Multihop wireless relays can extend the area of network connectivity instantly and efficiently. However, due to the spatial dependence of wireless link-quality, the deployment of relay nodes requires extensive, expensive measurement, and management efforts. This paper presents a Mobile Autonomous Router System, (MARS) through which a relay router autonomously seeks and adjusts the best \"Reception\" position for itself and cooperatively forms a string -type relay network with other neighboring routers. Specifically, MARS accurately characterizes spatial link-quality through a new measurement technique, effectively probes/optimizes node positioning via a spatial probing algorithm, and maintains error-tolerant position in format ion via an inexpensive positioning algorithm.
