Localization system is important when there is an uncertainty of the exact location of some
fixed or mobile devices. In this paper, the problem of localization system to estimate the position of
randomly deployed nodes of a wireless sensor network (WSN) is addressed, a propose algorithm named
Improved Accuracy Distribution localization for wireless sensor networks (IADLoc) is issued, it is used
to minimize the error rate of localization without any additional hardware cost and minimum energy
consumption and also is decentralized implementation. The IADLoc is a range free and range based
localization algorithm that uses both type of antenna (directional and omni-directional), it allows
sensors determine their location based on the region of intersection (ROI) when the beacon nodes send
the information to the sink node and the latter sends this information to the sensors relying on the
antenna.
