Label Switch Path with guaranteed Quality of Service in Mobile Ad Hoc Network

The increasing use of MANETs for transferring multimedia applications such as voice, video and data, leads to the need to provide QoS support. This paper introduces a resource reservation-based label switch path, Label Switch Path with guaranteed Quality of Service (LSPQS) that provides end-to- end quality of service support, in terms of bandwidth, link loss ratio and end-to-end delay, in mobile ad hoc networks. The establishment of LSP allows for forwarding of data below IP layer and encapsulation of variety of MAC protocols. To provide guaranteed QoS along LSP detailed working out is presented to allow estimation of available bandwidth, link loss ratio and end-to-end delay in unsynchronized wireless environment. LSPQS also includes efficient mechanisms for QoS maintenance, including temporary reservation and fast recovery processes.
