The present article focuses on energy aspect in a wireless sensor network. It employs a novel technique based upon system identification to prolong life time of the corresponding sensor nodes which have been scattered inside a closed space container to measure the variables of the environment, temperature and relative humidity. Collected information can be utilized to make decision either about the...
For implementation of wireless sensor network in logistic applications and in general in automation process applications, two network structures are considered: autonomous and central. In this paper, these two structures are compared in terms of robustness and control quality. An experiment for controlling the humidity of an apple orchard is conducted. Autonomous and central wireless sensor network...
This paper studies a combinational algorithm of a limit-trend checking, plausibility test and model-based method to attain a secure fault diagnosis in a wireless sensor network. It has been implemented based on a new theoretical identification method. The sensor nodes of the network have been distributed inside an intelligent container to monitor environmental parameters (temperature and relative...
