This paper introduces an implementation of The Extensible Messaging and Presence Protocol (XMPP) based on cloud service message push technology through an instance which explains the implementation procedure. Specifically, Android client establishes XMPP connection and registration through cloud service, the cloud server could actively push messages to user's Android devices based on their demands,...
In this investigation, we propose and investigate the standard WiMAX access in high speed railway (HSR) using radio over fiber (RoF) link. We also discuss the theory of mobile WiMAX at a target speed of 300 km/hr in simulation. We also analyze the effect of the Doppler frequency shift over HSR. The effective transmission fiber length in the WiMAX-RoF system was limited due to the time-division-duplex...
In the future mobile systems, various wireless access technologies will exist simultaneously and constitute a complicated heterogeneous networks environment. Considering the users' services satisfaction, a novel network selection algorithm based on dynamic weight setting is proposed in order to solve the existing problems that there is not a tradeoff between users' preferences and network conditions,...
