Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0036] A networking system for wireless ad hoc network multi-to-one data reporting, the networking system is composed of a convergence node and a plurality of terminal nodes, the convergence node receives the data reported by the terminal nodes, and the signal of the convergence node covers All terminal nodes; the data sent by the remote terminal node needs to be forwarded by the adjacent terminal node to reach the sink node.

[0037] The networking system adopts the characteristics of unequal signal coverage between the aggregation node and the terminal node, and peer-to-peer signal coverage between terminal nodes for networking. The aggregation node is equipped with a high-power wireless communication module, and the transmitted signal is full cov...

Abstract

The invention provides a wireless ad hoc network many-to-one data reporting method and networking system, based on a networking system composed of an aggregation node and a plurality of terminal nodes, signals of the aggregation node cover all the terminal nodes, and the method comprises the following steps: the aggregation node sends a count-off instruction; after receiving the count-off instruction, the terminal nodes count off one by one according to the ID sequence of the terminal nodes; and after the counting is finished, the aggregation node senses the existence of all the direct connection terminal nodes and part of the secondary connection terminal nodes, and broadcasts the collected information of the direct connection terminal nodes. The method has the advantages of being fast in networking, high in network state controllability and capable of reducing power consumption.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a networking system for wireless ad hoc network many-to-one data reporting. Background technique [0002] In the prior art, each terminal spends a certain amount of time monitoring whether other terminals are already transmitting on the channel before transmitting. As the number of terminals increases, the monitoring time for random backoff must be lengthened to avoid collisions as much as possible. The main problem of this scheme is low channel utilization and low transmission efficiency. In order to avoid collisions caused by simultaneous transmission of multiple terminals as far as possible, the prior art generally adopts CSMA+random backoff. The terminal node of the wireless network collects the data, forwards it step by step, and reports the data to a sink node. In the network form of this many-to-one wireless cascade networking, when the number of termi...
