TL;DR

This paper proposes an integrated security framework for wireless sensor networks that combines multiple security components and introduces an Intelligent Security Agent to adapt security levels across all network layers.

Contribution

It introduces a comprehensive security framework with an Intelligent Security Agent that manages cross-layer security interactions for sensor networks.

Findings

Framework tested on three application scenarios

Includes intrusion detection, trust management, and key schemes

Validated using Castalia and Omnet++ simulators

Abstract

Security concern for a Sensor Networks and level of security desired may differ according to application specific needs where the sensor networks are deployed. Till now, most of the security solutions proposed for sensor networks are layer wise i.e a particular solution is applicable to single layer itself. So, to integrate them all is a new research challenge. In this paper we took up the challenge and have proposed an integrated comprehensive security framework that will provide security services for all services of sensor network. We have added one extra component i.e. Intelligent Security Agent (ISA) to assess level of security and cross layer interactions. This framework has many components like Intrusion Detection System, Trust Framework, Key Management scheme and Link layer communication protocol. We have also tested it on three different application scenarios in Castalia and Omnet++ simulator.
