Problems solved by technology

[0005] But this Quorum system is because all nodes in the network choose m 1 row and m 2 Therefore, the Quorum selected between nodes is homogeneous, so the working time slots selected by the nodes may be the same, resulting in increased conflicts during data transmission, reduced intersecting working time slots, and increased transmission delay

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0018] In this embodiment, the Quorum system refers to: for a given positive integer n, and a universal set U={0,1,...,n-1}, and Q={Q 1 ,Q 2 ,...Q q}, That is, Q is a subset set of U, and Q i is an element of Q. If the intersection of any two elements satisfying Q is not empty, that is Then Q is said to be a Quorum system under the universal set U={0,1,...,n-1}.

[0019] The designed F-group (p,m)(F(p,m)) is: for a given positive integer n, and a universal set U={0,1,...,n-1}. Let The F-group is expressed as F(p,m) as shown in the following formula 1:

[0020] F ( p , m ) = { ( i n + 2 m + p + j ...

Abstract

The present invention discloses a media access control method of a wireless sensor network based on a Quorum system. In the method, time is divided into time slots, and n time slots (slot) constructs one period. The present invention designs F-cliq UE and G-cliq UE, F-cliq UE or G-cliq UE, respectively; based on the design formula, some time slots are selected, a sensor node works in the selected time slots, which is referred to as the Quorum Time Slot (QTS), while the sensor node sleeps in the other unselected time slots to save energy consumption. Each node of the sensor network, based on the ring number of the ring it is at, selects F-cliq UE or G-cliq UE, the node at the ring of an odd number selects F-cliq UE, while the node at the ring of an even number selects G-cliq UE, and in this way, an MAC protocol based on the FG Quorum system is formed. It is proven through theoretical analysis that the media access control method based on the FG Quorum system of the present invention has a small network delay, and can improve the throughput of the network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a medium access control (medium access control, MAC) method of a wireless sensor network. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner, and wireless sensors are often powered by batteries as their energy source, so How to rationally utilize and allocate energy consumption is very important. [0003] Medium Access Control (MAC) protocol is a basic protocol in wireless sensor networks. Its role is to ensure the normal data operation and environmental monitoring of nodes while reducing energy consumption as much as possible, thereby maximizing the network life. In a wireless sensor network, in order to reduce the energy consumption of nodes, a method is generally adopted to allow nodes to wo...
