INORA- A Unified Signaling cum Routing Mechanism for QoS Support in Mobile Adhoc Networks

Abstract

Mobile Adhoc Networks are characterized by bandwidth constrained wireless links, multiple hops and highly dynamic topologies. Thus, providing QoS support in MANETs is a challenging task. This paper presents the design, implementation and evaluation of a network layer QoS support mechanism which makes use of the INSIGNIA inband signaling mechanism and TORA routing protocol for MANETs. TORA provides multiple routes between a given source and destination. We present an effective coupling between TORA and INSIGNIA to get routes that are "best-able" to provide QoS requirements for a flow. INORA also combines congestion control with routing.
