Multimedia applications require certain QoS guarantees to be met in order to function properly. QoS requirements for multimedia transmission include bandwidth guarantees and temporal guarantees (delay and jitter). Existing routing protocols on MANeTs are not adequate enough to deal with these necessities imposed by multimedia traffic. In this article, an adaptation of MPLS is proposed for MANeTs. MPLS and MLDP together are employed in MANeTs to provide QoS and traffic engineering for real time multimedia traffic. These protocols are implemented and tested in the OMNeT++ network simulator. This article describes in detail the design and implementation of MPLS and MLDP.
Multimedia applications require certain QoS guarantees in order to function properly. This is especially true when these applications need to run on MANeTs (Mobile Ad Hoc Networks). The movement of mobile nodes in MANeTs is not controlled rather it is random and unpredictable. Due to this dynamic topology multimedia applications cannot rely solely on traditional routing protocols to provide services for their correct working. In this paper an already existing QoS provisioning technology for wired networks.
MPLS (Multiprotocol Label Switching) has beenadapted to suit this dynamic nature of MANeTs. The framework also includes a QoS signaling protocol and flexible resource allocation and adaptation mechanisms. In order to prove its efficiency the system is implemented and simulated using the OMNeT++ network simulator.
