Abstract

The IEEE 802.11 DCF protocol used in multihop networks with chain topologies does not provide fair throughput to each node due to the hidden/exposed terminal problem and edge node effect. Eliminating the contention from hidden nodes is the key to providing high performance in the mesh network. We propose a token-based distributed scheduling scheme that not only guarantees throughput fairness among nodes but also allows allocation of proportional throughput among nodes.
