Description

The invention relates to the field of communications and telecommunications, and more specifically to a digital communication method with a fixed connectivity parameter.

The present invention may find application in the creation of systems and networks of global and regional communications and data transmission.

Currently, for the organization of communication systems and networks that require coverage of large territories, either geostationary communication satellites or low-orbit satellite constellations are used, or an extensive network of base relay stations, which are high-rise structures, is created on the territory.

However, these methods have a number of significant drawbacks. First of all, this is a high load on the base stations, which connect all subscribers located in the coverage area of the base station. Further, for communication with a remote satellite or base station, a high transmitter power is required, the radiation of which negatively affects the person who owns the subscriber device, and also increases the general electromagnetic background, which negatively affects other people and natural objects. In addition, the high power of the transmitters leads to a significant consumption of energy sources of subscriber devices, such as batteries of mobile and satellite phones. Finally, the ability to communicate subscribers only through base stations or satellites leads to a significant dependence of the operability of the communication network on the operability of base stations or satellites, which may be damaged or intentionally turned off, and, accordingly, to periodic unavailability of communication services for individual subscribers.

Closest to the present invention is the Eurasian patent application EA200900909 A method of digital electrical or optical communication with a variable transmitter power level for the operation of a network of electrical or optical communication subscribers, according to which for the operation of a network of electrical or optical communication subscribers, consisting of at least two transmission cycles and receiving subscribers, each of which is characterized by a unique identifier and has at least a transmitter and a receiver, as Like the above method, the first subscriber sets the signal level of the transmitter to minimum power, after which, at a fixed transmitter power level, the first subscriber sends a request for the presence of other subscribers in the network, after which the first subscriber proceeds to receive data, and the other subscriber, upon receipt of the request, in the transmission cycle sends a response to the request containing the identifier of the specified other subscriber and a list of identifiers of the subscribers with whom the specified other subscriber is currently communicating en; and in the absence of answers to the request for the availability of other subscribers in the network, the power level of the transmitter of the first subscriber rises and the request for the presence of other subscribers in the network is repeated, and such increases in power level and repeated requests occur until a response is received from at least one other the subscriber, the identifier of the specified other subscriber and the list of identifiers of the subscribers with which the specified other subscriber is currently connected, are stored and used to transmit data directly specified to another subscriber or related subscribers and / or receiving data directly from the specified other subscriber or related subscribers, after which the transmitter power of the first subscriber is reevaluated, consisting in the fact that the transmission signal power is reduced to a minimum level that ensures stable communication with subscribers with whom it was possible to establish a connection.

However, this method has some disadvantages, namely:

it is not possible to achieve a high probability of the possibility of transferring data from an arbitrary subscriber to an arbitrary one (up to 75-80% in the specified prototype), the implementation of the method requires very significant computing power and significant overhead traffic for transmitting identifier chains.

The basis of the present invention is the creation of a digital communication method with a fixed connectivity parameter, free from the disadvantages of the above prototype, which would achieve a high probability of the possibility of data transfer from an arbitrary subscriber to an arbitrary one (up to 90-95%) and would not require significant computing power and significant overhead traffic for the transfer of identifier chains.

This problem is solved in the method of a digital communication method with a fixed connectivity parameter, according to which, for the operation of the network of subscribers of electrical or optical communication, consisting of at least two transmitting and receiving subscribers, each of which is characterized by a unique name or number and has at least least a transmitter and a receiver, characterized in that the subscriber network is characterized by a minimum connectivity parameter, which is equal to the number of subscribers with which any subscriber can communicate of the communication system, in accordance with which each subscriber stores the identifiers of subscribers with whom he can communicate at a given time and when receiving digital data destined for another subscriber, redirects this data to the subscriber connected to him directly or in transit through other subscribers, moreover transmitter power or sensitivity of the subscriber receiver is changed in such a way as to maintain communication with a given number of subscribers, not less than the minimum connectivity parameter.

To demonstrate the effectiveness of the proposed approach, the following experimental model of a communication system was created. It is a cyclically performed procedure that simulates a communication network of several subscribers (in the experimental sample, the parameter Ν_ΑΒ), the EO functions tactlessly for a single network time.

Subscribers are initially randomly placed inside a square of size N by N conventional units (in the experimental sample, the parameter POE) and move at some points in time. To move, a random number of subscribers is selected, characterized by the SIK_MOUE parameter.

At the initial moment of time, each transmitter is assigned a certain transmitter power, also set in arbitrary units.

Coefficient of individual connectivity - a value that characterizes the number of subscribers with which each subscriber is connected directly, is determined by the parameter θυΚ_ΟΟΝΝΕΟΤ, which is set for initial debugging and modeling 4. The limit of individual connectivity ΜΑΧ_ΟΟΝΝΕΟΤ is also set in the EA.

Information on the current state of the subscriber’s transceiver devices and their current location is located in the HopepC database, the structure of which is as follows:

// abopep18 [1] [0] - the coordinate X of the ί-το subscriber // abopep15 [Л [1] - the coordinate of the Υ ί -th subscriber // abopep1k [Ts [2] - the power of the transmitter а // abopepy [|] [ 3] - transit throughput

The criterion for the possibility of communication of one subscriber with another is the fact that the power of its transmitter, expressed in arbitrary units, is not less than the distance between these subscribers.

At each point in time, the system checks the possibility of communication between one randomly selected subscriber and another randomly selected subscriber, either directly or through another subscriber, and a positive or negative result of this check is recorded. The resulting parameter is a statistical assessment of the connectivity of a pair of randomly selected subscribers.

When moving subscribers, it is checked whether the power of the subscriber’s transmitter is excessive in order to maintain stable communication with those subscribers with whom communication has already been established. In the case of redundancy, the power is reduced so that already established connections would not be lost.

For example, with the number of subscribers 15 and the size of the field 50, the modeling results for 2200 steps with a connectivity parameter of 6 are given in Appendix 1. It is easy to see that the method supports exceptionally high quality communications (95% of successful connections), and also reduces the energy consumption of subscribers due to load balancing and extends the use of transmitter power supplies. The value of Tour1 indicates the number of subscribers who managed to transfer data directly, Tour2 indicates the number of subscribers who managed to transfer data through one subscriber, and Tour2 indicates the number of subscribers who managed to transfer data through two subscribers.

Compared with all communication methods known to the authors, the present invention is characterized by a significant increase in the availability of communication network subscribers and a decrease in the power of transmitters and the general electromagnetic background, lower energy consumption, and no need for base stations.
