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 wireless sensor network, which is resilient to report fabrication attack. The report fabrication attack tries to generate bogus reports by compromising the sensor nodes to mislead the environment monitoring application executed by randomly deployed wireless sensor nodes. The proposed protocol relies on symmetric key mechanism which is appropriate for random deployment of wireless sensor nodes. In the proposed protocol, base station initiates the synthesis of secure hierarchical topology using top down approach.
