simulHoc centerless self-organizing network technology SimulHoc has no central self-organizing network technology. It inherits the first prize of National Science and Technology Progress Award (Tsinghua University DTMB national standard) technology, and realizes multi-hop multi-level relay, same-frequency simultaneous broadcast network and signal overlap and other integration. The technology perfectly realizes the centerless self-organizing communication network, and solves the technical problem of multi-point simulcast forwarding and overlapping area signal interference. The performance indicators of this technology have reached the US military standard, enabling ultra-long-distance communication without relying on the existing public network and private network, and creating a flexible and mobile centerless network communication system. The simulHoc centerless ad hoc network technology does not require routing. Multiple nodes automatically decide whether to initiate forwarding by receiving signal quality and field strength, and promote the relay from the network layer multi-hop single-point relay to the physical layer multi-hop multi-point relay. The trunk is upgraded from the linear trunk to the mesh relay, and the intelligent relay is performed on the received signal quality and the field strength automatic judgment at the physical layer, and multi-point signal combining is performed, thereby greatly improving the coverage effect and the transmission distance. simulHoc technical features 1, single jump distance is excellent The technology is derived from digital TV broadcasting technology, with a very low signal-to-noise ratio threshold (1dB) and a receiving sensitivity close to the Shannon limit (-128dBm), achieving a 50% increase in communication distance at the same transmit power. 2, no routing to achieve multi-level mesh relay, the network self-healing ability is excellent The technology is to perform relay networking through the physical layer. Communication between network nodes does not require routing, and any node leaving or joining does not affect the communication of the entire network. 3. Dynamically changing network topology The technology is based on ultra-high-speed synchronization and signal processing technology, and communication establishment and dynamic network topology convergence can be completed in 1 millisecond. The self-organizing network terminal can be moved in the network at any speed and in any manner. The network topology between the terminals can be changed at any time, and can be flexibly deformed, folded, and reconstructed to meet the flexible mobility of the user. 4, support for multi-point merge transmission The technology supports multi-point combined transmission data, and does not generate overlapping area interference, forming a single frequency network with the same frequency simulcast, and the receiving node can combine signals from different forwarding nodes to greatly improve the coverage distance and communication. Reliability. 5, high security, unique encryption communication. The technology uses a completely autonomous communication baseband, coupled with the AES256 encryption algorithm, the communication transmission has a very high confidentiality. 6, three-dimensional networking Special areas such as large buildings, multi-storey basements, tunnels, and mines are limited by factors such as wired resources and complex building structures. Ground signals cannot be directly transmitted to the underground, while SimulHoc has no central self-organizing network technology to automatically relay wireless networking through portable terminals. The hopping forwards the incoming signal to quickly achieve ground and underground interworking. Technical comparison 1. The traditional wireless relay networking technology must rely on the designated relay device (with center). Once the relay device is damaged or powered off, the entire network faces embarrassment. simulHoc has no central self-organizing network technology, and each node can assume the relay function. The integrity of the entire network does not depend on a certain node. 2. The MESH networking technology increases the hop count as the number of hops increases; simulHoc has no center-advanced network technology, and the delay of multi-hop transmission can be neglected. The more nodes in the same range of MESH networking, the better the communication quality will be. The more nodes with the same range of simulHoc technology, the better the quality and coverage of communication. 3. The trunking communication system must rely on the base station to achieve large-scale coverage. In many cases, it is impossible to set up a fixed or mobile trunking communication base station. SimulHoc has no central self-organizing network technology, which can realize multi-hop transmission through a portable handheld terminal or a piggyback base station, achieving a wide range of communication coverage. simulHoc technology application 1. Tunnel wireless communication scheme By utilizing the multi-hop transmission characteristics of the technology, a handheld terminal is used in a shorter tunnel, and a piggyback base station is used in a long tunnel to implement wireless communication. 2. Tethered drone long-distance communication scheme By utilizing the multi-hop transmission characteristics of the technology, the two handheld terminals are carried out by the unmanned aerial vehicle as a relay, and the B-segment coverage of the three-segment coverage can be 50-80km, plus 30-50km of the A and C sections. A total of 110-180km of communication coverage can be achieved. 3. Mountain wireless communication scheme By utilizing the multi-hop transmission characteristics of the technology, a handheld terminal or a piggyback base station can be placed on two hills to realize a wide range of mountain wireless communication. Application field Internet of Things, individual soldier systems, emergency communications, emergency broadcasting, drones, robots, real-time remote control, etc. Related Products Micro Site® Self-organizing Network Interphone The micro-site access network walkie-talkie does not depend on any relay equipment, and builds a centerless self-organized communication network, covering 2 to 3 times the coverage of the traditional walkie-talkie, providing clearer voice call effects and member location sharing.
