The widespread popularity of Wireless Local Area Network (WLAN) is recognized as an effective approach to complementing cellular networks for the high data rate and cost effective connectivity delivered to mobile users. Efficient handover and offloading schemes for integrated WLAN and cellular networks, referred to as Heterogeneous Wireless Networks, have thus attracted lots of attentions from ...

Ultra Wide Band (UWB) technology is a developing wireless technology which promises high data rate short distance communication. In this paper, propose an advanced method for generating UWB signal for many UWB related applications. Important area of application is Wireless Local Area Network (WLAN). The basic idea of the work is to develop pulses of nanosecond range for the UWB transmission and...

In this paper an overview of the wireless local area network (LAN) area is provided. The two types of wireless LAN topologies used today, infrastructure and ad hoc, are presented. The requirements that a wireless LAN is expected to meet are discussed. These requirements impact on the implementation of both the Physical and MAC layer of a wireless LAN. The unique characteristics of wireless phys...

The study of the 802.11 standard has been very intense for more than a decade now. Several works have striven at understanding its performance, even in the simplest topology of a wireless local area network (WLAN) with a single access point (AP). The present survey is an effort to classify and present the enormous literature on the subject into several important casescenarios, and summarizes th...

<span>Wireless mesh network (WMN) is a new trend in wireless communication promising greater flexibility, reliability, and performance over traditional local area (WLAN). Test bed analysis emulation plays an essential role valuation of software defined node mobility the prominent feature next generation network. In this study, models employed for moving mobile stations are explored. Moreo...

Wireless Local Area Networks (WLANs) for public access need to provide privacy between users and also ensure correct charging where access is based on payment. However, by design, conventional LANs and WLANs provide direct, unmediated communications between networked devices at the link layer. The paper presents a method to allow networked client devices to communicate with a network comprising...

In this paper, a planar antenna for Long Term Evolution (LTE) bands and Wireless Local Area Network (WLAN) is proposed. The based on coupled-fed monopole with distributed inductor direct-fed monopole. These three components form two of operations namely low operating band from 0.59 to 0.635 GHz high 1.67 2.80 GHz. satisfy the WMTS 610, UMTS 1700, GSM 1800, LTE 1900, 2100, WLAN 2400, 2600 3600 a...

Wireless Local Area Network (WLAN) is susceptible to security provisioning in spite of the solutions such as the Wired Equivalent Protocol (WEP) or IEEE 802.1x. This paper proposes an integrated scheme for intrusion detection in WLAN systems. The proposed scheme operates with one or more Gathering Agents (GAs) and a Master Server (MS). Each GA is used to get security information by collecting t...

It is always the hotspot of society attention and academy study how to improve the efficiency of large-scale instruments and equipment (LSIE). Constructing a Data Collection System based on Wireless Local Area Network (WLAN) is an important method of lab performance management and then promoting the LSIE integration efficiency. Focus on the WLAN environment LSIE working state information collec...

A compact CPW-fed fractal circle monopole antenna with dual wideband is presented for simultaneously satisfying wireless local area network (WLAN) for 2.4/5.2/5.8 GHz application. The antenna consists of irregular shape circles based on the Descartes circle theorem. The simulated -10 dB bandwidth for return loss is from 2.04 to 3.35 GHz and 4.96 to 5.9 GHz, covering all the 2.4/5.2/5.8 GHz WLAN...
