Description

The invention relates to the field of wireless communications.

A known method of implementing packet transmission from base stations to a mobile device according to patent RU 2526751 - an analogue containing steps in which:

The transmission of the information packet from the base station at the relay station is received, wherein the transmitted transmission of the information packet has a common reference signal for use in decoding the transmission of the information packet, wherein the transmission of the information packet is formatted in accordance with a subframe format having a control area and a data area;

A control signal and said common reference signal are transmitted from the relay station to the mobile device, and these control signal and common reference signal are transmitted in the control area of the mentioned sub-frame format in multi-interval packet transmission, while the mobile device is configured to use this common reference signal to perform analysis for measuring and evaluating channels in relation to packet transmissions received from the relay station.

The disadvantage of the above analogue is the high load on the relay station, according to energy parameters and, if necessary, the transmission of signals from a large number of devices, since only one relay station is used, it is not possible to transmit signals from analog types of devices.

A known method of creating a wireless multi-hop network according to patent RU 2510156, selected by the authors as a prototype, which contains many devices (0, 1, 2, ..., 96) in the device layout, and in this device method (1, 2, 3, ..., 96) create a physical wireless connection with at least one other device (0, 1, 11, 16, 17, 29, 30, 39, 52, 53, 55, 64, 71, 73, 79, 88) of the network the process of self-organization, and in the process of self-organization, the search device intending to join the network listens for beacon signals from taught by candidate parent devices already on the network, containing the network identifier and the device identifier of the radiating devices, in the process of selecting the parent object, the search device selects the parent device among the candidate parent devices in accordance with the specified selection rules based on the network identifiers (EPIDs) , receiving capabilities of candidate parent devices, and communication quality parameter values related to the search device and parent candidate devices, moreover, in the process of selecting the parent object, connection data is applied at the application level searching for the device and / or parent devices, and the searching device is connected physically through the selected parent device (0, 1, 11, 16, 17, 29 , 30, 39, 48, 52, 53, 55, 64, 71, 73, 79, 88) to the network;

wherein the search device sends a request signal to devices already on the network, and each of a certain number of parent candidate devices that receive the request signal emits a beacon signal.

The disadvantage of the prototype is the use of a constantly active repeater that transmits beacon signals, which leads to high power consumption of the equipment, as well as limited operational capabilities, namely in case of failure of one of the "parent devices" (hereinafter referred to as repeaters), some of the devices will not be able to communicate with by others, it is additionally necessary to increase the reliability of the network, and it is also not possible to convert any type of electrical signal into digital form by le obtain from the device via radio transmission, converting the original type, and sending to the device without any modifications of the respective devices).

The objective of the claimed method is the direct provision of a more intelligent way of organizing the network, allowing for redundant communication between devices due to the presence of repeaters in each device, as well as increasing the scope, extending directly not only to digital and discrete signals, but also to analog ones, supplementing repeaters - signal converters (converting standard wired interfaces into a radio channel), additionally distributing priority between signals.

The problem is solved by a method of creating a wireless network containing many devices, which consists in the fact that in this method a physical wireless connection is created for each device due to the presence of a relay in it with at least one other network device in which the application-level connection data contain a set of identifiers of other relays with which the device should be connected, searching for devices containing network identifiers and devices intending to connect connect to the network, characterized in that the repeaters are placed in each device, while during the absence of information the repeaters are in standby mode, a converter of any type of electrical signal (wire interface) from the device to the radio signal is installed in each relay, this information is sent to another device through its repeater and control the transmitted information, in the absence of a physical wireless connection between two devices between which information is required to be transmitted, information is transmitted through intermediate or intermediate relays, in accordance with the “network tree” laid down in the relay, when information does not arrive on one of the repeaters, the information is sent again from the previous one, if there is insufficient information about the control of the transmitted information after repeated or several repeated messages, the information is sent along another route in accordance with the “network tree”, when receiving two signals at the same time the first signal is transmitted with the highest priority in accordance with the "network tree", if possible, signals with lower priority are transmitted along another route in accordance with the established "network tree".

To increase the reliability of the network, it is planned to create a physical wireless connection with at least two other network repeaters, the data transfer between which is carried out on the basis of the network tree, through repeaters having physical wireless connection. If there is no return response to the repeater, it is possible to re-send data or switch to another route in accordance with the network tree.

To prioritize, in advance, the priorities of each device are laid in the network tree, and when two or more signals are received on one repeater, it is transmitted first with the highest priority. Signals having the same priority and arriving after receiving a similar signal are transmitted through a secondary route, if any, in the absence of a signal is transmitted in turn.

Blocking of adding devices is allowed.

BRIEF DESCRIPTION OF THE DRAWINGS

In FIG. 1 is a structural diagram of a particular case of communication between device 1 and device 3, in which the wired connection is replaced by a radio channel through repeaters 1p and 3p, respectively. In the absence of a physical wireless connection between device 1 and device 3, data is transmitted through a repeater 2p, with each device being a relay for another.

In FIG. Figure 2 shows a block diagram of communication between devices where data is required to be transmitted along a previously laid route from device 1 to device 2 in the absence of a direct physical wireless connection between device 1 and 2 through the corresponding route (which is determined for each device separately). In this case, data transmission is carried out through a set of repeaters (A ... B), each of which is connected to the corresponding device.

In FIG. 3 presents a special case of a structural diagram of the availability of a physical wireless connection between a number of devices, namely:

Device 1 has a physical wireless connection to device A due to repeaters 1p, B, and A, provided that there is no direct physical connection between A and 1p, the network route is defined as 1p-B-A.

Device 1 has a physical wireless connection with device 2 at the expense of repeaters along the path 1p-В-2р, if relay B is busy or the priority of the signal is lower than that already transmitted - device 1 has an additional way for transmitting a signal to device 2, which is determined network tree and in this example is a route 1p-S-2p.

The claimed method allows you to implement a more intelligent method of network self-organization, which allows for redundant communication between devices due to the presence of repeaters in each device, as well as increasing the scope, extending directly not only to digital and discrete signals, but also to analog ones, supplementing repeaters with converters ( converting standard wired interfaces to a radio channel), additionally distributing priority between signals, further increasing the reliability of forms sending repeated messages in case of unsuccessful sending, as well as transmitting along the backup route in case of its availability.
