The experimental approbation of the virtual coordinator implementation for increasing the life expectancy in wireless sensor network

Sensors and sensor networks have an important impact in meeting environmental challenges. Sensor applications in multiple fields such as smart power grids, smart buildings and smart industrial process control significantly contribute to more efficient use of resources and thus a reduction of greenhouse gas emissions and other sources of pollution. Nowadays, the most topical researches pertaining to wireless sensor networks are grounded on the new optimization of structure of network transmission protocol, the routing optimization in transmission network, optimization of network structure, as a result of which the life circle of wireless network sensors is possible to increase. This article describes the experimental approbation of the mobility of the coordinator node in a wireless sensor network which provides the wireless sensor network node grouping, the transmission protocol optimization and the adjustment to the current environment, resulting in a reduction of the power consumption in the network nodes and define the basic rules that affect the overall life expectancy of a wireless sensor network.
