ABSTRACT
This chapter presents the Demanding-Based Resources Trading model for Green Communications. For wireless access networks, which cost significant energy in wireless communications, a great deal of work has been done for reducing the energy consumption. According to wireless networks resources trading relationships, different wireless resources can be consumed to meet the same set of quality-of-service (QoS) performance metrics. The guaranteed QoS performance achieved by consuming one type of resource can also be obtained by consuming different types of resources. For wireless networks, available resources can be classified into the following five categories: time, bandwidth, space, energy, and code. For green wireless networks, the goal of resource trading is to consume the minimum energy resource for the required QoS performance. The chapter aims to use the bandwidth resource trading for energy saving in macro-femto cellular networks. In two-tier macro-femto cellular networks, the first tier and second tier are macrocells and femtocells, respectively.
