Security in WLAN, WPAN, WSN and WMAN through Wi-FiTM, BluetoothTM, ZigBeeTM and WiMAXTM

Abstract

Security constitutes a crucial problem for wireless networks whose diffusing of transmission is shared. WhereasWi-Fi/Bluetooth products flood the market on a worldwide scale and give access to Internet, the companies become increasingly demanding security guarantees. Security thus seems one of the major stakes for the operators. Additionally, securing the link does not secure the complete transmission and requires complex authentication procedures that establish a trust between entities that are not logically related.
