The design of a wireless local area network (WLAN) has two major issues: determining the best placement of base stations (BS) and assigning the frequency channels for those stations. The correct BS placement minimizes installation costs. The adequate channel assignment reduces signal interference and improve network throughput. This paper reports a real experience where we applied the concepts ...

Wireless indoor positioning has been a popular research topic for years because it provides the basis for a broad domain of location-based applications. Especially the usage of WLAN (Wireless Local Area Network) technology is widespread to build an indoor positioning system due to the reuse of existing and almost ubiquitous WLAN infrastructure worldwide lowering the costs. However, these WLAN s...

The integration of wireless local area networks (WLANs) and the high speed wide area network (WAN) using ‘always on’ broadband access that could provide an efficient and cost effective inter-WLAN mobility management requires the current WLAN internetworking protocol enhanced. The Inter Access Point Protocol (IAPP) defines methods for access point coordination over a distribution system to suppo...

IEEE 802.11 based Wireless Local Area Network (WLAN) system has been rapidly developed and deployed. With limitations of the standard and rapidly growing wireless application demand, the air interface acts as bottleneck even in high-speed WLAN systems such as 802.11a and 802.11g. To improve overall performance of 802.11 WLAN under large deployment and heavy application demand environment, a nov...

A network whose interconnections between nodes are implemented without using wires is referred to as wireless network and is usually related to a telecommunication network. As related to wired local area network, wireless channels are error-prone. Performance study and optimization of Wireless Local Area Network (WLAN) becomes more essential as its gaining popularity. For performance modelling ...

The role of Intrusion Detection System (IDS) has been inevitable in the area of Information and Network security – especially for building a good network defense infrastructure. Due to the wide popularity of Wireless Networks tremendous applications are emerging and Wireless Local Area Network (WLAN) has gained attention by both research and industry communities. The wide spread deployment of W...

Traditional network control system offers many advantages but requires cables to inter-connect devices, which leads to high installation and maintenance costs due to low scalability and high failure rate of connectors. As a result, wireless technologies have gained an enormous success in the consumer goods industry in the last few years. Wireless Networked Measurement Control System (WNMCS) is ...

Abstract—Wireless communication systems either ad hoc or infrastructure mode the key challenges that must be overcome to realize the practical benefits of Quality of Service (QoS). Generally the QoS is the ability for network element to provide some level of assurance for consistent network data delivery. The ability of Wireless Local Area Network (WLAN) to support real-time services is possibl...

In this paper, a dielectric resonator antenna (DRA) is presented for wireless local area network (WLAN) applications. Here three rectangular dielectric resonators are used as stepped manner. The DRA is excited by microstrip line which is an effective feed mechanism to obtain better radiation. In this design, rectangular shape was used as the dielectric resonator as it offers more option to cont...

The common trend in the new century has been for wireless computer networks to replace wired ones, due to increased mobility and greater convenience. Since the wireless network is simply broadcasting a signal, which anyone can connect to this Wireless Local Area Network (WLAN) and receive the signal with the proper equipment. Thus, these types of networks are fundamentally less secure than the ...
