In this chapter we have presented a discrete-event coordination scheme for sensor networks composed of both mobile and stationary nodes. This architecture supports highlevel planning for multiple heterogeneous agents with multiple concurrent goals in dynamic environment. The proposed formulation of the DEC represents a complete dynamical description that allows efficient computer simulation of the WSN prior to implementing a given DE coordination scheme on the actual system. The similarity between simulation and experimental results shows the effectiveness of the DEC for simulation analysis. The obtained results also prove the striking potentialities of the matrix formulation of the DEC, namely: straightforward implementation of missions on the ground of intuitive linguistic descriptions; possibility to tackle adaptability and scalability issues at a centralized level using simple matrix operations; guaranteed performances, since the DEC is a mathematical framework which constraints the behaviour of the single agents in a predictable way. Future research will be devoted to the development of highlevel decision making algorithms for the dynamic updates of the matrices of the DEC, in order to automatically reformulate the missions on-line according to the current topology of the network and the current perception of the environment.
