A major part of this project is deriving and implementing new methods for aggregating data. In many ways this is a new type of anycast problem, the dual problem of multicasting. In phase 2 of the project we will implement multi-resolution methods that solve this problem using mobile code.Refer to Multi-Sensor Fusion: Fundamentals and Applications with Software by R. R.
