The basis of the information efficiency increasing of networks and means of Internet of Things is the implementation by processor means of object systems of wireless networks of complex algorithms of processing, compact coding and protection of signal samples, video data frames and measuring values, crypto- proof and noise-proof transmission of monitoring information packets directly in the places of origin of network streams. The algorithms of compression and monitoring data protection should be optimized for the speed and accuracy of data encoding, taking into account the minimization of computing operations by micro power microprocessors and microcontrollers of object systems of the Internet of Things. The reduction of information flows in places of installation of object systems of Internet networks of things is achieved on the basis of adaptation of data coding algorithms, depending on the conditions of input and the accuracy of the presentation of monitoring data and the formation of code-signal sequences of monitoring information packets with increased information capacity. Parameters of noise-proof transmission of crypto-proof information packets are selected depending on the current level of noise in the radio channel. The key characteristic of the operation efficiency of object systems of Internet of things networks is the current speed of the transmission of the compressed and protected monitoring information. With existing computing and channel resources of object systems taking into account the current conditions of input and transfer of monitoring data that are variables, the implementation of reliable and secure data transmission in networks of Internet of Things is carried out by constant support of processor means of object systems the maximum speed of packets of compressed and encrypted monitoring data. In practice, the transmission of such packets is the transmission of pseudo-chaotic break-even information
