Abstract

The invention relates to a wireless directional relay communication method and system. The method comprises the following steps: receiving and parsing a data packet by a relay node, wherein the data packet comprises a sending address, a relay address, a destination address, and data information; judging whether the relay address in the data packet is an address of a nearest relay node located in front of the relay node in a pre-determined relay path, and if yes, then modifying the relay address in the data packet into the relay address of the current relay node, and forwarding the data packetafter the relay address is modified to the next relay node in the current transmission direction according to the pre-determined relay path; otherwise, no processing is carried out. The wireless directional relay communication method provided by the invention can achieve long distance transmission through a relay mode, and the relay node only forwards a task data packet, and does not deal with other received data packets, so as to avoid occupying the bandwidth.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a wireless directional relay communication method and system. Background technique [0002] Ningxia is a large agricultural province with 1.145 million hectares of arable land and 2.82 mu of arable land per capita, which is higher than the national average. Ningxia has good conditions for the development of agriculture. However, Ningxia is located in the arid region of northwest China, and water resources are relatively tight. The main source of irrigation water is The Yellow River, the water conservancy related projects of the Yellow River are directly related to the foundation of industrial and agricultural development in Ningxia. [0003] Accurate regulation and management of water resources is the premise of realizing the rational use of water resources. The mouth of the Yellow River irrigation canal, especially the discharge gate of the main canal leading to the bran...
