Performance Improvement for Wireless Sensor Networks

In this paper, we prove that our proposed localization algorithm named Improved Accuracy Distribution localization for wireless sensor networks (IADLoc) [1] is the best when it is compared with the other localization algorithms by introducing many cases of studies. The IADLoc is used to minimize the error rate of localization without any additional cost and minimum energy consumption and also decentralized implementation. The IADLoc is a range free and also range based localization algorithm that uses both type of antenna (directional and omnidirectional) it allows sensors to 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 by relying on the antenna. It performance was compared with previous algorithms HiRLoc, PTA and RAL in terms of the number of sensors, average localization error and execution time
