  • Topical issues of application of time-frequency synchronization equipment on the communication network of Russia

    At present, only the equipment for clock synchronization is regulated on the Russian communication networks from the Frequency-Time Provision equipment. At the same time, not only frequency (clock), but also frequency-phase and time- frequency synchronization is already widely used on the unified telecommunication network of Russia, for the implementation of which new types of equipment are required. And the functions of the synchronization equipment have been considerably expanded due to the use of time synchronization signals in the distribution of clock synchronization signals over the packet communication network. In addition, in the near future on the cellular communication network is expected to introduce the standard of communication 5G. Application this standard requires to ensure the divergence of time scales of base stations within 150-250 ns, which, in turn leads to the need to upgrade the corresponding synchronization equipment. The task of this paper is to show how the requirements for the functionality and technical characteristics of the equipment of the private sector change, and how this process needs to be prepared.

  • Service Level Agreements when Providing Synchronization Signals

    One of the ways to organize the system of network synchronization in a digital telecommunication network is the use of synchronization signals received from a synchronization network of another operator. The operator providing synchronization signals service must guarantee the quality of these signals corresponding to the agreed class of connection and the dependability of their receipt. An effective and proven tool for providing such guarantees in the field of information and communication technologies is the Service Level Agreement (SLA) concluded between the provider and the customer of the service. It sets out the requirements for service quality indicators, the obligations of the parties, and, as a rule, financial responsibility of the service provider to meet the requirements. Such agreements are used in the provision of various services; they are considered in a number of international and Russian normative documents (ITU-T Recommendations, ETSI and TM Forum guidelines, GOST R). This paper describes the key aspects of SLA application and gives recommendations for their use when providing synchronization signals. In this case, the quality of the provided synchronization signals must meet the requirements for the agreed class of connection. It is recommended to use the availability as a dependability indicator, which determines the allowable total downtime for a given evaluation period (usually a month). A formula is proposed that expresses the dependence of the relative amount of financial compensation in case of a violation of the availability requirement on the severity of the violation and the required level of availability, which can be used as a technically justified guide in elaboration and evaluation of SLA conditions.

  • Multi-hop clock synchronization based on robust reference node selection for ship ad-hoc network

    Ship ad-hoc network (SANET) extends the coverage of the maritime communication among ships with the reduced cost. To fulfill the growing demands of real-time services, the SANET requires an efficient clock time synchronization algorithm which has not been carefully investigated under the ad-hoc maritime environment. This is mainly because the conventional algorithms only suggest to decrease the beacon collision probability that diminishes the clock drift among the units. However, the SANET is a very large-scale network in terms of geographic scope, e.g., with 100 km coverage. The key factor to affect the synchronization performance is the signal propagation delay, which has not being carefully considered in the existing algorithms. Therefore, it requires a robust multi-hop synchronization algorithm to support the communication among hundreds of the ships under the maritime environment. The proposed algorithm has to face and overcome several challenges, i.e., physical clock, e.g., coordinated universal time (UTC)/ global positioning system (GPS) unavailable due to the atrocious weather, network link stability, and large propagation delay in the SANET. In this paper, we propose a logical clock synchronization algorithm with multi-hop function for the SANET, namely multi- hop clock synchronization for SANET (MCSS). It works in an ad-hoc manner in case of no UTC/GPS being available, and the multi-hop function makes sure the link stability of the network. For the proposed MCSS, the synchronization time reference nodes (STRNs) are efficiently selected by considering the propagation delay, and the beacon collision can be decreased by the combination of adaptive timing synchronization procedure (ATSP) with the proposed STRN selection procedure. Based on the simulation results, we finalize the multi-hop frame structure of the SANET by considering the clock synchronization, where the physical layer parameters are contrived to meet the requirements of target applications.

  • Synchronization of wireless sensor networks using a modified IEEE 1588 protocol

    A method of precise time synchronization of wireless sensors employing an IEEE 802.15.4 transceiver, and specifically employing the 6LoWPAN protocol, was developed. It uses the IEEE 1588 synchronization standard and the IEEE 1451.5 Smart Transducer Data standard. A Wireless Transducer Interface Module (WTIM) was designed and fabricated. It utilizes the IEEE 802.15.4 transceiver model TI CC2430 which allows access to a hardware sync signal. The difference in timestamps between two WTIMs was measured. The results show that the synchronization precision is better than 10 μs for short synchronization intervals but increases to about 100 μs for longer synchronization intervals (1 sec for crystal accuracies of 50 ppm). The method was tested for 6LoWPAN wireless protocol but would apply to other wireless sensors based on the IEEE 802.15.4 protocols.

  • Research on Time Synchronization Technology of Wireless Sensor Network

    Time synchronization technology is the key support technology of wireless sensor networks. It is the core mechanism to ensure the cooperation of nodes in sensor networks. The traditional time synchronization algorithm is not suitable for wireless sensor networks.

Finally, the development trend of time synchronization technology is prospected.

  • Global sample synchronization trigger

    Synchronization measurement is very useful for power systems on phase measurement, fault location detection and others. This paper describes the concept of a frequency generator module to be used on synchronized acquisition systems. The frequency generator is modeled using a Numeric Controlled Oscillator (NCO) and a PI controller feeding back with phase error of one pulse per second (1-pps) output. The synchronization uses 1-pps from a GNSS as a reference for the synchronization system.

  • Machine learning approach on synchronization for FEC enabled channels

    Within the problem of modern synchronization systems there are is a task of system synchronization based on structure of information being transmitted over the noisy channel. Here is given a relevant example for the channel with forward error correction codes (FEC enabled channel). The method being redefined here is based on FEC data structure of the transmitted information which includes redundant symbols, and machine learning approach which is using this redundant information to detect synchronization and synchronize the whole system with less spare date being transmitted over the channel, which usually being used for synchronization purposes. Suggested redefined method of synchronization takes more computation efforts and more memory for computation, but on the other hand it set an area for its implementation in terms of complexity of synchronizing machine versus data transmission rate: both being pushed by the level of noise. Implication of machine learning mechanism is giving a great improvement on top of the produced result, providing much better performance for the whole end-to-end system, dramatically decreasing delays of taking decision on synchronization, or extending the range of the system use by improving applicability of the system over higher levels of noise. For wired telecommunication systems this leads to better quality, but for wireless systems it leads to wide range or use or/and better quality. Use of reviewed approach for FEC enabled channels leads to new result for synchronization problems solving. Moreover, proposed approach might provide better decoding level due to soft decisions being forward from synchronization module into decoding module of receiving system.
