Effective detection of jamming in WiMAX based communication systems

WiMAX is a wireless technology based on IEEE 802.16 specifications and its main motive is to provide cable/DSL free high speed broadband access in the rural areas. Security and performance issues would become more important if one is dealing with communication as is in WiMAX. This paper is devoted to propose a simple and efficient technique to detect jamming in WiMAX based system. The proposed technique involves the metrics such as Signal to Interference plus Noise Ratio (SINR), Received Signal Strength (RSS), Packet Delivery Ratio (PDR) and Channel Sensing for detecting jamming in the WiMAX system. Finally, a mechanism for recovery from jamming is also illustrated with a tentative comparison in between proposed and existing techniques.
