Rate Adaptation in Ad Hoc Networks Based on Pricing
Nodes in ad hoc networks are autonomous and self-configuring with no form of centralized administration such that nodes are free to selfishly optimize their individual utilities without considering utilities of other network users. This compels users to transmit at high power leading to abnormal interference in the network hence degrades network performance (i.e. low data rates, loss of connectivity among others). In this paper, the authors propose Rate Adaptation based on Pricing (RAP) algorithm that incorporates penalty (pricing) obtruded to users' choices of transmission parameters to curb the self-interest behaviour.
