A 3D-Based Positioning Model and Algorithm in Ad Hoc Networks

In ad hoc network, localization of node is very important and valuable it is also an important technology in the Internet of things. We present an improved localization model 3D-positioning model in ad hoc network (3D-PMAHN) based on Simic´s 2D-localization model in ad hoc networks. In 3D-PMAHN, space grid is presented. When one tag in ad hoc networks is detected by certain readers whose positions are known before, the tag´s position can be known through calculation. Simulation shows that the localization speed and precision are relatively fast and high.
