Description: Rendezvous layer protocols for Bluetooth-enabled smart devices-
Communication platforms for ubiquitous computing need to
be flexible, self-organizing, highly scalable and energy efficient, because in
the envisioned scenarios a large number of autonomous entities communicate
in potentially unpredictable ways. Short-range wireless technologies
form the basis of such communication platforms. In this paper we investigate
device discovery in Bluetooth, a candidate wireless technology for
ubiquitous computing. Detecting new devices accounts for a significant
portion of the total energy consumption in Bluetooth. It is argued that
the standard Bluetooth rendezvous protocols for device detection are not
well suited for ubiquitous computing scenarios, because they do not scale
to a large number of devices, take too long to complete, and consume too
much energy. Based on theoretical considerations, practical experiments
and simulation results, recommendations for choosing inquiry parameters
are given that optimize discovery performance. We prop

Description: Abstract: The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for ptimal number of cluster heads. Base on the analysis of LEACH energy dissipation model,novel lation method is derived from the total energy dissipation of a round. Simulation shows the
relationship of the optimal number of cluster heads, the number of frames in steady state phase and the distance between cluster heads and base station (BS).And it provides a theoretical basis for calculation of optimal number of cluster heads which can reduce
the energy consumption among nodes and achieves
an improvement on the network lifetime.

Description: A wireless 3G modem is a type of modem which connects to a cellular network instead of to the land line telephone system. It allows you to get broadband internet access anywhere you can get a cell-phone signal. Many cellular phones these days have 3G modems built into them.
There have been a lot of great articles that guide you how to write an internet dialer for regular modem (and most of them work for 3G modems too) but some information is missing, for example, signal strength, connection mode (GSM, GPRS, EDEG, HSDPA, etc.) and other information which is wireless modem related.
