Self-organization issues of wireless sensor networks

The topic of sensor networks is a high issue, it is a popular and up-to-date research field because of its manifold application possibilities. Ranging from the military tactical intelligence through border defence to disaster management, from intelligent homes to industrial process control there is a vast variety of usages, the common features of which is the minimisation of human resources and the realization of the widest possible scale of automation. An important component of sensor networks is the hardware that is the sensors themselves, however, the algorithms that are responsible for building relationships between the nodes of these networks, enable the transmission of data from one node to another and ensure fast and error tolerant operation also possess at least as high importance as sensors. These tasks must be realized at the least cost possible, in the most effective way that is in the most optimal way while taking the circumstances into account. This paper aims to classify the algorithms applied for these sensors and to compile a criteria system for this classification.
