چکیده

A Wireless Sensor Network (WSN) is a collection of thousands of tiny sensor nodes having the capability of wireless communication, limited computation and sensing. These networks are vulnerable to internal and external attacks due to the lack of tamper-resistant packaging and the insecure nature of wireless communication channels. Since most of the existing routing protocols are application specific and hence do not satisfy the security constraints of wireless sensor networks. Whenever any device comes within the frequency range can get the access to the transmitting data and may affect the transmission. In this paper, we simulated the concept of frequency hopping and proved it a better approach to provide security in WSN..

LPKP: location-based probabilistic key pre-distribution scheme for large-scale wireless sensor networks using graph coloring

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
