Design and analysis of an improved smartcard-based remote user password authentication scheme
With the fast development of the Internet and the telecommunication technologies, internet users are carrying out various electronic transactions over internet by means of the authentication protocols. To ensure efficient and robust online transaction, ...
A comprehensive DCF performance analysis in noisy industrial wireless networks
The use of wireless technology in industrial networks is becoming more popular because of its flexibility, reduction of cable cost, and deployment time. Providing an accurate model to study the most important parameters of these networks, the timeliness ...
Access control mechanism using flexible multi-layer structure for mesh-based P2P live streaming systems
When thousands of new peers seek to join the peer-to-peer P2P system within a very short time i.e., the so-called flash crowd event, most of the peers suffer a long startup delay as a result of peer over-competition. Accordingly, recent studies have ...
Performance of cognitive relay network with novel hybrid spectrum access schemes with imperfect CSI
Two novel spectrum access schemes, a hybrid spectrum access scheme HSAS and a modified HSAS combining underlay mode and overlay mode, are proposed for a relay based cognitive radio CR network. The CR employs the underlay mode with imperfect channel ...
Achievable sum-rate maximization using relay/antenna selection for MIMO two-way AF relaying with channel uncertainties
This paper focuses on the layered relay-and-antenna selection LRAS for achievable sum-rate ASR maximization while considering the impacts of residual self-interference due to channel estimation errors in multiple-input multiple-output two-way amplify-...
Dynamic multicast link selections for buffer-aided relaying networks
The management of small cell is considered a key point in next-generation cellular networks for providing higher data rates, and the relay nodes are expected to be useful to improve the coverage area. Moreover, multicast services have gained importance ...
The offloading model for green base stations in hybrid energy networks with multiple objectives
Based on green energy prediction and storage, a novel green base station GBS offloading model is proposed and can be employed with multiple objectives in this paper to save energy. By predicting the value of green energy collected by GBS and updating ...
