Mobile Ad-hoc NETworks (MANETs) is an appealing technology that has attracted lots of research efforts over past years. Although, the principle of wireless, structure-less, dynamic networks is attractive, there are still some major flaws that prevent commercial expansion. QoS is one the main issue in today's multimedia technology. In this paper, the authors purposed a model i.e., priority based weighted queue QoS model in MANETs. Model is implemented in NS-2.34 and results are compared with other models.
