Energy-Efficient Caching for Mobile Edge Computing in 5G Networks
Mobile Edge Computing (MEC), which is considered a promising and emerging paradigm to provide caching capabilities in proximity to mobile devices in 5G networks, enables fast, popular content delivery of delay-sensitive applications at the backhaul capacity of limited mobile networks. Most existing studies focus on cache allocation, mechanism design and coding design for caching. However, grid ...
متن کاملEdge-Caching Wireless Networks: Energy-Efficient Design and Optimization
Edge-caching has received much attention as an efficient technique to reduce delivery latency and network congestion during peak-traffic times by bringing data closer to end users. Existing works usually design caching algorithms separately from physical layer design. In this paper, we analyse edge-caching wireless networks by taking into account the caching capability when designing the signal...
متن کاملProactive Caching for Hybrid Urban Mobile Networks
Consuming digital multimedia (such as videos) on move has become evermore popular, all thanks to the widespread success of powerful, networked handheld devices as well as availability of 3G services in urban areas. The storage sizes and Wi-Fi networking capabilities of such devices have made them a good platform for opportunistic content sharing; however given the bulky nature of multimedia fil...
متن کاملA Heuristic Approach for K-Coverage Extension with Energy-Efficient Sleep Scheduling in Sensor Networks
In this paper we consider the problem of coverage in a wireless sensor network where nodes already have been previously deployed. Our goal is to design an efficient strategy to add further nodes for achieving a certain target K-coverage throughout the entire monitoring region. A heuristic approach based on a dynamic model resembling gas bubbles is applied to solve this problem. Once the additio...
متن کاملGreen Wave: Latency and Capacity-Efficient Sleep Scheduling for Wireless Networks Technical Report
While scheduling the nodes in a wireless network to sleep periodically can save energy, it also incurs higher latency and lower throughput. We consider the problem of designing optimal sleep schedules in wireless networks, and show that finding sleep schedules that can minimize the latency over a given subset of source-destination pairs is NP-hard. We also derive a latency lower bound given by ...
