VQAPM: voice quality assurance protocol in MANET

We introduce a new protocol called VQAPM to assure quality voice in VoIP perspective when communicating nodes are the part of some MANET. We use two specific parameters of voice communication over IP: one is voice codec and the other is IP packet length. A node in MANET is selected as MVCH (MANET Voice Communication Head) that applies the proposed algorithm to determine an optimum combination of bit rate and packet length and assigns it to the requesting node for a VoIP session to ensure efficient voice quality. VQAPM considers the congestion factor in multiple route MANETs and is applied on the best available path determined through a traffic allocation algorithm keeping in view the level of congestion on the route so that overall efficiency of the system is not compromised. Our simulation study reveals that VQAPM increases voice quality in a communication session when results are obtained for a few key metrics of Quality of Service.
