The basic concepts of wide band mobile ad hoc networking are used in this thesis to extend the functionality of a typical low-speed telemetry system. Although most efforts related to wireless networking are driven by the insatiable demand for high-speed mobile data applications, telemetry applications ensure the continuous wide spread use of lowspeed narrow band data networks. A multi-hop auto-routing telemetry system has the advantages of extended operational range, and portability, for nomadic monitoring, or rapid deployment applications. All stations operate both in their telemetry capacities, providing typical functionality and I/O capabilities, as well as implicit routers, supporting a DSR based protocol to achieve dynamic, multi-hop operation. While the emphasis of work described in the thesis is placed on the optimal design and development of a dynamic, multi-hop telemetry network, a further aspect presented herein is the extension of an existing state transition matrix queuing model to encompass the type of network designed. The model offers a prediction of latency performance of the multi-hop system using half duplex low speed radio links, and corresponds with measured results.
