Advances in Wi-Fi technology have made Wi-Fi the preferred access method for everything from social media to business-critical applications. This has raised expectations for high performance to new levels, and any negative impact needs to be resolved immediately. Retry rates are the most reliable indicator of performance issues, and quickly diagnosing high retry rates and isolating them to a ro...

The role of the ventromedial nuclei of the hypothalamus (VMN) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. Electrolytic lesions were induced stereotaxically (1.2 mA, 15 sec). Results revealed a significant decrease (p<O.05) in body weight (BW) and food intake (FI) in the order of lesioned <sham <control during the fIrst week. However, ...

Wireless networks are now proliferating due to the success of the IEEE 802.11b protocol, also known as “Wi-Fi” (Wireless Fidelity). A Wi-Fi network is characterized by a set of base stations (also called access points) placed throughout the environment and connected to the traditional wired LANs. This technology allows nomadic users a broadband access to the Internet if they are in the transmis...

The development of health tele monitoring through wireless body area networks (WBANs) is an evolving direction in personalized medicine and home-based mobile health care. In a health tele monitoring system, a WBAN consists of a number of lightweight miniature sensors. The sensors measure physiological parameters such as electrocardiography (ECG), electroencephalogram (EEG), body temperature, an...
