Efficient algorithm and study of QoS-aware mobile Ad hoc network methods

Now a day's use of wireless communication is very common and growing faster. There are different types of wireless networks which are designed as per the requirement of data rate and coverage. In this paper scope is limited to widely study and used network called Mobile Ad hoc Network (MANET). MANET is collection of wireless devices which communicate among each other without need of any physical infrastructure as well as centralize administrations. Each mobile node in MANET acts as peer node. The communication is MANET is based on routing methods and hence since from last 2 decade there are number of routing methods designed with objective of improving the Quality of Service (QoS) performance of MANET. As the mobile nodes in MANET are moving randomly with varying mobility speed, this can leads the challenging tasks to achieve the guaranteed QoS performance. Therefore it is required to have efficient routing protocol with load balancing and dynamic behaviour of mobile nodes handling in MANET. In this paper, our goal first is to present the study on different QoS aware routing methods and non-routing methods designed by various research groups for MANET. Second objective is to design novel QoS Aware routing protocol for improving the QoS performance in MANET. Additionally, we are presenting the current research gap based on analysis of all recent methods of QoS improvement. The outcome of this paper is the current research problems and efficient QAODV routing method.
