The Node Reliability Approach to Broadcasting in Manets: Raising Reliability With Low End-to-End Delay
Talmai Oliveira, Fabíola Greve · 2007
This paper evaluates how well a significant number of broadcasting protocols for MANETs behave when under a realistic scenario of momentary failures and topology changes, which is represented by an omission fault model. Reliable protocols which use additional mechanisms to ensure higher delivery rates beyond best- effort guarantees - have been proposed, but they exhibit unacceptably high end-to-end delays. As a result of the study conducted, a new mechanism that helps to enhance the reliability of deterministic broadcasting protocols is proposed. The mechanism allows for scalability, and is capable of ensuring good delivery rates (in spite of failures) while maintaining lower end-to-end delays. Simulation results demonstrate the efficacy of the mechanism.
