Energy saving by using floating input approach in a wireless sensor network

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 freights or container as the entities of a big transportation network. Results of implementation prove more than fifty percent of energy saving on the sensor nodes while operating. The most important advantage of proposed method is that it can be used together with the other techniques of energy saving.
