To meet the explosive demand on delivering high-definition video steams over cellular networks, we design a <bold>So </bold>cial-aware video multi<bold>Cast</bold> (SoCast) system leveraging device-to-device (D2D) communications. One salient feature of SoCast is to stimulate effective cooperation among mobile users (clients), by making use of two types of important social ties,...
The device-to-device (D2D) channels allow content sharing when two devices are in close proximity, which can help improve resource utilization and network capacity. The data caching is introduced in D2D networks to enable the quick data access in mobile networks. Due to the selfish nature of users, they wish to get as much replication as possible in the opportunistic connections, seeking to maximize...
In this paper, we propose SoCast — a cooperative video multicast framework to stimulate effective cooperation among mobile users (clients), by leveraging two types of important social ties, i.e., social trust and social reciprocity. By using SoCast, clients can form groups to restore incomplete video frames by obtaining missing packets from other clients, according to the unique video encoding structure...
It is hard to solve the problem well of large-scale water resource system of multi-water resources and multi-users with traditional planning method. The Multi-Objective Genetic Algorithms (MOGA) on a rank-based fitness is put forward in this paper according to inherent parallel mechanism and overall optimization characters of Genetic Algorithms. We model the problem of optimal allocation of water...
In order to enhance the supporting capacity of military logistics distribution system under attack, according to its characteristic multiple covering, a model was designed for allocating limited protection resources to q of p existing facilities. The model was formulated in a bilevel programming, whose upper level maximized the extent of protected facilities covering customers when enemy destroyed...
Geographic information system (GIS) has gotten extensive application in water resource management, except in water resource allocation. By analyze the research content, principle and method of water resource allocation, the data management and analysis function of GIS is helpful to build water resource allocation decision support system. As the water resource allocation of Hebei province configure...
Selective order acceptance and capacity allocation policies are vital to the success of make-to-order (MTO) manufactures. The importance of these two policies has been acknowledged both in manufacturing industry and academic research. After the huge success of revenue management in retail and service industries, there are more and more MTO manufactures introducing revenue management techniques into...
