| Popis: | The communications inside MANETs usually show frequent disruptions due to changes in topology and the condition of having a shared physical channel. It is necessary to implement a mechanism to maintain connectivity and ensure Quality of Service (QoS). In this paper we introduce a route recovery mechanism for a QoS routing protocol called AQA-AODV (Adaptive QoS-Aware AODV) which is an extension of the AODV protocol. Our proposal provides a mechanism to detect the link failures in a route and reestablish the connections taking into account the conditions of QoS that have been established during the route discovery phase. The simulation results reveal performance improvements in terms of packet delay, number of link failures and connection setup latency while the end-to-end throughput is not affected compared with the throughput achieved by other protocols like AODV. |
