In this paper, we assessed feasibility of using Photoplethysmography (PPG) signal from flexible biosensor as an alternative solution to ECG for monitoring of cardiovascular and pulmonary performance. The potential advantage of this methodology is reduction in power consumption and improvement of complexity of body worn wireless multisensory platform for(More)
Reliable Vehicular Ad-Hoc Networks (VANETs) require secured uninterrupted uplink and downlink connectivity to guarantee secure ubiquitous vehicular communications. VANET mobility, multi-fading wireless, and radio channels could result in unsecured and disrupted vehicular communications, isolating some vehicle nodes and making them vulnerable to security(More)
—In this paper, a transmission of JPEG2000 images using an Unequal Power Allocation (UPA) scheme and Orthogonal Frequency Division Multiplexing (OFDM) technique over a block fading-frequency selective channel is presented. Using instantaneous and average channel state information, power is assigned to each bit in the JPEG2000 bitstream based on its(More)
