EVALUATION OF THE ENERGY CHARACTERISTICS OF MULTIPLE ACCESS IN WIRELESS NETWORKS
We consider the wireless sensor network of the Internet of things, combining smart things with Autonomous power supply, which exchange information messages with each other. The lifetime or performance of such a network depends on the energy capacity of the batteries of smart things. It is shown that the algorithm of multiple access intended for division of the General physical environment of interaction between many sources of loading renders essential influence on time of working capacity. The models reflecting the mutual influence of probabilistic-time and probabilistic-energy characteristics of information interaction of smart things in the ethereal environment and allowing to find a balance between the quality of service and energy costs are investigated. The dependences of the average time and probability of timely delivery of messages generated by smart things, and the information speed of the real-time terrestrial network on the power of the radio signal on the transmitting antenna are obtained.
