Problems solved by technology

[0004] However, several issues need to be paid attention to in the application: 1) The communication distance of sensor nodes is limited
Therefore, only sensors within a certain distance can communicate; 2) The storage capacity and channel capacity of sensor nodes are limited

specific Embodiment approach 1

[0024] Specific implementation mode 1. Combination figure 1 Describe this specific embodiment, the wireless communication method based on the distributed Gossip algorithm of quantitative consensus, it is characterized in that: in the wireless sensor network that comprises N nodes, N is a positive integer, its wireless communication method is:

[0025] Step 1. Initialize the state value of each node in the network, and set the appropriate number of iterations (it may not be set in practical applications);

[0026] Step 2. In the tth time slot, randomly wake up node i, and use node i as an initiating node; i is an integer greater than or equal to 1 and less than or equal to N; the initiating node i broadcasts itself in the wireless sensor network state value x i (t);

[0027] t is a real number;

[0028] Step 3. In the wireless sensor network, all nodes whose Euclidean distance to node i is less than its connection radius R are used as receiving nodes, and the set of all rece...

Abstract

The invention relates to the field of wireless communication, in particular to a wireless communication method based on a quantization consensus distributed Gossip algorithm to guarantee final consensus state in communication of nodes in the wireless communication network after quantization. The method includes: randomly waking up a node i at a tth slot time, broadcasting the state value of the node i in the wireless communication network; enabling adjacent nodes of the node i to receive the state value, subjecting the state value and local state information values of the adjacent nodes of the node I to weighted average calculating operation and quantization, and taking the quantization result as a new state value of the receiving node; and after certain iterations, achieving the consensus state when the state values of all nodes in the network are consistent, so that wireless communication based on the quantization consensus distributed Gossip algorithm is realized. The method is applicable to wireless communication process.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless communication method based on a quantitative consensus distributed Gossip algorithm. Background technique [0002] With the development of wireless technology, the electromagnetic environment of human life has become more and more complex, and in many cases it is necessary to collect, monitor, analyze and process information. The wireless sensor network is composed of a large number of cheap micro sensor nodes deployed in the monitoring area. The sensor network provides people with the most direct, effective and real information. It has the characteristics of rapid deployment, strong invulnerability, and real-time performance, and has more and more extensive application prospects. [0003] An important problem in a distributed system network is that the nodes all reach a consensus state. This consensus protocol includes distributed consensus and synchronization ...
