“…And to increase the robustness of building networked systems, many research efforts are made on integrating multiple information networks in intelligent buildings [14], with the protocols such as TCP/IP [15] [16], BACnet/IP [17], UPnP [18], middleware and so on. The integrations indeed reduce the system redundancy and increase system robustness.…”

Adding wireless communication capabilities to networked systems can effectively improve its connectivity, which in turn improves the robustness of the system under emergency. When the resource is limited, only finite wireless communication capacities can be installed to the existing nodes. It is in general difficult to determine which nodes to install in order to achieve the required connectivity, leaving alone the further task to find the installation with efficiency requirement. We consider this important problem in this paper and make the following major contributions. First, we develop an algorithm to configure the network to achieve biconnectivity through installing the minimal number of wireless communication devices. Second, when there are multiple such installations, we further develop an algorithm to pick the installation that maximizes the efficiency of the network. Both algorithms are polynomial w.r.t. the network size. The performances of both algorithms are demonstrated through numerical examples. We hope this work brings insight to topology optimization in more general situations.Index Terms-topology optimization; biconnectivity; connectivity 2012 American Control Conference Fairmont Queen Elizabeth,

“…A device without flash memory can use an autoconfiguration protocol to download its configuration from network management. But network (2) Channel measurement: all participating nodes cooperate to perform measurements of the wireless channel, such as RSSI measurement. The measurements are transmitted to the management workstation to assemble the measured connectivity graph.…”

Address Assignment in Indoor Wireless Networks Using Deterministic Channel Simulation

A crucial step during commissioning of wireless sensor and automation networks is assigning high-level node addresses (e.g., floor/room/fixture) to nodes mounted at their respective location. This address assignment typically requires visiting every single node prior to, during, or after mounting. For large-scale networks it also presents a considerable logistical effort. This paper describes a new approach to automatically assign high-level addresses without visiting every node. First, the wireless channel is simulated using a deterministic channel simulation in order to obtain node-to-node estimates of path loss. Next, the channel is measured by a precommissioning test procedure on the live network. In a third step, results from measurements and simulation are condensed into graphs and matched against each other. The resulting problem, identified as weighted graph matching, is solved heuristically. Viability of the approach and its performance is demonstrated by means of a publicly available test data set, which the algorithm is able to solve flawlessly. Further points of interest are the conditions that lead to high quality address assignments.
