Extending the AODV Protocol to Provide Quality of Service in Mobile Ad hoc Networks
Voice communication is the most needed application in disaster management. However, without good QoS tuning, its performance can be poor. QoS routing is one of the most important building blocks in any given QoS solution. To conceive a QoS routing protocol for ad hoc networks, we can either conceive a new protocol from scratch, or extend an existing best effort protocol like AODV (Ad-hoc On-Demand Distance Vector Routing Protocol). The main advantage for the second approach is its easiness. In this paper, we propose a new QoS routing protocol that can satisfy multimedia application requirements in ad hoc networks. Thereafter, we present and discuss simulation results obtained under the NS-2 simulator for a VoIP application.
