Auditing cloud service level agreement on VM CPU speed
( IEEE Computer Society , 2014 , Conference)In this paper, we present a novel scheme for auditing Service Level Agreement (SLA) in a semi-trusted or untrusted cloud. A SLA is a contract formed between a cloud service provider (CSP)and a user which specifies, in ... -
BIRD-VNE: Backtrack-avoidance virtual network embedding in polynomial time
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference)The virtual network embedding (VNE) problem is known to be NP-hard, and as a result, several heuristic approaches have been proposed to solve it. These heuristics find sub-optimal solutions in polynomial time, but have ... -
Joint mode selection, channel allocation and power assignment for green device-to-device communications
( IEEE Computer Society , 2014 , Conference)Device-to-Device (D2D) communication has emerged as a promising technique for improving capacity and reducing power consumption in wireless networks. Most existing works on D2D communications either targeted CDMA-based ... -
Accountable and privacy-enhanced access control in wireless sensor networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)In general, owners and users of wireless sensor networks (WSNs) are different entities. A user may want to hide his/her data access privacy from anyone else including the network owner and, at the same time, users who ... -
