Centralized resource allocation in large scale wireless network results in heavy network overload which indicates us to use resource solution in distributed manner using locally available information to individual users. In such scenario, game theory is regarded as an optimization tool for distributed resource allocation in wireless networks. Players, which are active users in wireless networks, change their strategies based on the wireless environment in which they operate. After few steps, each player would reach to socially optimal point called Nash equilibrium at which no players would be benefited by deviating its own strategies. Furthermore, resource allocation in wireless systems using game is scalable and easy to measure the performance.  

My research focus in this area are to investigate the algorithms

  • To perform interference mitigation in multi-user wireless systems with QoS constraints.
  • To perform dynamic adaptation of transmission parameters (power, transmission rate, channel)
  • To perform social optimal resource allocation.
