Abstract: Bluetooth (IEE 802.15.1), ZigBee (IEEE 802.15.4) and Wi-Fi (IEEE 802.11) are three emerging wireless technology in the area of short range wireless communication. Bluetooth is intended to support a list of application such as data, audio, graphics and even video. For example, device can include cordless keyboard, mouse, and hands free headset and standard phones. The primary purpose of ZigBee is to monitor and control networks wirelessly. Wi-Fi is amid at computer to computer connection wirelessly instead of traditional cable network. In this paper, it is being to represent a comparative study of these wireless protocols, evaluating their main characteristics and performance in terms of some metric such as co-existence, data rate, power consumption, network size, cost, distance coverage and security. For application engineers this paper will help him to select an appropriate protocol.
