ab: Summary: In wireless ad hoc networks there is no fixed infrastructure or
    centralized controller to enforce cooperation between nodes. Therefore,
    nodes may act selfishly in running network protocols for conserving
    their own energy resources. In this paper, we consider the "topology
    control (TC) game" as the problem of creating an energy-efficient
    topology in wireless ad hoc networks in the presence of selfish nodes.
    We define a new TC game in which nodes are able to dynamically adjust
    their transmission power in a per-packet manner, and try to minimize
    their energy usage through considering both traffic load and
    transmission power parameters. After analyzing the problem, we propose
    several algorithms to find stable topologies in an environment composed
    of selfish nodes, using two types of global and local connectivity
    information. Finally, we evaluate the performance of the proposed
    algorithms by simulations. Our simulation results show that using
    appropriate local information can interestingly result in more
    efficient topologies than global information.
