However, for OOK modulation with time domain expansion, when two adjacent nodes that want to start sending bit information start to send the first bit symbol at the same time, that is, the first bit transmission conflicts, then all subsequent bits Sends will collide, resulting in a large number of bit reception errors on the receiving node

Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings.
[0032] refer to Figure 1 ~ Figure 3 , a wireless nanosensor network access method based on period multiplication, the access method comprising the following steps:
[0033] Step 1: When the network is just deployed or the node is restarted, calculate the number N of bits continuously sent by all access nodes at a certain sending time point in the future according to the formula (1);
[0034]
[0035] where r min It is the minimum allowable value of the symbol rate according to network delay requirements and other aspects.
[0036] The value of α needs to meet the following conditions: 1) α min >T pkt , to ensure that the relay node has enough time to send the control packet to the access node, where T pkt is the time spent in sending control packets. Under the above conditions, the larger the value of α, the higher the channel utilization rate, but the greater...

Provided is a wireless nanometer sensor network access method based on period doubling. The access control of access nodes is finished through low-complexity interaction step of the access nodes and relay nodes and easy calculation on the relay nodes. The method comprises the steps that the number of bits every time all the access nodes are sent continuously is calculated and determined, and when a certain access node informs the relay nodes that new data flow needs to be relayed by sending one access request control package, the relay nodes calculate the sending period of the access nodes and the sending start time points and inform the access modes by replying a control package. That the relay nodes determine the sending period of the access nodes and the sending start time points in a period doubling mode is the core of the method. The method is very applicable to nanometer sensor nodes with lower processing capacity, and can avoid sending conflict of the nodes in the wireless nanometer sensor network.
Description
technical field [0001] The invention relates to an access method in wireless communication, which is suitable for wireless nanometer sensor network. [0002] technical background [0003] The wireless nanosensor network is a network composed of multiple sensors composed of nanoscale materials connected to each other through wireless communication technology. This type of network will play an important role in the fields of environment, medical treatment and industry. Due to the small size of nanosensor nodes, the energy obtained is limited, and the processing power of their processors is low, so designing a communication protocol with extremely low computational complexity is one of the key issues to be studied in wireless nanosensor networks. [0004] The sub-protocol design of each layer of the wireless nanosensor network communication protocol, including the design of the modulation mode of the physical layer and the design of the access control method of the data link la...
