Wireless ad hoc network communication method based on single-soldier cooperative combat

Abstract

The invention discloses a wireless ad hoc network communication method based on single-soldier cooperative combat. Each single soldier is regarded as a node in a wireless ad hoc network, and a node closest to the remaining nodes is selected in multiple nodes through an optimal path algorithm to be regarded as a relay node. A communication base station and a cloud server are also included. Information transfer is carried out between the wireless nodes through the relay node. The relay node is updated and replaced in real time. Wireless nodes in a communication radius range R transfer single-soldier combat information to a cloud server end through the communication base station, and combat command information is returned through the cloud server and transmitted among the wireless nodes. Battlefield long-range and short-range ad hoc network communication is realized. An improved destination sequenced distance vector routing (DSDV) protocol is adopted for networking among the wireless nodes, a traditional destination sequenced distance vector routing protocol is combined with an ant colony algorithm for networking, and the nodes exchange information with neighboring nodes thereof through a routing information protocol (RIP).

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a wireless ad hoc network communication method based on individual soldier cooperative operations. Background technique [0002] The wireless ad-hoc network is composed of nodes and is an autonomous, multi-hop network. The entire network has no fixed infrastructure and can be used when the existing network infrastructure (such as base stations, APs (Access Points)) cannot be used or is inconvenient. In the case of , it provides intercommunication between nodes. Due to the limited transmission power and wireless coverage of nodes, if two nodes that are far away from each other want to communicate, they must use other nodes to forward packets. In this way, a wireless multi-hop network is formed between the nodes. Mobile nodes in the network have routing and packet forwarding functions, and can form any network topology through wireless connections. A wireless ad hoc network...

Problems solved by technology

There is such a problem in the prior art: the size of the sequence number is set here based on the priority made when the next hop is a single hop. For an ad hoc network, its distribution is a tree distribution. When the top node of the tree will When the information is transmitted to the leaf nodes, the distribution between each leaf node is scattered, so it is a complex multi-hop distribution. The size of the sequence number alone cannot be the first selection factor for priority transmission. It is possible that the sequence number is small but Its branches are longer, and the next hop is closer to the root node (that is, the node within the wireless communication range of the base station in the wireless ad hoc network), that is, there is a situation where the node has more priority for communication; the serial number broadcast by the node is monotonically increasing Even number, when node B finds that the route to node D (routing sequence number is s) is interrupted, node B broadcasts a routing information, notifying that the sequence number of the route becomes s+l, and sets the number of hops to infinity, so , the routing table of any node A that sends information through B includes an infinite distance, this process until A receives a valid route to D (the route sequence number is s+1-1)

DSDV requires the routing table to be updated frequently, which still consumes energy and network bandwidth when the network is idle

Once the network topology changes, a new serial number will be generated; therefore, standard DSDV cannot be applied to rapidly changing networks, so it is very important to provide an improved DSDV routing protocol for ad hoc networks

The existing wireless ad-hoc network is not suitable for single-soldier combat. When fighting alone in the field, it is often encountered that there is no indoor satellite communication signal or the signal is extremely weak. At this time, for the situation that requires coordinated communication in the field In other words, the original self-organizing network system is powerless, and there is a situation where the network is single and the coordination is not good enough.
