Abstract: Secure localization of unknown nodes during a Wireless Sensor Network (WSN) is a vital analysis subject. Wireless Sensor Networks (WSNs) are networks of distributed autonomous devices which will sense or monitor Physical or environmental conditions hand and glove. WSNs face several challenges, primarily caused by communication failures, with advancements in hardware style, communication protocols, resource potency, and different aspects. Recently, there has been a lot of target mobile device networks, and that we have even seen the event of small-profile sensing devices that are ready to management their own movement. though it's been shown that quality alleviates many problems with reference to device network coverage and property, several challenges stay. Among these, the necessity for position estimation is probably the foremost vital. a survey on localization strategies for mobile wireless device networks. they supply taxonomies for mobile wireless sensors and localization, as well as common architectures, measuring techniques, and localization algorithms. They conclude with an outline of real-world mobile device applications that need position estimation. Describe a 3 stage optimization technique is planned to reduce the calculable error and finding the situation of a node during a network.

Keywords: Wireless Sensor Network, security, localization,   mobile sensors, anchor nodes, Localization error, received signal strength.
