A position-based key management scheme for heterogeneous sensor networks

Abstract

Wireless sensor networks have many applications in the areas of commercial, military and environmental requirements. These networks face a lot of security challenges for reasons such as insecure communications and wireless communications. How to manage the cryptographic keys between sensor nodes deployed in the network in order to make maximum security with minimum cost as a basic approach in securing these networks has attracted attention of researchers. Therefore, in this paper by using the position of the sensor nodes as part of their identity, a novel method for key management in heterogeneous sensor networks have been proposed.
