SERVICE INDEX-BASED FAIRNESS PACKET SCHEDULING METHOD IN WIRELESS AD-HOC NETWORKS

摘要

A service index-based fairness packet scheduling method in a wireless ad-hoc network is provided to minimize the reduction of a network throughput because service tag information to be exchanged is not necessary when packet scheduling such as time-stamp type WFQ(Weighted Fair Queueing) is applied to ad-hoc packet scheduling. An amount of a service received by flows of each node is calculated to set a flow service index and a node service index. The calculated node service index is exchanged with neighbor nodes. A back-off value of a MAC(Media Access Control) layer is set by the exchanged node service index.
