Method and system for network communication of wireless sensor

Abstract

The invention discloses one wireless sensor network communication method and system, which comprises the following steps: process center point sends broadcast in initial time and the point measures self and process center distance through the broadcast information; network point organism forms cluster structure and selecting cluster point front network gate and common point front cluster head in initial time; cluster member collects data in set time gap and sends to cluster head; the cluster head and front network gate transmit time gap data to process central point.

Description

technical field [0001] The invention relates to a wireless sensor network communication system, in particular to a wireless sensor network communication method and system in an underwater acoustic high delay environment. Background technique [0002] The research and development of underwater sensor network has made it play an increasingly important role in many applications, such as: data collection in oceanographic research, marine environment monitoring, underwater military monitoring, marine disaster monitoring, etc. Figure 1 is a schematic diagram of an underwater acoustic sensor network. The structure of the underwater sensor network is similar to that of the traditional sensor network on land. The sensor nodes are distributed in the environment to be monitored, and the nodes sense data. Then transfer the data to the processing center (Sink). The processing center is an object such as a buoy without any resource constraints. It should be able to directly contact the sh...

Problems solved by technology

However, most location-based wireless routing protocols, such as GRS, MFR, etc., have not carefully considered energy consumption. Some protocols only ensure that the relay node of the node is closer to the target node than itself, and do not care whether the relay node is closer to the target node than itself. The nodes themselves are further away from the source node, so they do not maximize the effective transmission distance per hop

[0006] However, due to the particularity of underwater sensor networks, these protocol methods cannot be directly applied to underwater sensor networks.
