    Capacity and Fairness Analysis of Game Theoretic Power Controlled Wireless Access Network 

    Katan Vattanaviboon; Patrachart Komolkiti; Chaodit Aswakul (2013)

    In wireless networks, transmission power has adverse effects. With low transmission power, the received signal may be eclipsed by the noise and interference from other transmitters, resulting in low SINR. On the other hand, with high transmission power, the interference seen at other receivers could be too large, also resulting in low SINR. This paper aims to address this problem by using the game theory. Particularly, the scenario of wireless access network with two transmitters, each with two intended receivers, is considered. Selection of ...

    Improved Bandwidth Allocation In Cognitive Radio Networks Based on Game Theory 

    Bhattarai, Amulya; Patrachart Komolkiti; Chaodit Aswakull (2013-05)

    In this paper, an improved method for bandwidth allocation in a Cognitive Radio Network based on game theory is presented. In this work, utility has been modified by inserting weights to the three terms, received power, interference to other links and interference from other links. Inserting weights enables us to treat different CRN scenarios separately and appropriately as per the requirement of the administrator. Moreover, a suitable performance index for a CRN that considers throughput and interference to other links has been introduced ...
