Localization of Senor Nodes Using Weighted Least Squares Algorithm: Comprehensive Literature Review and Future Research Directions

In sensor nodes, localization is very important characteristic in wireless sensor networks. By using localisation technique, it can find out the position of any sensor node in the network. Technically, unlicensed users in this network share the spectrum of primary users using a spectrum sensing process while do not cause significant interference to the primary users. Unfortunately, the spectrum sensing process is hampered by security problem...
