Wireless local area networking standard (Wi-Fi) and the WPAN standard (Bluetooth and Zigbee) products utilize the same unlicensed 2.4 GHz ISM band. Co-existence between such wireless technologies within the same frequency spectrum is crucial to ensure that each wireless technology maintains and provide its desired performance requirements. In this paper, we(More)
Nowadays, Radio Frequency Identification (RFID) is a popular automatic wireless identification technology, and provides promising benefits in a number of application areas such as supply chain management. Though RFID technology has attracted a significant attention due to the convergence of lower cost and increased hardware capabilities, there still exist(More)
The use of 802.11 long-distance links is a cost-effective means of providing wireless connectivity to rural areas. Although deployments in such settings are increasing, there are few empirical results reported on the performance of 802.11 over long distances. An empirical evaluation of 802.11 performance over long distances is a non-trivial task since it(More)
In healthcare the importance of obtaining the right information, at the right time, irrespective of time and location dependency is very critical. Healthcare personnel need to access real-time medical data such as patient clinical histories, laboratory results, treatments, chronic diseases, medication, and insurance information. Therefore, healthcare is the(More)
This paper investigates the impact of security on the performance of WLAN. More specifically, it analyzes the impact of applying encryption used by the well-known security protocol wired equivalent privacy (WEP) on the data rate over an ad hoc WLAN, IEEE 802.11g. This paper also addresses the different issues related to the security protocols currently used(More)

The steep growth in demand and deployment of WLAN/WPAN for short range connections has been driven by the need to create networks, where one can be connected anywhere at any time making many services and application a click away. These short range access networks currently exist almost everywhere, at home, at the work place, hotels, hospitals, etc. wireless(More)
When GSM was introduced in the early 90's, it was considered an over specified system. Nowadays, it is obvious that the whole range of services is widely in use. In addition, performance is degrading due to the rapidly increasing number of mobile subscribers, numbering over 2.9 billion subscribers around the world. The performance of cellular networks is(More)
