For successful deployment of a wireless sensor network, reliable communication between the networks’ nodes is crucial. When communication and other wireless sensor networks constraints are taken into account, networks can be analyzed efficiently. The diagnosis of the network's operation can be done using the information gathered by the sensor nodes in the network. This paper discusses wireless sensor network diagnostics, describes so-called neighbourtables used to collect diagnostic data of the wireless CiNet network and the construction of them using the synchronization and management messages. The neighbourtables are embedded to the CiNet network cross-layer architecture and this solution results to relatively small energy overhead consumption caused by them. The information stored in neighbourtables can be used to monitor network behavior and to improve networks' packet routing and fault recognizing for the nodes, in both, nodes' and centralized applications' point of view.

Wireless sensor networks can be used to perform structural monitoring. Strain gauges, which can be glued on or integrated to the observed material, are the most common nondestructive sensing elements for measuring surface strain. Wireless strain gauge measurement system makes strain measurements more flexible while opening new targets of application in addition to those that traditional wired strain measuring systems can offer. We have implemented a long term strain measurement in a PVC-covered hall using wireless sensor network. In this paper we evaluate the functionality and suitability of the developed wireless system for this kind of monitoring. The paper discusses the experiences gained in the development and utilization of a wireless strain gauge measurement system. The calibration of measurement system as well as energy consumption issues are also brought under observation along with the reliability of communication aspects in the described measurement case.

Wireless sensor networks can be extended to include numerous different sensing devices. Strain gauges are the most common nondestructive sensing elements for measuring surface strain. This paper discusses the design, for the wireless CiNet network, of a strain gauge measurement system, which would make strain measurements more flexible while opening new targets of application in addition to those that traditional wired strain measuring systems can offer. The calibration and validation of the wireless strain measurements as well as energy consumption issues are also brought under observation.

Reliable communication is crucial for successful deployment of a wireless sensor network. Many environmental factors can affect the performance of radio links, and the deployment of a network without real-time information about link qualities can be a demanding task. This paper describes the CiNetView application that is intended to support the deployment and monitoring of wireless sensor network. CiNetView is based on diagnostic information collected by sensor nodes, and it allows the user to see a graphical presentation of the network topology and to monitor the network diagnostic information in real time.
