IPv4 Vs IPv6 QoS: A challenge in MANET
Sanjeev Kumar Sharma, Sanjay Sharma · 2014
Mobile Ad Hoc Network (MANET) is collection of mobile nodes that communicate with each other without centralized control or established infrastructure. Due to rapidly deployable and Infrastructure less nature we can utilized MANET in various scenario like Earth quack, Military scenarios, Emergency/rescue operations, Students on campus, Free Internet connection sharing, Conferences etc. In current scenario various real-time applications like Audio/ Video or Internet protocol television (IPTV), Voice over IP (VoIP) , Videoconferencing ,Online transactions etc. are sensitive to network performance parameters like IPDV, throughput and drop , that's why we need to enable the network capability to provide better quality of service becomes very important. Current IP networks provide best effort traffic delivery to providing partial guarantees in terms of Quality of Service. However, there are services, including voice, with strong requirements for delay and delay jitter, which makes it necessary to add functionality to IPv4 networks in order to gain support for such services. IPv6 was developed due to the problems of IPv4 as above mentioned. In this paper we describe the various QoS models and mechanism that are used to provide QoS on a network. We also describe various QoS parameters. Then after we specify the features that use both IPv4 and IPv6 to implement QoS. Finally, we present the performance comparison of IPv4/IPv6 in MANET.
