摘要：Wireless sensor network localization is an important area that attracted significant research interest. This interest is expected to grow further with the proliferation of wireless sensor network applications. As localization is becoming popular, many attacks on the localization process are also on a rise. These attacks confuse the localization process and cause location estimation errors. Range based methods like received signal strength indication (RSSI) is affected a lot by physical attacks. This paper proposes a solution based on multi frequency multi power antenna to provide robust and accurate localization technique . In addition this paper proposes a grid coloring algorithm to detect the signal hole map in the network which is refer to the attack prone regions in order to take a corrective actions . The simulation results showed improvement in the localization accuracy in the presence of barrier attacks through detecting , filtering and eliminating the effect of these attacks.
