HiRLoc: High-resolution Robust Localization for Wireless Sensor Networks
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 2
Abstract
In this paper the tiny nodes are deployed in target areas according to the deployment nature of target but nodes are easily targeted by attacker with physical attack of node capture. So, secure,communications in some wireless sensor networks are critical because these networks are highly vulnerable to internal and external attacks. In our paper, we present an enhanced High-Resolution Robust Localization for security of wireless sensor networks. This combination of scheme provides the good performances and efficiency in terms of network connectivity. We propose a range-independent localization algorithm called HiRLoc that allows sensors to passively determine their location with high resolution, without increasing the number of reference points, or the complexity of the hardware of each reference point. In HiRLoc, sensors determine their location based on the intersection of the areas covered by the beacons transmitted by multiple reference points. we show that HiRLoc is robust against known attacks on WSN.. Finally, our performance evaluation shows that HiRLoc leads to a significant improvement in localization accuracy compared to state-of-the-art range independent localization schemes, while requiring fewer reference points
