It is very challenging to implement the envisioned beyond 3G and 4G based on the conventional cellular network architecture. So a central controlled peer-to-peer network architecture is proposed, which is based on the cooperation of
coexisting heterogeneous wireless networks. In the advocated architecture, the mobile terminal is capable of cellular reception of data which is then forwarded or shared among mobile devices within each others’ proximity over the short-range link.
Several cooperative network demonstrators have illustrated the great potential of cooperative networks. It is en emerging trend that coexisting heterogeneous wireless networks will evolve to cooperate with each other to facilitate the centrally controlled
P2P cooperative networks
