A network self-organization method for multiple ecological observations

Abstract

The invention proposes a network self-organization method oriented to multiple ecological observations. The invention designs a node model of a multi-interface directional antenna; designs a message packet for discovering adjacent nodes, a one-hop neighbor information table and a two-hop neighbor information table; discovers three detections of adjacent neighbors; designs a time-division multiplexing method combined with a directional antenna Time slot allocation method; design control message; design channel allocation algorithm. The invention greatly improves the reuse rate of space, can overcome the shortcomings of traditional ecological monitoring such as message loss and time delay increase caused by multi-hops, and has great significance for improving the quality of field ecological monitoring.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a network self-organization method for multi-ecological observation. Background technique [0002] Due to the influence of the geographical environment in the wild, the locations of the monitoring sites are scattered and far away. The inspection environment of the field operators is often in a no-man’s land, and there is almost no ground communication network, which has a huge impact on the work and life safety of the operators and hidden dangers. , In the event of danger or special discovery in field operations, it is necessary to establish contact with the Administration in time to report the situation or ask for help. In addition, in order to improve the work efficiency of field operators, they need to transmit data, files, voice, video and other information in a timely manner, and cannot rely on fixed basic communication facilities. Therefore, there is an urgent need ...

Problems solved by technology

However, the common disadvantage of the above two monitoring methods is that in the mesh network and WMSN network, the data is forwarded by multiple hops through the intermediate nodes, and each hop will bring at least some delay. The more it is, the greater the accumulated total delay will be. For media applications with high communication requirements such as voice and video, there is no problem of too long transmission and reception delays.

When multiple messages are transmitted concurrently on the same channel, collisions may occur, resulting in the loss of messages and reducing the throughput of the network. Therefore, an optimized channel resource allocation method is needed to allow each message within limited network resources. Each message is correct and arrives quickly
