Embodiment Construction

[0035] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 Shown is a flow chart of a method for improving the invulnerability of a wireless sensor network in the present invention, specifically including:

[0037] Step 1: Divide the overall WSN network into k subnets by using a clustering algorithm combined with an iterative method;

[0038] Step 2: For the k subnets divided in the step 1, use the mode of finding a balance point to find the aggregation nodes in each subnet respectively;

[0039] Step 3: Give the multi-hop multi-center network invulnerability evaluation method and combine the results obtained in step 2 to evaluate the overall invulnerability performance of the network.

[0040] The purpose of the present invention is to be able to improve the invulnerability performance of the multi-hop multi-center network and evaluate the overall invulnerability performance...

Abstract

The invention discloses a method for improving survivability of a wireless sensor network. The method mainly includes the first step of dividing the whole WSN network into k subnets through a clustering algorithm and iteration combined method, the second step of calculating sink nodes in each subnet through an equilibrium point calculation method for the k subnets obtained through division in the first step, and the third step of putting forward to a multi-hopping multi-center network survivability detecting and evaluating method to evaluate the overall survivability of the network through combination with the results obtained in the second step. The method is suitable for the complex wireless sensor network which has the multi-hopping multi-center characteristic and is provided with the nodes obviously different from one another in the aspects of service types, data volumes and the like, and the survivability of the network of this type can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to the design of a method for improving the invulnerability of wireless sensor networks. Background technique [0002] Wireless sensor network is a special Ad-Hoc network, which is a complex system integrating data acquisition, data processing and data transmission. It consists of many randomly distributed sensors with wireless communication modules, data processing modules, sensor modules and power modules. node composition. Because the sensor network is composed of a large number of nodes in a self-organizing manner, and the network conditions are limited, the energy of the nodes is limited, and the layout environment is harsh, so the robustness, reliability, and adaptability to the environment in the design of the sensor network have become sensors. Issues that must be considered in network design. With the continuous expansion of WSN network scale ...
