Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared to waiting […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications
This paper proposes a novel interference-resistant receiver for wideband long-term evolution (LTE) system which employs orthogonal frequency division multiple access (OFDMA) for the downlink. In case the received spectrum is underutilized, compressed sensing (CS) enables us to operate at a sub-Nyquist sampling rate for lower device cost, higher data transmission rate and faster spectrum sensing […]
Read moreThe fastest growing of multimedia services over future wireless communication systems demands more network resources, efficient delivery of multimedia service with high user satisfaction, and power optimization of user equipments (UEs). The resources and power optimization are significant in future mobile computing systems because emerging multimedia services consume more resources and power. The 4G standard […]
Read moreIn this letter, a wideband semisolid skin-equivalent phantom with dielectric properties close to human skin in the V and W band is proposed. The constituents of the phantom are deionized water, agar, and gelatin powder. The phantom has been fabricated and validated by an open ended waveguide method. Since it comprises of low-cost constituents and […]

A stochastic geometry analysis of inter-user interference in IEEE 802.15.6 body sensor networks
Inter-user interference deteriorates reliable communication in body sensor networks (BSNs) when multiple BSNs are transmitting simultaneously in close proximity to each other. Stochastic geometry provides a natural way of modeling the placement of interferers, by averaging over all potential geometrical realizations for the interferers. This paper presents a stochastic geometry analysis of inter-user interference in IEEE 802.15.6 BSNs. The […]
Read moreThree 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 […]
