Evaluación de desempeño de VoIP en redes MANET

MANET networks are an attractive option for VoIP solutions in scenarios that are characterized by the mobility of nodes and where there is not a previously established infrastructure. However, the voice support faces more rigorous challenges in MANET networks than those of others networks. The dynamic with which topology changes affects important parameters to measure quality  such  as  delay,  packet  loss  and  delay  variation. In  this  work  we  measured  the  impact  of  metrics  such  as  hop  count,  traffic  load,  node  density  and  number  of  route  breaks  have  over  the  performance  of  VoIP  applications in MANET through simulation. Such simulations have  allowed  the  comparison  of  the  behavior  of  three important  routing  protocols. From the results reached, it has been shown that the studied metrics have a more unstable behavior in MANET than in other networks that are  also  candidates  to  carry  mobile  services.  However, there is a lot of expectation with the possibility of using these  technologies  (VoIP  and  MANET)  to  provide low-cost  mobile  telephony  due  to  the  ease  of  deployment and simplicity of its infrastructure.
