In wireless sensor network nodes position estimation in space is known as localization. Node localization in wireless sensor network is important for many applications and to find the position with Received Signal Strength Indicator requires a number of anchor nodes. However the estimation of distance from signal strength decay in not very accurate especially in time varying environmental conditions and the estimation of exact direction required highly directive antenna but, may still affected by multipath fading. A Genetic Algorithm for wireless sensor network localization is proposed in this paper to solve the issue that the positioning accuracy is low with minimum anchor nodes. Hence in this paper we are presenting a Genetic algorithm for optimization approach which tries to find the optimal location by satisfying both the criteria with minimal error. The simulation results also shows effectively outperform both the techniques.
Wireless mesh networks (WMNs) have gained considerable interest in expanding IEEE 802.11 networks to large-scale enterprise and community scenarios, primarily because of its capability of providing wide-band network access to a significant number of users. However, the mesh nodes are typically limited in resources such as bandwidth, computation power and memory. Capacity limitation is one of the fundamental issues in wireless networks. Excess capacity(EC) is the unused capacity. Here in this paper EC Management techniques are used to improve network performance.
This paper presents the generation of optical carrier suppressed signal for RoF system. RoF refers to an analog transmission over fiber technology where light is modulated by radio frequency (RF) signal and transmitted over an optical fiber link to wireless access. Both optical carrier suppression and signal modulation are made by using a Dual-Drive Mach-Zehnder modulator (DD-MZM). Suppressed carrier modulation is achieved by biasing at the null point of DD-MZM. Optical carrier suppression improves the performance of RoF system such as link gain and noise figure (NF).In this research, a single RF at 2100 MHz having data rate of a 1 Gbps modulates the 1550.12 nm optical carrier in the DD-MZM. In this paper, the carrier suppression and performances of RoF system are investigated by theory and simulation. The various values of optical carrier suppression ratio can be obtained by adjusting the extinction ratio of the DD-MZM.
Planar inverted-F antennas are miniature designs that offer considerable versatility for both mobile and other wireless applications. The design is particularly suited for mobile devices.
1888 PressRelease - While the City of Chicago was selected for Cisco's Host City for the 2014 Internet of Things World Forum, Everywhere Wireless was engaged by Cisco to provide Internet connectivity to power the Forum and Wi-Fi infrastructure, which will be installed at the intersection of Michigan Avenue and Wacker Drive, where the Smart City Walking Tour will be held.
The most straightforward and most economical opportunities to consider when beginning out are laser-based systems that usually use a magnetic attached laser receiver on the machine with a grade lasers for advancement and grade. The laser receiver proposes both visible and audible indication for above, below and on grade location. These verified systems have been accessible for a many years and let machine operators of backhoes, skid steers, dozers and smaller excavators to distinguish precisely where grade and elevation is minus the use of a grade checker. Varying on the system components and machine type, these laser-based systems can be used for flat, slope and cross slope grade control. Furthermore some laser-based systems use an in-cab control box to deliver automatic control of the blade. Laser-based systems are normally very simple to set up, and need very little training. Moreover, some laser based 2D systems for mini excavators and backhoes use wireless sensors to measure
