Mobile infostation network is proposed as a new network paradigm to provide users with wireless data services, and a good tradeoff between the connectivity requirement and economic investment can be achieved. Mobile infostation network can offload delay-tolerant traffic from cellular network leaving more resource for mobile real-time applications. Under the mobile infostation network architecture,...
Mobile infostation networks which achieve content distribution by exploiting the opportunistic contact among mobile users (MUs) and access points (APs) have attracted a lot of attention in the last few years. It is found that cooperation either between APs or MUs has a great impact on the network performance. However, in most of the existing works wherever cooperation is involved, cooperation among...
