Problems solved by technology

[0003] In order to solve the problem of low transmission efficiency in which a handshake only allows a pair of nodes to transmit data in underwater scenarios and the large end-to-end delay caused by long propagation delays, the present invention provides a competition with a parallel transmission mechanism. The design of the permanent MAC protocol, when the receiving node receives the competition information of multiple nodes, it will calculate a sending sequence table for each sending node, each node transmits data according to the sending sequence table, realizes concurrent transmission of nodes, and improves network performance

Embodiment Construction

[0010] specific implementation plan

[0011] The present invention provides a competitive MAC protocol with a parallel transmission mechanism. Under a specific network topology, when a receiving node receives competition information from multiple nodes, it will calculate a sending sequence table for each sending node. Each node transmits data according to the sending sequence table, realizes concurrent transmission of nodes, improves the throughput of the network, and reduces the end-to-end delay of the network.

[0012] The proposed competitive MAC protocol is aimed at the water wireless sensor network communication scenarios under three specific topologies. The network consists of multiple subnets, and each subnet has multiple common nodes and one or more sink nodes SN. Collect information such as temperature, depth, and salinity in the ocean, and send the collected information to SN, and SN forwards the information to the surface gateway. The topological structure of all s...

Abstract

The invention designs an MAC (Media Access Control) protocol suitable for an underwater wireless sensor network, namely a competitive MAC protocol with a parallel transmission mechanism, the MAC protocol design mainly comprises the following steps: establishing a network model: the network is composed of a plurality of subnets, each subnet is provided with a plurality of common nodes and one or more sink nodes SN, the subnets are provided with three topological structures in total, the time is divided into time slots with the same size; the common nodes under the three topological structures send related information to different sink nodes; and the sink nodes under different topological structures carry out corresponding scheduling according to the received related information.

Description

technical field [0001] The invention belongs to the technical field of underwater wireless sensor network communication, and relates to a competitive MAC protocol. Background technique [0002] In recent years, with the application of underwater wireless sensor network in more and more fields, the research on it has been paid more and more attention by researchers. As a branch of wireless sensor networks, it has many similarities with traditional wireless sensor networks since its inception, but unlike traditional wireless sensor networks, the application scenarios of underwater wireless sensor networks are underwater, which leads to underwater The design of wireless sensor networks faces enormous difficulties. MAC protocol design is a particularly important part of network protocol design. It allows multiple nodes to transmit data on the same channel without collision, and has an important impact on network throughput, end-to-end delay, and packet loss rate. Traditional M...
