, in order to guarantee QoS of CAC for four classes of new calls (i.e., conversational service, streaming service, interactive service, and background service with distinct QoS requirements are considered , which defined by 3GPP). We first propose a mechanism design framework based on VCG mechanism for CAC, we model the CAC problem as a game played among four classes of new calls. Importantly,...
