The nature of wireless multihop ad-hoc networks makes it a challenge to offer connections of an assured quality. In order to improve the performance of such networks, multipath routing in combination with Multiple Description Coding (MDC) has been proposed. By splitting up streams of multimedia traffic into several substreams (called descriptions), by sending these substreams along different paths from the source to the destination, and by reassembling them again at the destination, the quality of the received stream may be improved as compared to the single-description, single-path case. This paper presents a simulation study of the combination of MDC and multipath routing from a network perspective with a realistic medium access control protocol (IEEE 802.11) and a widely used routing protocol.
