Prevention of denial of service attacks and selfishness in mobile ad hoc networks

Countermeasures against denial of service attacks and node misbehaviour
are mandatory requirements in MANET. Essential network operations assuring basic
connectivity can be heavily jeopardized by nodes that do not properly execute their
share of the network operations. We suggest a security mechanism based on a
collaborative monitoring technique that prevents active and passive denial of service
attacks by enforcing node cooperation. This mechanism can be smoothly extended to
basic network functions with little impact on existing protocols. We also investigate
on some attacks scenarios in order to analyze the robustness of the proposed security
scheme.
