| Sumario: | Mobile ad hoc networks (MANETs) are self-configuring, dynamically adaptable networks of heterogeneous devices, some of which can assume the role of routers. Meanwhile, mobile computing is an increasingly pervasive technology worldwide, thus positioning MANETs as a very suitable technology for disaster scenarios. This article addresses the problem of guaranteeing a minimum operational infrastructure for critical communications over MANETs, while allowing non-critical clients to use the infrastructure only under a best-effort scheme. Non-prioritized nodes are expected to absorb the drawbacks of poor connectivity during eventual periods of congestion. This appears as a desirable Quality of Service (QoS) mechanism in contexts of emergency with limited, unstable network resources. We present CB-AQM, a novel approach for QoS in MANETs. The strategy relies on an Active Queue Management (AQM) scheme implementing client node prioritization using OLSR as the base routing protocol. We show that it can efficiently and dynamically allow non-prioritized clients to use the network without incurring in major perturbations to the QoS assigned to prioritized clients. © 2016 IEEE. |
