Abstract

Wireless sensor networks (WSN), sometimes called wireless sensor and actuator networks (WSAN), are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure etc and to cooperatively pass their data through the network to other locations. The more modern networks are bi-directional, also enabling control of sensor activity. The design of a wireless sensor network requires many important factors that need to be taken into account. Some of them, are the environment in which the network will be placed, hardware constraints, fault tolerance, and production costs. One of the most important factors, is the management of the sensor node energy resources, which classify these networks. Wireless charging technology is a very promising technology. Modern developments in this area, as well as advances in battery materials that can be used, pave the way for new opportunities in how to manage energy in network sensors. This diploma thesis aims at design and implementation of a Load Energy Algorithm in a WSN, which will take into account all of the above. In the first part, we present the WSNs as well as the parts of them, the conditions that effect their function and the applications that they can be used for. Subsequently, we analyze the problem of the loss of energy, that is very important in WSNs and we present researches of the past. At the same time, we are referring to routing and other protocols about WSNs, because of their important role. In the final part, we are trying to implement an algorithm for the charging of the nodes in WSNs. In our effort, we combine two algorithms of charging from two older papers. The first one is about charging the nodes by the chargers while the second one is about the charging of the chargers by bigger chargers. The implementation is taking place in Matlab and after the presentation of the results in graphs, conclusions and proposals are made to help the continuation of the research about charging in WSNs.
