Localization algorithms research in wireless sensor network based on Multilateration and Trilateration techniques

Recently there has been much focus on Wireless sensor networks (WSN). However Location information is one of the most important information in WSN. Many location estimation algorithms for WSNs have been used to determine the sensor nodes position. In this paper, two different localization algorithms using Trilateration and Multilateration mathematical techniques have studied and compared according to the number of anchor nodes. Some conclusions that are extracted verified that increasing the Number of anchor nodes could enhance the accuracy of the mean location error of location algorithm based on Multilateration technique.
