Embodiment Construction

[0064] At present, there are various MAC protocols in wireless sensor networks, and there are more than 30 mainstream protocols. But in its essence, it is the coordination and management of how multiple nodes in the network access the channel, nothing more than ALOHA-based MAC protocol, CSMA-based MAC protocol and TDMA (Time Division Multiple Access, Time Division Multiple Access) the MAC protocol.

[0065] in:

[0066] ALOHA-based MAC protocols include: slotted / non-slotted ALOHA protocol, slotted / non-slotted ALOHA protocol sent with probability p, and slotted / non-slotted ALOHA protocol with acknowledgment.

[0067] CSMA-based MAC protocols include: p-persistent slotted / non-slotted CSMA protocol, 1-persistent slotted / non-slotted CSMA protocol, slotted / non-slotted CSMA protocol with handshake mechanism, and slotted with acknowledgment / non-slotted CSMA protocol etc.

[0068] The TDMA-based MAC protocol includes: a pre-assigned access mechanism implemented in a certain way. ...

Abstract

The invention discloses a generating method for a media access control (MAC) protocol, comprising: preprocessing step to determine a basic access mechanism, to set multiple extension functions according to user needs, and to select configurable parameters for each extension function; and generating step to determine the content is the extension functions corresponding to the configurable parameters of preset data, when a user configures the configurable parameters according to an objective MAC protocol, to load code and decode the selected expansion functions and the basic access mechanism, thus generating the objective MAC protocol. The invention also discloses a device for implementing the method, an inter-node communication method and a wireless multi-hop network. The embodiment of theinvention solves the problems of non-generality and compatibility of the prior art, which are caused by the close coupling of a protocol and user needs.

Description

technical field [0001] The present invention relates to the field of wireless network technology, and more specifically, to a method and device for generating a MAC (Media Access Control, Media Access Control) protocol in a wireless multi-hop network, and a method and device for node communication based on the method for generating the protocol. Background technique [0002] In the wireless network, there is a wireless multi-hop network, and the wireless multi-hop network can be an ad hoc network or a sensor network. [0003] Let’s take the sensor network as an example to illustrate: [0004] The sensor network is composed of a large number of tiny sensor nodes integrating wireless communication, information collection and information processing functions. Each sensor node uses its own sensor to collect the information of the surrounding environment, and then transmits the information to the data aggregation node (also called the Sink node) in the network. Since there are ...
