3. • A sensor node wirelessly sends messages to a
base station via multi-hop path

4. • Security of WSNs
• Trust Aware Shell :
A robust trust aware routing framework for dynamic
WSNs
provides trustworthy and energy-efficient route
effective against harmful attacks

5. • Hackers aggravate network conditions
• A traditional techniques does not address the
severe problems:
tampering nodes
create traffic collision
drop or misdirect messages in routes
jam the communication channel by creating radio
interference

6. • Protect WSNs from the harmful attacks exploiting
the replay of routing information
• Centres on trustworthiness and energy efficiency
• Allow existing routing protocols to incorporate our
implementation
• No tight time synchronization & known geographic
information

15. High Throughput
Energy efficient
Scalable
Adaptable

16. Low Latency
No Balanced Network Load
Denial-Of-Service Attacks cannot be addressed

17. Mobile Target Detection in the Presence of an
Anti-Detection Mechanism
Authenticated Routing
Node-to-Node Key Agreement
Secure Military Application
Healthcare Application
