Evaluation of QoS Metrics in Ad Hoc Networks with the use of Secure Routing Protocols
Darlan Vivian, Eduardo Alchieri, Carlos Becker Westphall · 2006
An Ad Hoc nework is formed by mobile computer (nodes) with wireless interfaces that communicate amongst themselves without the help of any infrastructure. Due to their characteristics, the Ad Hoc networks are prone to the presence of malicious nodes that can degrade your performance. This fact motivated the appearance of security protocols that implement mechanisms to avoid attacks like DoS. In this article is accomplished a verification the impact caused in the performance of the Ad Hoc networks with the use of security protocols (SEAD and Ariadne) in relation to the use of protocols that don't have security mechanisms (DSDV and DSR). Firstly an Ad Hoc network is simulated using these routing protocols and soon afterwards a comparative study is accomplished through graphs of the values obtained for each basic QoS metrics.
