Three types of flexible textile antennas for 2.45 GHz body area network (BAN) are compared in this letter. Two types of conducting materials are used to form radiation patch and ground plane, they are called copper foil tape (CFT, 0.05 mm thickness) and Shieldex (SH, 0.13 mm thickness, 0.009 Ohm surface resistivity). The substrate is […]

Smart community health awareness model
In this paper we present a novel cloud supported model for efficient community health awareness in presence of a large scale WBANs data generation. The objective is to process this big data in order to detect the abnormal data using MapReduce infrastructure and user defined functions with minimum processing delay. The goal is to have […]
Read moreA weighted polling access scheme for Wireless Body Sensor Network (WBAN) is proposed in this paper. In this scheme the sensor nodes are divided into groups and each group has a weight. Each sensor node of each group can transmit packets up to the value of weight, thus limiting the number of packet transmission per […]
Read moreBrain-machine interface (BMI) technology has tremendous potential to revolutionize healthcare by greatly improving the quality of life of millions of people suffering from a wide variety of neurological conditions. Radio-frequency identification (RFID)-inspired backscattering is a promising approach forwireless powering of miniature neural sensors required in BMI interfaces. We analyze the functionality of millimeter-size loop antennas in […]
Read moreIncreasingly, incidental sensing capabilities are being leveraged for wide-area situational awareness of complex network processes. For instance, sensors embedded on miners’ body suits are envisioned for sensing for chemical hazards, blog data is being used to track disease spread, and autonomous vehicle platforms can incidentally measure environmental conditions while engaging in mission tasks. This paper explores how sparse incidental measurements […]
Read moreIn this letter, we propose the reactive relay selection scheme based on cumulative distribution function (CDF) of SNRs for two-way relay networks over Nakagami-m fading channels. We analyze average relay fairness by deriving the exact integral and asymptotic expressions for relay selection probability. Also, we obtain diversity order by deriving outage probability. Numerical results show […]
Read moreWith the advent of smart portable devices and location-based applications, user’s mobility pattern is found to be highly dependent on varying locations. In this paper, we analyze asymptotic throughput-delay performance of mobile ad hoc networks (MANETs) under a location popularity based scenario, where users are more likely to visit popular locations. This work provides a […]
Read moreThe emerging trend towards utilizing chip multicore processors (CMPs) that support dynamic voltage and frequency scaling (DVFS) is driven by user requirements for high performance and low power. To overcome limitations of the conventional chip-wide DVFS and achieve the maximum possible energy saving, per-core DVFS is being enabled in the recent CMP offerings. While power […]

New Approach to the Stability of Chemical Reaction Networks: Piecewise Linear in Rates Lyapunov Functions
Piecewise-Linear in Rates (PWLR) Lyapunov functions are introduced for a class of Chemical Reaction Networks (CRNs). In addition to their simple structure, these functions are robust with respect to arbitrary monotone reaction rates, of which Mass-Action is a special case. The existence of such functions ensures the convergence of trajectories towards equilibria, and can be […]
Read moreNetwork selection plays an important role in load balancing and radio resources management. In this paper, we use the evolutionary game theory to address the network selection problem in the constrained heterogeneous networks. An indication function is introduced into the payoff function to represent the punishment term. The population dynamics can be obtained by the […]
