Energy collection sensor network source position privacy protection method based on branch confluence

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, in particular to a method for privacy protection of source location privacy of sensor networks based on branch-converging energy collection in wireless sensor networks. Background technique [0002] Energy harvesting wireless sensor network refers to a network in which nodes existing in the network can realize energy collection and supplementation through the surrounding environment (such as solar energy, wind energy, thermal energy, etc.). Because of its renewable energy, it can be applied to unmanned operation. Long-term monitoring in important and complex environments. The security issue has always been one of the key issues to be solved in the development of sensor networks, and one of the important security issues is the privacy protection issue of source nodes. The so-called privacy protection issue of source nodes refers to hiding the location of source nodes in wireless sensor netw...

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.
