OBJECTIVES The purpose of this study was to develop a prototype wireless local area network (LAN)-based tracking system and evaluate its efficacy. METHODS A wireless LAN-based tracking system was developed with a personal digital assistant (PDA) having a simple text messaging function and a prototype stand-alone tracking device. Evaluation of the effectiveness of the tracking system was perfo...

In recent years, wireless LAN systems are widely used in campuses, offices, homes and so on. It is important to discuss the security aspect of wireless LAN networks in order to protect data confidentiality and integrity. The IEEE Standards Association formulated some security protocols, for example, Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access Temporal Key Integrity Protocol (WPA-T...

In this study, the capabilities of an IEEE 802.11 wireless LAN are measured. For the test phases, three wireless laptop computers, a wireless and wired desktop computers and an access point (AP) are used. In addition to these computers, products of Lucent Technologies have been used as the wireless communication adapters. Our metric that is the criteria used to evaluate the performance of our W...

Cheap and available wireless devices are commonly used at our home and in institutions. Wireless local area networks (WLAN), new type of networks set us free from problems of changing wall socket location. That kind of LANs makes access to the Internet more comfortable. We do not have to drill holes in walls and put cables to connect another workstation to the existing network. To avoid such pr...

Service differentiation in wireless LANs is a growing demand, due to their increasing use for applications with different requirements and the scarcity of wireless channel resources, and is becoming particularly important with the emergence of wireless LAN hotspots. The contribution of this paper is twofold: First, we investigate how various parameters of the IEEE 802.11 MAC protocol affect ser...

IEEE802.11s draft proposes a new medium access control function-mesh deterministic access (MDA), which is mainly used for single-channel wireless mesh local area network (LAN). In single-channel environment, collisions between control packets and data packets may occur very often. To completely avoid the collision between control packets and data packets, the mesh delivery traffic indication me...

The aim of this work is to develop a wireless local area network (LAN) between different types of users (Radiation Oncologists, Radiological Physicists, Radiation Technologists, etc) for efficient patient data management and to made easy the availability of information (chair side) to improve the quality of patient care in Radiation Oncology department. We have used mobile workstations (Laptops...

Campus and enterprise wireless networks are increasingly characterized by ubiquitous coverage and high traffic demands. An efficient channel assignment of access points (APs) in these networks has the potential to greatly improve wireless LAN performance. Therefore, previous studies have investigated methods for determining effective channel assignments. Existing approaches, however, do not ada...
