Wireless caching has been used to improve network performance and reduce bandwidth and energy consumption. In this paper, we study the issue of joint admission control and content caching for wireless access points with energy harvesting capability. Given limited energy supply, the access points, in a competitive environment, aim to maximize their payoff defined in terms of revenue by optimizing their...
Attribute-Based Encryption (ABE) is a public key encryption scheme that allows users to encrypt and decrypt messages based on user attributes. In this paper, we consider the problem of constructing a ciphertext-policy attribute-based encryption (CP-ABE) scheme in a setting where the attributes distributor is also the owner of messages that are to be encrypted and shared. The CP-ABE scheme we propose...
Even though demand response of datacenters recently has received increasing attention due to huge demands and flexible power control knobs, most of current studies focus on the owner-operated datacenters, leaving behind another critical segment of datacenter business: multi-tenant colocation. In colocation datacenters, while there exist multiple tenants who manage their own servers, the colocation...
With the increasing popularity of data services and applications, data center networks have been introduced to serve users in a centralized fashion. Furthermore, the flexibility of the data service subscribers' (DSSs') requirements motivates data center virtualization so as to optimize the resource allocation among all DSSs. However, as the massive data centers are usually far away from the DSSs,...
