—This paper presents a theoretical estimation for idle channel time in a multi-hop environment. Idle channel time is the time proportion of a node during which the channel state is idle. Thus, it can be used to evaluate the available bandwidth. Major related work considers a cross-layer model, where the idle channel time measure is available at the MAC(More)
—This paper presents an admission control algorithm based on dynamic constraints for multi-hop networks. Assuming each node knows the topology and flow reservations within its radio range, local constraints on flow rates can be computed. As long as these constraints are satisfied, flows are accepted. Since computing optimal constraints is not practical,(More)
Ce rapport technique présente un algorithme permettant d'augmenter les débits atteignables dans un réseau multi-sauts sans-fil en définissant les puis-sances d'´ emission les plus adaptéesà un certain trafic. ` A la différence de la majorité des travaux existants, nous ne considérons pas que la réduction des puissances d'´ emission implique réduction des(More)
