HYBRID WIRELESS NETWORKS WITH QOD ROUTING PROTOCOL

February 12, 2015 by IeeeAdmin

In order to enhance the QoS support capability of hybrid wireless networks, in this abstract, we propose a QoS-Oriented Distributed routing protocol (QOD). Taking advantage of fewer transmission hops and any cast transmission features of the hybrid networks, QOD transforms the packet routing problem to a resource scheduling problem. QOD incorporates five algorithms: 1) a […]

SECURITY OF TRUSTEE-BASED SOCIAL AUTHENTICATIONS AGAINST FOREST FIRE ATTACK

February 11, 2015 by IeeeAdmin

Trustee-based social authentication has attracted increasing attentions and has been shown to be a promising backup authentication mechanism . Specifically, a user’s security in trustee-based social authentications relies on the security of his or her trustees; if all trustees of a user are already compromised, then the attacker can also compromise him or her because […]

CLOUD COMPUTING WITH SHARED AUTHORITY BASED PRIVACY-PRESERVING AUTHENTICATION PROTOCOL

February 10, 2015 by IeeeAdmin

In our model, privacy is accomplished by encrypting the data it can prevent the un authorized access. We are going to raise the privacy level of the data owner and the confidentiality of the data by providing access to users. Here we proposed the secured system and data owner can decide whether the user can […]

BROKER-LESS PUBLISH/SUBSCRIBE SYSTEMS WITH IDENTITY-BASED ENCRYPTION

February 9, 2015 by IeeeAdmin

In publish/subscribe (pub/sub) communication, Publishers inject information into the pub/sub system, and subscribers specify the events of interest by means of subscriptions. Published events are routed to their relevant subscribers, without the publishers knowing the relevant set of subscribers, or vice versa. This abstract presents a novel approach to provide confidentiality and authentication in a […]

SAPA PROTOCOL FOR CLOUD STORAGE

February 7, 2015 by IeeeAdmin

In this abstract, we propose a shared authority based privacy preserving authentication protocol (SAPA) for the cloud data storage, which realizes authentication and authorization without compromising a user’s private information. The main contributions are as follows. 1) Identify a new privacy challenge in cloud storage, and address a subtle privacy issue during a user challenging […]

STOCHASTIC POWER REDUCTION SCHEME BASED POWER COST REDUCTION IN DISTRIBUTED DATA CENTERS

February 6, 2015 by IeeeAdmin

Geographically distributed data centers are contains a huge number of servers. Our goal then is to minimize power cost by deciding, how to distribute the workload from the front-end servers to the back-end clusters, how many servers to activate at each back-end cluster at any given time; and how to set the service rates (or […]

REDUCING POWER COST USING SAVE ALGORITHM IN DISTRIBUTED DATA CENTERS

February 3, 2015 by IeeeAdmin

In this abstract propose a two-time-scale control algorithm aimed at reducing power cost and facilitating a power cost versus delay trade-off in geographically distributed data centers. By extending the traditional Lyapunov optimization approach, which operates on a single time scale, to two different time scales, we derive analytical bounds on the time average power cost […]

CLOUD BACKUP SERVICES OF PERSONAL STORAGE USING APPLICATION-AWARE LOCAL-GLOBAL SOURCE DEDUPLICATION

February 2, 2015 by IeeeAdmin

Data deduplication, an effective data compression approach that exploits data redundancy, partitions large data objects into smaller parts, called chunks, represents these chunks by their fingerprints (i.e., generally a crypto-graphic hash of the chunk data), replaces the duplicate chunks with their fingerprints after chunk fingerprint index lookup, and only transfers or stores the unique chunks […]
