Wireless access is becoming technology of choice in the first hop link connecting end user systems to the Internet. This success is apparent from the succession of new and improved versions of the 802.11 standard (WiFi) and the foreseen deployment of the 802.16 standard (WiMax). One of the notable developments in these systems is the introduction of mechanisms for store-and-forward operation. The present project has as objective the investigation of questions, relative to such systems, for which no complete answers exist in the areas of interaction between multiple access and routing. In addition to the issue dealt with by the classical routing problem in wired networks, namely choosing to which neighbor a newly received packet should be forwarded in order to attain a given optimization criterion, the issue of choice of transmitting power is critical for system performance, since it impacts the tradeoff between transmission range and interference. The project proposes to study both appropriate performance models and their application to system studies.
