Abstract
Ad hoc wireless network has been a most active research area for its flexibility in network construction. In ad hoc networks, contention-based MAC protocols, such as IEEE 802.11, are popular since they are easy to implement. However, these contention-based MAC protocols do not coordinate between nodes at different hops within a multi-hop flow. It has been pointed out that the 802.11 MAC cannot discover the optimum schedule of multi-hop transmissions. Distributed priority scheduling, a technique that piggybacks the priority tag of a node’s head-of-line packet onto handshake and data packets; e.g., RTS/DATA packets in IEEE 802.11. By monitoring transmitted packets, each node maintains a scheduling table which is used to assess the node’s priority level relative to other nodes. It incorporates this scheduling table into existing IEEE 802.11 priority back-off schemes to approximate the idealized schedule. In this paper we discussed medium access control and distributed priority scheduling concepts.
