Ad hoc networks have characteristics such as flexibility, fast and easy deployment, and robustness which make them an interesting technology for various applications.Adhoc networks are considered as the most promising terminal networks in future mobile communications.Providing sufficient bandwidth and time delay for multimedia applications in ad hoc networks is an urgent task because of the rising popularity of multimedia applications and potential commercial usage of adhoc networks.Providing QOS(Quality Of Service) guarantee is a critical and challenging problem in ad hoc networks because of multihop, mutual radio interference and node mobility.This paper focuses on QOS metrics: maximum bandwidth and minimum delay.While general approaches are available in literature that can't work better for MANET where node life time is much smaller.This paper proposes a protocol QMPRP(QOS-aware Multiple Path Routing Protocol) to find out QOS oriented multiple paths to avoid reestablishment of paths in case node failures, The results are graphically shown and compared with existing models, the proposed model out performs the existing models in a significant way for frequent node failures. General TermsThis paper exposes a protocol QMPRP, for finding QOS oriented optimal multiple paths for a pair of source and destination nodes.
