adaptive routing in mobile ad hoc networks based on decision aid approach
In this paper, we propose a new approach to the problem of adaptive routing in small scale Mobile Ad Hoc Networks (MANET). The proposed approach focuses on leveraging the already existing routing algorithms in real-time through switching from one routing algorithm to another as the conditions change. The contribution of this work is three-fold: (1) nodes use a Multiple Criteria Decision Analysis method called PROMETHEE to make local decisions, (2) the final decision is evaluated as an aggregation of all the local decisions in the MANET through weighted voting, and (3) the network-wide decision process is carried out through a hybrid method that aims to benefit from the advantages of centralized and distributed methods, while limiting their disadvantages. The analyses based on the results extracted from simulations underline that the proposed approach produces stable configurations with minimal interruptions. Furthermore, the completion of global adaptation cycles are performed an order of magnitude faster in comparison to the results outlined in the previous work. These results indicate that the proposed solution is a promising alternative to the existing solutions, and forms a strong basis for further research on larger scale MANETs.
