Device-to-device (D2D) content sharing holds great promise to alleviate the growing strain on cellular networks, as it offloads popular content data onto direct peer-to-peer links. However, it is still largely unexplored how content sharing could benefit from utilizing multi-hop rather than conventional single-hop D2D communications. As a step towards this end, this paper proposes a generalized two-level...
In Mobile Peer-to-Peer networks (MP2P), the network state information is difficult to measure accurately, and application requirement on quality of service (QoS) and trust is also hard to exactly express. Therefore, trust QoS routing scheme should be based on the fuzzy information. In this paper, we propose a trust QoS routing scheme based on interval matching. It applies the interval form to denote...
Traffic problem in mega-events has gained more and more research attentions from OR community. In this paper, a special transit route designing problem is investigated, which aims to design additional routes to satisfy the special travel demand in mega-events. A mix 0–1 integer programming model is formatted firstly and then a hybrid genetic algorithm is proposed to solve the investigated problem...
