Game approach for access point selection and bandwidth allocation in co-existing WBANs

Widespread use of wireless body area networks (WBANs) has led to the deployment of dedicated access points (APs) to serve them. An increased traffic load at an AP can degrade the performance of all associated WBANs. To resolve this issue, deployed APs should judiciously invest in the available bandw...

Description
Summary:Widespread use of wireless body area networks (WBANs) has led to the deployment of dedicated access points (APs) to serve them. An increased traffic load at an AP can degrade the performance of all associated WBANs. To resolve this issue, deployed APs should judiciously invest in the available bandwidth. We model the WBAN-AP interactions as a multi-leader multi-follower Stackelberg game. The multi-leader game is a non-cooperative game, in which each AP decides its bandwidth to maximize its own profit. The multi-follower game is an evolutionary game, in which each WBAN decides which AP can provide the best QoS at the least cost. The game models are evaluated to verify the effectiveness of our approach.
