Shaping Throughput Profiles in Multihop Wireless Networks: A Resource-Biasing Approach
A fundamental question in multihop wireless network protocol design is how to partition the network's transport capacity among contending flows. A classically "Fair" allocation leads to poor throughput performance for all flows because connections that traverse a large number of hops (i.e., long connections) consume a disproportionate share of resources. Specifically, mixing strongly biased allocations with fairer allocations leads to efficient network utilization as well as a superior trade-off between flow throughput and fairness. The authors present an analytical model that offers insight into the impact of a particular resource allocation strategy on network performance, taking into account finite network size and spatial traffic patterns.
