The relevance of the work is due to the emergence of a large number of new specialized exchange protocols for wireless sensor networks focused on event registration. In the domestic literature, this class of wireless networks is practically not considered. The goal of the work is to conduct an extended protocol analysis for wireless sensor networks oriented to event registration.
We consider the basic data transfer protocol for this class of networks – Low Energy Adaptive Clustering Hierarchy Protocol. Its advantages and disadvantages in terms of power consumption and reliability of received data are demonstrated. It is shown that the protocol does not always provide the choice of a node as the top of a cluster, which has an energy supply source sufficient for data
transmission. The functional capabilities of each protocol are briefly analyzed, the possibilities of registering the
place of occurrence of an event, recording several events occurring simultaneously, etc. are highlighted. The basic principles of the organization of each protocol are considered. Particular attention is paid to the power consumption of the network when using a particular protocol and methods to ensure the reliability of data received by the control unit. The mechanisms of explicit and implicit acknowledgment of data reception by the control unit and neighboring network nodes are considered. For real-time protocols, the estimated delay between the registration of an event by the sensor and the receipt of information about it by the control unit was evaluated. Analyzed methods of preventing overload in the network in the presence of a large number of active sensors. According to the results of the comparative analysis, a summary table was created, demonstrating the features of each protocol and its functionality.
