SURVEY OF QUALITY OF SERVICES TO IMPROVE PERFORMANCE OF ROUTING IN MANET
Journal Of Harmonized Research in Engineering
A mobile ad hoc network (MANET) consists of mobile wireless nodes. The communication between these mobile nodes is carried out without any centralized control. The ease of deployment and the infrastructure less nature of Mobile Ad hoc Networks (MANETs) make them highly desirable for the present day multimedia communications . Within the last couple of years there has been a tremendous increase in the use of wireless networks which have provided internet connectivity to mobile devices,
... ile devices, creating the need for supporting real-time communication applications on highly mobile network environments. Within the wireless networks domain, Mobile Ad hoc networks (MANET) have become very popular. Abstract: Ad hoc Networks (MANETs) make them highly desirable for the present day multimedia communications. Traditional routing protocols may not suffice for real time communications it depends upon the conditions and our requirements. Though there has been considerable research in this area. MANETs are being used in numerous application domains from emergency rescue and relief to networks. To support real-time communications (such as audio and video) over MANETs, new Quality of Service (QoS) provisioning mechanisms need to be developed. There are many challenges in QoS provisioning for MANETs such as dynamically changing topology, wireless capacity limitations, heterogeneous network environment, limited battery power etc. Previous QoS surveys in MANET have only looked at QoS provisioning models, signaling and routing. This paper presents a complete survey of the challenges and current state of the art of MANET QoS Routing. We include a thorough overview of QoS routing metrics, resources, and factors affecting performance and classify the protocols found in the respective topics.
