Cooperative Content Distribution over Wireless Networks for Energy and Delay Minimization

Content distribution with mobile-to-mobile cooperation is studied. Data is sent to
mobile terminals on a long range link then the terminals exchange the content using
an appropriate short range wireless technology. Unicasting and multicasting are
investigated, both on the long range and short range links. Energy minimization is
formulated as an optimization problem for each scenario, and the optimal solutions
are determined in closed form. Moreover, the schemes are applied in public safety
vehicular networks, where Long Term Evolution (LTE) network is used for the long
range link, while IEEE 802.11 p is considered for inter-vehicle collaboration on the
short range links. Finally, relay-based multicasting is applied in high speed trains for
energy and delay minimization. Results show that cooperative schemes outperform
non-cooperative ones and other previous related work in terms of energy and delay
savings. Furthermore, practical implementation aspects of the proposed methods are
also discussed.
