Centralized Trust Based Secure Routing in Wireless Networks

Centralized Trust Based Secure Routing in Wireless Networks


Wireless networks are vulnerable to various network attacks. To cope with these security issues, trust-based routing schemes have emerged. Typically, trust routing schemes are mainly focused on detection of packet drop attacks, because this type of an attack is simple and obviously a malicious behavior. However, there are more advanced attacks, such as, false trust reporting or compromised attacks, where trust-based routing to defend these attacks is more difficult because of their ambiguous behavior. In order to ensure data transmission reliability even against such attacks, in this letter a centralized trust based secure routing (CSR) scheme is proposed for wireless networks. Simulation results show that the CSR scheme provides a better performance compared to the ATR and SPR schemes.
