Performance analysis of differentiated resource-sharing in a wireless ad-hoc network

We model and analyze a relay node in a wireless ad-hoc network. The available capacity is used to both transmit traffic from the source nodes towards the relay node and to serve the traffic at the relay node (i.e. forward it to a successor node). In this paper we consider the situation that the relay node obtains a share of the capacity that is m times as large as the share that each source node receives. The main performance metrics considered are the workload at the relay node and the average overall flow transfer time, i.e., the average time required to transmit a flow from a source node via the relay node to the destination. Our aim is to find expressions for these performance metrics for a general resource-sharing ratio m, as well as a general flow-size distribution.
