UHF RFID portal, usually composed by two or three antennas which connect to one reader. However, RFID system designers often feel puzzle about the antenna deployment since they have no idea of how high or which angle the antenna should be or how many antennas should be deployed. An antenna deployment optimization and evaluation method was proposed in this paper, which can guide the designer to optimize...
One shortcoming of ant colony optimization is that it can not be applied on continuous optimization problems directly. In this paper we propose a new approach for solving continuous optimization problems using ant colony algorithm. While the method maintains the framework of the classical ant colony algorithm, it replaces the discrete frequency in the ant selecting probability by a continuous probability...
Wireless indoor positioning systems have become very popular and attractive in recent years. These systems have been successfully used in many fields such as asset tracking and inventory management, and location fingerprinting schemes are the most promising technique because of technical restrictions. However, how to optimize the location of access points to improve the positioning accuracy is still...
