A Top-down Hierarchical Multi-hop Secure Routing Protocol for Wireless Sensor Networks

This paper proposes a new top-down hierarchical, multi-hop, secure routing protocol for the wirelesssensor network, which is resilient to report fabrication attack. The report fabrication attack tries togenerate bogus reports by compromising the sensor nodes to mislead the environment monitoringapplication executed by randomly deployed wireless sensor nodes. The proposed protocol relies onsymmetric key mechanism which is appropriate for random deployment of wireless sensor nodes. In theproposed protocol, base station initiates the synthesis of secure hierarchical topology using top downapproach. The enquiry phase of the protocol provides assurance for the participation of all the clusterheads in secure hierarchical topology formation. Further, this methodology takes care of failure of headnode or member node of a cluster. This protocol ensures confidentiality, integrity, and authenticity of thefinal report of the monitoring application. The simulation results demonstrate the scalability of theproposed protocol
