Since IEEE 802.11’s characteristics are vulnerable to
Denial of Service (DoS) and greedy behavior. DoS are made by a mobile node to degrade the performance of the network or to consume the network resources. Greedy behavior can also degrade the network performance.
Detecting these problems within a network layer may be easy and can let attackers by-pass the security mechanisms. In our approach, we propose a cross-layer security architecture which considers interactions between layers.
To propose the security mechanisms dealing with Denial of Service attacks and greedy behavior in mobile Ad-hoc networks using IEEE 802.11 technology.
Our work consists of several subtasks:
- Define attack models.
- Define a cross-layer security architecture.
- Study of the detection mechanisms.
- Study of the reaction mechanisms.
- Develop detection mechanisms and reaction mechanisms that consider local knowledge within a layer and global knowledge across layers.
- Develop a simulation model for testing the mechanisms.
- Compare the proposed approaches with existing approaches.
