Abstract :
An on-demand and dynamic slot assignment (ODSA) protocol for ad hoc networks is proposed. The protocol assigns slots for nodes basing on information in their two-hop neighborhood, which can be collected by listening before slot assignment. In ODSA, a slot is divided into several mini-slots, and the reservation procedure is realized in the selected idle slot by message exchanging. ODSA can adapt to variations of application and network topology. Furthermore, it can ensure the time delays of nodes owning slots. ODSA has been studied in different network situations, and the results show that ODSA has smaller average access delay and higher channel utilization compared with FPRP
