— Mobile ad hoc networks (MANETs) provide a powerful and dynamic platform to enable mobile computers to establish communications without an existing infrastructure. In order to provide support for multimedia applications, Quality of Service (QoS) support becomes an important component in their design. Research is being conducted to design routing protocols in MANETs that contain QoS support features and capabilities. However, the research in this area is still in its early stages. In this paper, we present a dynamic range bandwidth reservation protocol for TDMA-based MANETs. In this protocol, a source node S, that needs to send data, sends a request message (QREQ) to reserve a QoS path to the desired destination node D. In the reservation message, the source node specifies a dynamic range [bmin, bmax] of the number of slots needed to transmit the data. The intermediate nodes along the path try to reserve a number of slots, bcur, that is equal to the maximum number of slots that are ...
