An emerging requirement for 5G systems is the ability to provide wireless ultra-reliable communication (URC) services with close-to-full availability for cloud-based applications. Among such applications, a prominent role is expected to be played by mobile cloud computing (MCC), that is, by the offloading of computationally intensive tasks from mobile devices to the cloud. MCC allows battery-limited...
Cellular networks are evolving toward dense deployment of small cells, which requires flexible and efficient backhauling solutions. A viable solution that reuses the same spectrum is wireless backhaul where the small base station acts as a relay. In this letter, we consider a reference system that uses wired backhaul, and each mobile station in the small cell has its uplink and downlink rates defined...
Consider a wireless network with multiple sources and destinations, where the amount of data of each source node is finite. An interesting question is what is the shortest completion time, i. e. the time required that all data from the sources gets to the respective destinations. A similar question arises for the minimal required energy. While the requirement for minimal energy consumption is obvious,...
