Improving the efficiency of dye sensitized solar cells by TiO2-graphene nanocomposite photoanode
(
Elsevier B.V.
, 2015 , Article)
Nanocomposite photoanodes were prepared by addition of graphene (GR) micro-platelets to TiO2 nanoparticulate paste. TiO2/graphene based DSSCs were fabricated using Z907 photosensitizer. Transmission electron microscope was ...
Effective area spectral efficiency for wireless communication networks with interference management
(
Springer International Publishing
, 2015 , Article)
In this paper, we introduce a new metric, namely, effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of point-to-point transmission systems and decode and forward ...
Joint Optimization of Area Spectral Efficiency and Delay over PPP Interfered Ad-Hoc Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
To evaluate the performance of the co-channel transmission based communication, we propose a new metric for area spectral efficiency (ASE) of interference limited ad-hoc network by assuming that the nodes are randomly ...
Handover authentication for mobile networks: Security and efficiency aspects
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
A handover authentication module in mobile networks enables mobile nodes to securely and seamlessly roam over multiple access points. However, designing an appropriate handover authentication protocol is a difficult task ...
