Performance of a Simple Positioning Algorithm (SimPA) in Wireless Heterogeneous Mobile Mesh Networks

Localization information is now a valuable data for every type of services and networks. But determining the physical location of a node in a wireless mobile environment is a challenging task for nodes with no self-locating capability such as a GPS. Simple Positioning Algorithm (SimPA) is a realistic, light and simple solution to estimate a position for such heterogeneous wireless networks and is based on a connectivity approach. This paper addresses the performance of SimPA in a mobile context such as a wireless heterogeneous mobile mesh networks. The authors present an evaluation of SimPA's accuracy for several mobility models.
