Abstract

The Mobile Ad Hoc Network (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. There are number of reasons due to which the QoS performance is affected such as mobility and security attacks. 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. Also, due to the open nature of wireless communications, such networks are easily vulnerable to different security attacks. The goal of this paper is to present the study on recent QoS aware routing protocols and security aware routing protocols. 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 motivation for MANET QoS enhancement.
