In this chapter we focus on cooperative strategies for IP-services over DVB-H networks to save energy. It demonstrates the potential of non-altruistic cooperation between mobile devices. The envisioned cooperation is based on cellular reception of DVB-H data, which is then shared among mobile devices within each others’ proximity over short-range links. The short-range communication is realized by Bluetooth, where a cross-platform design approach is introduced to optimize the signalling communication in the Bluetooth system. Three different cooperative algorithms are designed for the short-range link (Bluetooth) communication. Numerical results show that a energy saving of over 50% can be achieved by cooperative networking of three mobile devices in fully cooperating mode.
