Abstract：Convergence and cooperation of heterogeneous networks were widely discussed recently. An energy saving strategy of cooperative data reception in cellular link and the cooperative transmitting between mobile terminals over multi-hop short range link is introduced to achieve energy saving in DVB-H network. The performance of energy saving is significantly improved while the node will cooperate with more nodes in the piconet. Up to 54% power saving can be achieved in a three node piconet according to the simulation. Up to 7.6% more gains for the whole cooperation piconet compared with the previous cooperative strategy under the same scenario.
