Performance issues for VoIP call routing in a hybrid ad hoc office environment

This paper extends previous work on the impact of the number of hops on the quality of VoIP applications running over wireless multihop networks. The paper also proposes a framework for analyzing the performance of route re-discovery procedures in terms of the time that the communication is disrupted due to this process and the recency, or the time that it takes to the user to 'forget' about the disconnection. The paper provides numerical and experimental data showing the relation between the voice codec used and the different design options that should be taken during deployment. Additionally, the paper proposes an application layer aggregation strategy that improves the maximum number of VoIP calls that can be supported in a wireless multihop network.
