With the rapid advance in the technology area of data storage, storage capacities have increased substantially while the price has been dropping fast. Motivated by this trend, it has been proposed in the Cache-and-Forward architecture that storage is incorporated into each intermediate CNF router. Content can be cached at CNF routers when they flow through the network, and therefore, routers can serve...
In this paper, we consider an opportunistic access to the spectrum resources in wireless networks. The resources are adopted by the network nodes in a distributed manner, i.e. based on their local channel quality information. The competition of nodes for available resources is modeled as a game. To coerce the desired behavior of the competitors having no information on the other players, pricing (taxation)...
Radio Resource Management(RRM) has become critical with the current growth in the development of new technologies and services in the field of cellular communications. Efficient management of available radio resources and the possibility of dynamically selling unused spectrum are crucial challenges for the telecom operators. We propose an auction model for efficiently marketing radio resources and...
This paper considers distributed protocol design for resource allocation (RA) problems. We propose a fully decentralized RA scheme based on the min-sum message passing (MP) approach in which each message is the solution of small distributed allocation problems. Due to the presence of cycles in the network graph, the MP routine may not converge to a fixed point. To this end, we introduce a reweighted...
