Uniformity of magnetic field distribution over a wireless charging surface can be improved by having high-permeability ferrite material. In this paper, 0.5mm-thick ferrite material is appropriately shaped and disposed above a power transmitting unit (PTU) resonator.... by NS2 Simulator Project Team | Oct 14, 2015 | Wireless Simulation in NS2
For wireless networks which aim at high speed communication and computation, we propose a parallel analog function computation scheme via wireless multiple-access multiple-input-multiple-output channels. We consider that each sensor node only has imperfect channel... by NS2 Simulator Project Team | Oct 14, 2015 | Wireless Simulation in NS2
Variations in the RF chain of radio transmitters caused by imperfections of manufacturing processes can be used as a signature to uniquely associate wireless devices with a given transmission. In our previous work [1], [2] we proposed a modelbased approach that allows... by NS2 Simulator Project Team | Oct 14, 2015 | Wireless Simulation in NS2
The fifth generation (5G) wireless networks are expected to achieve 1000 times higher capacity compared to the fourth generation (4G) wireless networks. Thus, improving the spectrum efficiency (SE) is a crucial problem, which must be considered. Cognitive radio (CR)... by NS2 Simulator Project Team | Oct 14, 2015 | Wireless Simulation in NS2
Mobile applications are becoming increasingly computation-intensive, while the computing capability of portable mobile devices is limited. A powerful way to reduce the completion time of an application in a mobile device is to offload its tasks to nearby cloudlets,... by NS2 Simulator Project Team | Oct 14, 2015 | Wireless Simulation in NS2
We study the performance of centralized least meansquares (CLMS) algorithms in wireless sensor networks where nodes transmit their data over fading channels to a central processing unit (e.g., fusion center or cluster head), for parameter estimation. Wireless channel...
