Voice communication over mobile ad hoc networks
Patrick Sondi, Dhavy Gantsou · 2009
Works on voice communication over mobile ad hoc networks essentially rely on routing protocols that were originally proposed for best-effort services. However, best-effort routing is not adapted to voice communication due to real-time and quality of service constraints. In order to enable the Optimized Link State Routing (OLSR) to fulfill these constraints, we propose a QoS extension model of OLSR. This model is then evaluated using the OPNET simulator. Besides confirmation of the fact that end-to-end delay, and jitter constraints of voice applications are fulfilled, the simulation results show an improvement of the packets delivery ratio in comparison with native OLSR.
