Problems solved by technology

Due to the dense deployment of network nodes, the information collected by network nodes contains more redundant information, but in the above-mentioned dynamic cluster head centralized processing method, the transmission of redundant information between cluster member nodes will still bring a large additional energy consumption

Embodiment Construction

[0022] The specific steps of the wireless sensor network distributed cooperative information processing method of the present invention are as follows:

[0023] Step 1: In advance, each node in the wireless sensor network establishes its own position, target position, and intelligent body based on the maximum detection distance, maximum communication distance, residual energy, information processing algorithm performance parameters and first model parameters of each node. The potential field model of the relationship between the position of the host node and the action potential of the node on the decision-making of the agent's movement path, and at the same time, the self-activation is established according to the distance between the communication nodes, the maximum communication distance of the node and the relevant activation probability update parameters. Probabilistic update model, please refer to Fig. 1, described wireless sensor network has 10 node end (namely node 1 to...

Abstract

First, the method establishes potential field model (PFM) and activation probability update model (APUM) at each node end. Then, each node end determines current self-state based on own current sleep / activation probability. All activated node ends detect target. Host node end with intelligent body (IB) processes own collected data based on info process algorithm carried by IB in order to form intermediate result, as well as sends out own info. Receiving info sent from host node end, each node end detected the target calculates own effect potential on decision for moving path of IB respectively based on PFM as well as sends out related info. Based on the said effect potential, host node end determines the node end to be moved for next hop of IB. based on APUM and received info, each activated node end updates own sleep / activation probability so as to realize distributed coprocessing data.

Description

technical field [0001] The invention relates to an information processing method of a wireless sensor network, in particular to a distributed cooperative information processing method of a wireless sensor network. Background technique [0002] Due to its broad application prospects in military defense, industry and agriculture, urban management, biomedicine, environmental monitoring, emergency rescue and disaster relief, and anti-terrorism and anti-terrorism, wireless sensor networks have attracted great attention from the world's academic and industrial circles and triggered wireless sensor networks. Internet research boom. A wireless sensor network is a network composed of large-scale randomly arranged wireless sensor nodes or cluster points for the purpose of sensing the real physical space. However, due to the uncertainty and dynamic characteristics of physical space signals and their states, how to coordinate multiple sensor nodes and obtain correct relevant informatio...
