Performance Analysis and Comparison of Wireless Protocols Standards in WPAN-Bluetooth and WLAN-Wi-Fi

Communication is going wireless with the upsurge of smart mobile devices such as laptops, cellular phones, PDA, tablets etc. In order escape traps of wires and to stream data wirelessly among these devices, a number of protocols have been formulated such WPAN-Bluetooth and WLAN-Wi-Fi. Using these technologies users can exchange almost all sorts of files at high speeds. Bluetooth is oriented to connecting close devices serving as a substitute for cables while Wi-Fi is oriented towards computer to computer connections, as an extension of or substitution for cabled LANs. This paper presents the performance analysis and comparison of all of these popular wireless communication standards, comparing their main features and behaviors in terms of various metrics, including capacity, security, QoS, and power consumption.
