Abstract

The invention relates to the technical field of communication, in particular to a sensor node distribution density control method based on information flow accumulation. The method mainly includes the following steps that first, according to the information flow-rate needing to be forwarded by sensor nodes at different positions in a network, the average service load condition of the sensor codes in different monitored areas is estimated; then, by the means of the average service load condition of the sensor codes, total energy consumption for sensing, receiving and sending data in different monitored areas is calculated; finally, according to the average energy consumption ratio in different monitored areas, the deployment density of the sensor nodes in all the monitored areas in the network is estimated. Through the network constructed with the sensor node distribution density control method based on information flow accumulation, the energy hole problems existing in the wireless sensor network can be effectively solved, and the method has good adjustability and can meet the requirement for energy consumption balance of the wireless sensor network and the coverage degree in the monitored areas in different environments.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a sensor node distribution density control method based on information flow accumulation. The method utilizes the energy consumption at different monitoring positions in the network to provide a highly reliable node non-uniform The deployment strategy effectively solves the problem of energy holes in wireless sensor networks. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, miniature sensors with perception, computing and communication capabilities begin to appear around the world. The wireless sensor network composed of these micro-sensors connects the logical information world and the objective physical world, so that people can directly perceive the objective world with the help of wireless sensor networks, thus greatly improving human understanding and perception of t...
