Energy Saving in Multi-Standard Mobile Terminals Through Short-Range Cooperation

Free registration required

Executive Summary

Multi-standard mobile devices are allowing users to enjoy higher data rates and ubiquitous connectivity. These advances are achieved on the expense of higher energy consumption requirements due to the continuous connectivity and the multiple active wireless interfaces. In this paper, the authors use one advantage of the multiple interfaces, namely Short-Range (SR) communications. Mobile Terminals (MTs) use SR cooperative networking to take advantage of the good channel quality of SR links to save energy in multi-standard MTs. In this cooperative network, the combined energy of all MTs is treated as a pool of resources, which is used by all MTs in the network. Towards this end, they propose using cooperation between MTs using SR technology to achieve energy savings.
