Abstract

Mobile ad hoc networks (MANET) are characterized by bandwidth constrained wireless links, multiple hops and highly dynamic topologies. Providing QoS support in MANETs is hence a challenging task. This paper presents the design, implementation and evaluation of INORA, which is a network layer QoS support mechanism that makes use of the INSIGNIA in-band 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.
