A Method for Source Location Privacy Preservation in Sensor Networks Based on Branch Fusion Energy Harvesting

Abstract

The invention discloses an energy collection sensor network source position privacy protection method based on branch confluence. According to the method, through predicting energy which can be collected in an energy collection period, a principle of 'make ends meet' is used to fully utilize collected energy as possible so as to create more interference source nodes, and the maximization of privacy protection is realized. An area far from a base station has a lot of routing branches and at the same time has abundant energy, the area is called a non-hot area, and an area which is near to a convergence node is called a hot area. According to the privacy protection routing method of branch confluence, routes are converged into a few routes before reaching the base station, thus the transmission burden of nodes in the hot area in a sensor network is reduced, and the energy utilization rate of the network is significantly raised while the network privacy protection strength is raised.

Description

technical field [0001] The invention belongs to the field of wireless sensor networks, and in particular relates to a method for protecting the privacy of sensor network source locations based on branch fusion energy collection in the wireless sensor network. Background technique [0002] The energy harvesting wireless sensor network refers to the network in which the nodes in the network can collect and supplement energy through the surrounding environment (such as solar energy, wind energy, thermal energy, etc.). Because its energy is renewable, it can be applied to unmanned Long-term monitoring in important and complex environments. Security issues have always been one of the key issues that need to be solved in the development of sensor networks, and one of the important security issues is the privacy protection of source nodes. The so-called privacy protection of source nodes refers to hiding the location of source nodes in wireless sensor networks. After the event sou...

Among them, the method often used to defend against global attacks is to use a type of algorithm based on a flooding algorithm, which consumes a lot of energy

Fortunately, it is generally difficult for an attacker to achieve global attack vision. It requires extremely expensive equipment, but it is very easy to expose the attacker himself by using extremely conspicuous equipment.
