Encryption of data transmitted through structure-free wireless sensor networks

الملخص EN

Recently, the technology has been developed and wireless networks have received great interest in drawing the world's attention to the family.

Wireless sensor networks are a set of sensor nodes specific resources that collaboratively working on the transfer or follow different phenomena(Chemical and physical) such as (sound, heat ...

etc) and then transmit the information monitored wirelessly by connecting sensor nodes with each other until they reach the base station.

There are two types of building mechanisms for wireless sensor network (WSN);structure-based and structure-free.

The first is suffering from many problems which can be overcome when dealing with the other type.

Most of the environments that deal with wireless sensor networks are difficult to reach and dangerous.

Therefore, they are subject to many security breaches.

These violations can lead to severe consequences and difficult to deal with in case they occur.

Therefore, security must be provided through the network in one way or another taking into account that achieving security through the network is not easy because of the resources identified, especially as the security is the main issue and the first in many applications.

In this paper, the structure-free typeis applied and in order to achieve security, data transmitted through the network is encrypted using the Elliptic Curves Diffie-Hellman(ECDH) and the RivestShamir-Adleman(RSA) algorithms.Simulation results demonstrate that the power consumption of the structure-free wireless sensor network with data encrypted by ECDH and RSAalgorithms.The results show that the power consumption by ECDH algorithm is better that RSA type with nearly 13%.
