Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] we take figure 1 The execution process of the shown multiple access method is used to illustrate the specific implementation manner of the present invention. When a nanometer node needs a certain neighbor node selected by a routing protocol to relay data flow, the rate-differentiated multiple access method of the present invention is used to access the relay node. The method consists of "access node operating steps" and "relay node operating steps".
[0034] Such as figure 1 As shown, wherein, the "access node operation steps" include the following specific steps:
[0035] Step 1: Send an access request control packet to the relay node to notify the relay node that the node has data flow to be sent to the relay node.
[0036] Step 2: Wait for the relay node to send a reply control packet, once the relay node sends the control packet, it will receive it, and ...

Disclosed is a method for low conflict rate division multiple access of a wireless nano sensor network. The low complexity interaction step of an access node and a relay node and the simple calculation on the relay node are used for achieving access control of the access node. The access node sends an access request control package to inform the relay node that novel data flow needs to be relayed and awaits the relay node to inform the symbol rate needing to be used; once the relay node receives the access request control package, the symbol rate of a minimum conflict probability is calculated, and the access node is informed of using the symbol rate to send a data package by replying one control package. The fact that the relay node is used for calculating and obtaining a formula (1) about the symbol rate of the minimum conflict probability is the core of the method for the low conflict rate division multiple access of the wireless nano sensor network. The method for the low conflict rate division multiple access of the wireless nano sensor network is very suitable for processing nano sensor nodes with low capacity, and can lower the probability of node sending conflicts in the wireless nano sensor network.
Description
technical field [0001] The invention relates to a rate-differentiated multiple access method in wireless communication, which is suitable for wireless nanometer sensor networks. technical background [0002] With the rapid development of nanotechnology, it has become possible to manufacture sensors with nanoscale size, that is, nanosensors. The network formed by interconnecting nanosensors through wireless communication technology is called wireless nanosensor network. Wireless nanosensor network has a very broad application prospect in the fields of environment, medical treatment, industry, military and so on. Since the nanosensor nodes in the nanosensor network are only about a few hundred nanometers in size and the processing power of the nanoprocessor is very limited, designing a communication protocol with extremely low complexity is one of the key issues to be studied in the wireless nanosensor network. [0003] The design of each sub-protocol of the wireless nanosen...
