Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in detail:

[0029] Such as figure 2 As shown, the link layer needs to use the CSMA-CA algorithm when sending data, and needs to use the CSMA-CA algorithm to access the channel before sending data frames and command frames. In order to reduce traffic in the future, the confirmation frame does not need to use the CSMA-CA algorithm.

[0030] The implementation of the CSMA-CA algorithm requires a unit time called "backoff period". A backoff period BackoffPeriod is defined as a randomly generated period of time, and the unit is milliseconds (ms).

[0031] The data link layer needs to maintain 2 variables each time it tries to send: NB and BE. NB is the number of random backoffs performed by the CSMA-CA algorithm during the attempt to send the current frame. At the beginning of each new CSMA-CA algorithm, the NB shall be initialized to 0 before it is ready to transm...

Abstract

The invention discloses a micropower wireless self-organized network broadcast communication method. According to the micropower wireless self-organized network broadcast communication method, the technology which combines the CSMA-CA algorithm with the TDMA algorithm is adopted according to the characteristics and problems of micropower wireless self-organized network broadcast communication, and communication efficiency can be improved under the condition that the reliability of broadcast communication is fully improved. Due to the fact that the slot time synchronization algorithm is put forward based on the TDMA, a node is made to have a unique slot time. Due to the fact that the slot time synchronization algorithm is adopted for broadcast data, a child node is made to start a slot time timer when receiving of broadcast data frames is finished, accurate synchronization of the timing for transmitting the broadcast data frames is achieved, and thus collision occurring during data transmission can be avoided to the maximum degree.

Description

technical field [0001] The invention belongs to the field of micropower wireless ad hoc network communication, in particular to a micropower wireless ad hoc network broadcast communication method. The invention is used to solve the problem of micro-power wireless ad hoc network broadcast communication. Background technique [0002] At present, in the fields of electric power collection, smart home, Internet of Things and other fields, the advantages of micro-power wireless ad hoc network communication technology have been recognized by more and more customers, and their use is becoming more and more extensive. [0003] In the field of low-voltage power collection, the micro-power wireless self-organizing network is a communication network that realizes the aggregation, transmission and interaction of low-voltage power users' electricity consumption information. The coverage is limited, the transmission power is strictly limited by the national radio management, the position...
