Abstract. Results of experimental study of the influence of periodic change of the interference intensity on the channel efficiency and network protocols are presented in the paper. Routing protocols are considered as network layer protocols. The protocol of control connection of the communication network with random multiple access is considered as protocol link layer. The intensity of the interference pulse type is consistent with the temporal parameters of routing protocol. The results show that the intensity of the interference greatly affects routing in network in which there are radio segments. Interference affecting leads to changing of routes in the network. This effect arises from the fact that the disturbance impairs the transfer packets transmitted in the radio segment, which leads to the breakdown of compounds in them. Periodic disturbance, the duration and period of which is coordinated with the duration and period of the send of the routing packets is the most complex for network. Experimental results confirm the effects of reducing the effectiveness of the protocols in random multiple access and routing protocols that have been theoretically justified earlier. These results can be used to develop new types of interference, and to explain new ways of anti-jamming communication networks.
