The expansion of the Internet and the reduction in the cost and size of integrated circuits has given birth to a new breed of devices that contain a monitoring and controlling application. Terms such as Home Networks, SmartSpaces and SmartHomes are used to refer to networks consisting of such devices. These networks may consist of devices that confirm to a variety of device communication protocols such as IEEE 1394, X10, HAVi etc. Also, it is possible that some of these devices are mobile. The VHN is an example of such a network [1]. The management of such a heterogeneous mix of devices is essential for the proper functioning of the network and also for taking timely corrective actions.
