Kulia Y. Methods for increasing the lifetime of the autonomous wireless sensor network

The object of study - functioning processes autonomous wireless sensor networks. The purpose of the thesis - the increase in the lifetime of an autonomous wireless sensor networks due to the choice of the optimal mode its work. Methods of investigation - analytic and simulation of processes affecting the life expectancy of an autonomous wireless sensor network. Theoretical and practical results - mathematical models and methods that can increase the life expectancy of an autonomous wireless sensor networks by optimizing management methods and regimes activity of the network node. Newness - were further developed models for estimating power WSN nodes. A new method of management of the energy balance of nodes WSN technology-based ZigBee. Further developed energy-saving techniques for solving routing, the novelty of which is the justification for a rational choice of the metric of routing protocols, given the elimination of the imbalance of power consumption. The degree of implementation - all these results can be used in the design of new and improvement of existing wireless networks personal wireless access standard IEEE 802.15 technology with "ZigBee" in the monitoring of various processes, systems of control and accounting of movement of goods and transport.
