Methods and systems for operating a sensor network comprising a plurality of nodes and at least one resource, where a resource can be a sensing device (e.g., a camera or microphone) or other peripheral devices (e.g., a storage or recording system). In at least one embodiment of the present invention, at least one node in a network determines at least one resource available to it and the type of the resource or its capabilities. Based on the type or capabilities of the resource, the node associates with one or more logical node names and acquires instructions for performing at least one function.

Methods and systems for operating a logical sensor network

A network router is tested for operation according to a given network protocol, by coupling the router under test (RUT) to a test host device and arranging the device to simulate operative test network topologies which include router nodes, network nodes, and edges between the nodes. The device exchanges information packets with the RUT for each of a number of successive test network topologies. Each successive topology is determined randomly by inserting or deleting an edge or a node to or from a prior test network topology in a probabilistic manner. Operation of the RUT under the given protocol is evaluated based on the exchanged information packets. A judgment, e.g., a fault or a no-fault condition, is rendered by the host device.
