Abstract

In this paper, we propose a new approach for Quality-of-Service routing in wireless ad-hoc networks called rmin-routing, with the provision of statistical minimum route reliability as main route selection criterion. Discovery of rmin routes is based on a network model with statistical link reliabilities, which are combined into path reliabilities. To achieve specified minimum route reliabilities, we improve the reliability of individual links by well-directed retransmissions, to be applied during the operation of routes. To select among a set of candidate routes, we define and apply route quality criteria concerning network load. We have applied rmin -routing in sample topologies, and compare it to other routing approaches.
