Wireless sensor networks are rapidly growing. Wireless sensor networks are composed of a large number of radio frequency equipped sensor devices that autonomously form networks through which sensor data is transported. These sensor devices are used in various real life applications. Recent advances in wireless communications and electronics have enabled the development of low-cost, low-power, small-size sensor nodes. These sensor nodes are deployed in a wide area and are used to monitor a given field of interest for changes in the environment. Location tracking in wireless sensor networks is an important application area. The focus of this paper is on location tracking using wireless communication. In this paper, we present a visitor tracking method based on wireless sensor networks.
