The communication delay, which has great impact on vehicle-to-infrastructure (V2I) networks, faces a large challenge on account of complex network topology. In this paper, a novel architecture that integrates LTE networks with IEEE 802.11 based Vehicle Ad Hoc Networks (VANETs) is proposed, due to their high data transmission rates and wide coverage area, respectively. The proposed scheme […]

Second-Order Cyclostationarity-Based Detection of LTE SC-FDMA Signals for Cognitive Radio Systems
In this paper, we investigate the detection of long-term evolution (LTE) single carrier-frequency division multiple access (SC-FDMA) signals, with application to cognitive radio systems. We explore the second-order cyclostationarity of the LTE SC-FDMA signals and apply results obtained for the cyclic autocorrelation function to signal detection. The proposed detection algorithm provides a very good performance under various […]
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 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 moreReducing the operating energy of a distributed feedback (DFB) laser is a critical issue if we are to use the device as a directly modulated light source employing wavelength division multiplexing technologies in short-distance datacom networks. A membrane buried heterostructure (BH) DFB laser on a SiO2layer is one candidate for reducing the operating energy because […]

Design of rectangular microstrip patch antenna based on Artificial Neural Network algorithm
The Design of Rectangular Microstrip Patch Antenna using Artificial Neural Network (ANN) has been presented. This paper used Feed Forward Back Propagation Algorithm (FFBPN), Resilient Back-propagation (RPROP), Levenberg-Marquardt (LM) and Radial Basis functions (RBF) of ANN to obtain the resonant frequency of rectangular microstrip patch antenna. The model of ANN algorithm was developed and implemented […]
Read moreThis paper investigated the feasibility of using the radio signal strength of sensors placed around the human body in the human movement identification. This proposed method can identify the human movement in WBAN using only the radio signal strength, thus any additional tools are not necessary. OpenNICTA provides the BAN measurement channel in three kinds […]
Read moreVehicular Ad-Hoc Network (VANET) is an exponential growing technology in today’s modern computing era. Vehicle are peers of peer to peer network. All vehicles are having mobility. In this paper we have presented an evaluation of routing protocols AODV, DSDV and DSR on basis of test performance metrics like generated packets, received packets, dropped packets, […]

Performance Evaluation of MAC Protocol and Routing in Multi-Rate Wireless Ad-Hoc Networks
The medium access control (MAC) and routing are fundamental parts in the design of wireless ad-hoc networks. A joint routing protocol and medium access control based on CSMA-CDMA with multi-rate transmission capability for ad-hoc networks are proposed in this paper. Simulations show the effectiveness and validation of the proposed protocol. Furthermore, these simulations present a […]

The Application of SOM Network to Particle Tracking Velocimetry in a Wind-Blown Sand Flow
Wind-blown sand flow is the basic phenomena that have profound influences on the environment, and the experimental study on the velocity distribution of the sand particles is very important for the understanding of this phenomena. Among the various experimental techniques, particle tracking velocimetry (PTV for short) is one that attracts more and more attentions. In […]
