Light Weight Location Verification Algorithm in Wireless Sensors for Checking the Reliability of Data

Abstract

Wireless sensors can be deployed in any environment, even if that is hazardous and they send back the data gathered to the verification center which is placed at some safe location. Since the data collected by these are very vital so any compromisation may lead to undesirable results. Sensors can be easily compromised by changing its actual position to some false position so there is need for some algorithm to verify the position and ensure that the data is unblemished. Since in previous scheme, heavy and expensive equipments were used along with the deployment knowledge required, it becomes inefficient for all cost range. Therefore, we have proposed a verification system which utilizes the concept of on-spot and in-region location verification. In on-spot verification, we calculate the distance of the wireless sensor from its actual deployed position. In-region verification depends upon neighbouring sensors. Along with that, once a sensors gets out of its tolerable region, even for once, its data gets discarded. Putting the sensors back to its original position after the discarding of the data won’t make it trusted and the sensor will still be considered compromised. This additional feature ensures that the data received in the verification center is from a trusted device and is true.
