Abstract:- In recent years, there has dramatic proliferation of research concerned with Radio Frequency Identification (RFID). The RFID technologies are getting considerable attentions not only academic research but also the applications of enterprise. One of most important issues of applications is the indoor position location. Many researchers have used varied technologies to perform the tracking of indoor position location. In this paper, we will purpose a new method using RFID tags to perform indoor position location tracking, too. This method uses Received Signal Strength (RSS) to collect signal strength from reference tags beforehand. Next, signal strength is used to set up Power Level areas of ranges by reference tags. And then, using signal strength from reference tags to match signal strength by track tags. Finally, when track tags is set up into indoor environments, it will find out the position of neighboring reference tags, and using arithmetic mean to calculate the location values. A preliminary experiment proves that our method provides a better precision than LANDMRC system. Key-Words:-RFID, indoor position location, RSS, Powel Level, location identification, LANDMRC 1

A new method of moments (MoM) code is discussed. The code supports standard functionality, e.g. fully automatic re-meshing and variable’s assignment, ground plane and symmetry planes. In addition, the code realizes several new features. These include significant acceleration of the filling-in of the impedance matrix for high accuracy calculations on structures with redundancies, as well as realization of the multiple domain basis functions with a support for various aggregating basis function’s profiles, including piecewise linear and piecewise sinusoidal. New profiles may be easily defined. The current realization of the code has been tested on several references and showed an excellent match to the reference results. 1.

Abstract:- Interference is one of the challenges that limit the performance of Wireless Mesh Networks (WMN). It became a major issue with new devises being equipped with more than one radio interface. This research emphasizes on impact of interference in multi-hop / multi-radio WMN’s throughput as a result of utilizing dual radios in WMN’s station. Various laboratory experiments in this research indicates that the IEEE802.11 non-interfering channels for the 2.4GHz band still exhibit some level of interference. Furthermore, we proposed an interference cancellation circuit that showed a noticeable throughput enhancement in our experiments. This validates the proposed solution for interference suppression and throughput enhancement..
