Modern mobile ad-hoc networks (MANETs) frequently consist of nodes which exhibit a wide range of autonomy needs. Bandwidth limitation and dynamic topology of MANETs are prime challenges to support QoS in MANETs. Therefore, to propose a unique scheme that support’s best QoS in MANETs suitable for all application scenarios is a challenging task. Keeping this in mind and to overcome the limitation, this paper makes an effort to investigate QoSin MANETs, from an internet application perspective that supports active calls of users roaming from cellular or WLANs. Here parametric measurements such as upstream and downstreamthroughput, network joining delays, end-to-end frame delivery delays are of primary importance.. A lot of research has been done on supporting QoS in MANETS. Some of the main QoS provisioning protocols are DSR, MP-DSR, ASPA, and TDMA. But none of these considers Node utilization factor. This protocol takes bandwidth as the QoS parameter, and considers handling capacity of effective paths and guaranties QoS service by introducing node utilization factor and path utilization factor. The algorithm of route discovery and Route maintenance in the protocol is extension of DSR protocol and QMR/PR Protocol.

A Mobile Ad-hoc Network (MANET) is a type of wireless ad hoc network, and is a self-configuring network of mobile devices connected by many wireless links. Every device in a MANET is also a router as it is required to forward traffic unrelated to its own use. Each MANET device is free to move independently, in any arbitrary direction, and thus each device will potentially change its links to other devices on a regular basis. The primary challenge for building a MANET is for each device to continuously maintain the information required to properly route traffic. MANETs are broadly classified into three types they are Vehicular Ad-Hoc Networks(VANET), Intelligent Vehicular Ad-hoc Network (InVANET) and Internet Based Mobile Ad-hoc Networks (iMANET). They differ based on the applications used. This paper reports a study of various MANETs.
