QoS Routing Protocol of Mobile Adhoc Network – A Brief Introduction

Abstract

In communication networks, delivering quality-of-service (QoS) at the network layer is a significant difficulty. This is especially true for mobile ad hoc networks (MANETs) in the context of ambient intelligence (AmI), given the rising popularity of bandwidth- and delay-sensitive applications. For a mobile network to connect to wired networks that offer QoS, the QoS routing capability is crucial (e.g., ATM, Internet, etc.). For real-time applications, the QoS routing protocol can also be used in a standalone mobile ad hoc network. Such a routing protocol notifies the source (or ATM gateway) of the bandwidth and QoS made accessible to any mobile network destination. This information makes it possible to establish QoS connections within the mobile network and to support real-time applications effectively. Additionally, it makes call admission control more effective. The Mobile Adhoc Network (MANET) is a collection of several autonomous nodes that can move around freely and are linked together via wireless technology. Due to its ease of installation and lack of dependence on established infrastructure, MANET is becoming more and more common in both civil and military applications. High Quality of Service (QoS) requirements for these applications include minimal wait time, high throughput, and high packet delivery ratio (PDR). Any MANET must have as its primary requirement those protocols that satisfy the QoS standards. Many academics have recently introduced several QoS-based protocols.
