Abstract

Location systems based on WSN are built using diverse technologies. Factors such as the programming language to implement the location algorithm, the underlying operating system (available libraries, closed APIs,...) and type of hardware node interfaces, frequently drive us to a non-reusable design. Usually, the WSN technology cannot be easily replaceable by another one. We introduce a novel layered architecture that allows the abstraction of both WSN and location algorithm layers, communicating them by means of XML-RPC. As main advantages, both layers are now reusable, can be implemented with different programming languages, be distributed over different machines and it is possible a concurrent access to the WSN from different clients.
