Having an effective technique for bandwidth allocation is very important in wireless communications. Artificial Immune Systems, a relatively new meta-heuristic for solving optimization-related problems, is investigated in this study to design a cellular channel allocation framework. In this study, mobile hosts are allowed to continue interacting with the cells that they are currently in, even when...
In this paper, we present a novel cooperative resource management mechanism in mobile cloud computing environment. This mechanism is based on cooperation between mobile devices using their short range radio technology such as WiFi with the goal of maximizing the revenue of the cellular service provider. Users with poor cellular link quality connect with nearby devices through their WiFi interface...
Device-to-device (D2D) connectivity is likely to represent a major enabling technology for future fifth generation (5G) radio access networks. In this paper, we introduce a new model for device cooperation in 5G radio access networks termed frequency-selective soft forwarding (FSSF). FSSF is based on soft-combining by a target user equipment (TUE) of selectively forwarded soft information data by...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
In this paper, we consider a new channel probing scheme for opportunistic scheduling in the uplink of orthogonal frequency division multiplexing (OFDM)-based wireless systems. To reduce signaling overhead for the probing, we consider a two-step channel probing process; called pre-probing and mainprobing. Good subchannels are first estimated through the pre-probing process using a probing signal transmitted...
