Protecting private cloud located within public cloud
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Many studies use cryptographic technologies to protect sensitive data in public cloud. However, these approaches may introduce large overheads. Recently, hybrid cloud started to gain a lot of attentions. A hybrid cloud ...
Battery status-aware authentication scheme for V2G networks in smart grid
(2013 , Article)
Vehicle-to-grid (V2G) is emerging as an attractive paradigm in smart grid, and provides power and information services by periodically collecting power status of battery vehicles (BVs). During a BV's interaction with power ...
Incentive scheduler algorithm for cooperation and coverage extension in wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
In this paper, we focus on wireless coverage extension and nodes' cooperation. We propose a new protocol based on an incentive approach and a scheduling algorithm to reward cooperative nodes. The cost of cooperation can ...

(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
This paper investigates random walk mobility models with location heterogeneity, where different locations may have different neighboring regions.With the assumption of totally n locations, we consider two cases, i.e., ...
Improving macrocell downlink throughput in rayleigh fading channel environment through femtocell user cooperation
(2013 , Article)
This paper studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically derive and evaluate the achievable performance of these ...
Securing vehicle-to-grid communications in the smart grid
(2013 , Article)
Using vehicle-to-grid (V2G) services, battery vehicles (BVs) may help the smart grid alleviate peaks in power consumption. However, wireless communications infrastructure between BVs and the smart grid also introduce severe ...
Impact of channel estimation error on bidirectional MABC-AF relaying with asymmetric traffic requirements
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Article)
Channel estimation error results in severe performance deterioration in wireless networks. In this paper, we study the impact of imperfect channel estimation (ICE) on the outage performance of bidirectional relaying where ...
