Fuzzy Optimization for Mobile Ad Hoc Networks: A Bottom-up Cross-Layer Approach

In this paper, the authors introduce a new method for cross-layer design in mobile ad hoc networks. They use Fuzzy Logic System (FLS) to coordinate physical layer, data-link layer and application layer for cross-layer design. Ground speed, average delay and packets successful transmission ratio are selected as antecedents for the FLS. The output of FLS provides adjusting factors for the AMC (Adaptive Modulation and Coding), transmission power, retransmission times and rate control decision. Simulation results show that their cross-layer design can reduce the average delay, increase the throughput and extend the network lifetime. The network performance parameters could also keep stable after the cross-layer optimization.
