A New Approach for Time Synchronization in Wireless Sensor Networks: Pairwise Broadcast Synchronization
TLDR
An energy-efficient clock synchronization scheme for Wireless Sensor Networks (WSNs) based on a novel time synchronization approach which significantly reduces the overall network-wide energy consumption without incurring any loss of synchronization accuracy compared to other well-known schemes.

Energy Efficient Resource Allocation for Mixed RF/VLC Heterogeneous Wireless Networks
TLDR
This paper forms and solves the problem of power and bandwidth allocation for energy efficiency maximization of a heterogeneous network composed of a VLC system and an RF communication system, and investigates the impact of the system parameters on the energy efficiency of the mixed RF/VLC heterogeneity network.

Performance Analysis of a Power Limited Spectrum Sharing System With TAS/MRC
TLDR
Asymptotic performance analysis of the MCS-TM-NI reveals that TAS/MRC in a MIMO cognitive system achieves a generalized diversity gain equal to the product of the number of transmit and receive antennas. Expand
Exact Performance Analysis of MIMO Cognitive Radio Systems Using Transmit Antenna Selection
TLDR
Numerical results in a Rayleigh fading environment manifest that the MV-based scheme outperforms the CSI- based power allocation strategy provided that a low interference power constraint is deployed, implying thatThe MV- based scheme is more suitable for practical systems. Expand
A Survey on Green Mobile Networking: From The Perspectives of Network Operators and Mobile Users
TLDR
This survey mainly focuses on energy-efficient techniques in base stations and mobile terminals as they constitute the major sources of energy consumption in wireless access networks, from the operator and user perspectives, respectively. Expand
Outage Analysis for Underlay Cognitive Networks Using Incremental Regenerative Relaying
TLDR
An underlay cognitive network where the quality of service (QoS) of the secondary link is maintained by triggering an opportunistic regenerative relaying once it falls under an unacceptable level is investigated. Expand
On Maximum Likelihood Estimation of Clock Offset and Skew in Networks With Exponential Delays
TLDR
A simple, computationally efficient and easy to implement algorithm is presented as an alternative to the ML estimator which particularly suits the low power demanding regime of wireless sensor networks. Expand
A survey on energy trading in smart grid
TLDR
An overview of distributed energy trading concepts in smart grid, identifying the motivation and the desired outcomes of energy trading framework, and presenting the enabling technologies that are required to generate, store, and communicate with the trading agencies. Expand
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
TLDR
A secondary relay selection scheme which maximizes the end-to-end signal to noise ratio (SNR) for the secondary link while keeping the interference levels to the primary network below a certain threshold is proposed. Expand
Best relay selection using SNR and interference quotient for underlay cognitive networks
TLDR
A relay selection scheme which uses the quotient of the relay link signal to noise ratio (SNR) and the interference generated from the relay to the primary user to choose the best relay to be feasible in low SNR regions. Expand
