Nowadays most medium access protocols designed for wireless ad hoc networks are based on collision avoidance strategies like the CSMA/CA based IEEE 802.11 protocol. But these types of protocols are not designed for multi-hop scenarios -- the efficiency of the channel utilization is too low which results in, among others, large packet delays. One popular approach to increase the channel utilization is to reserve time slots along a transmission path, thus having a scheduled access. However, a major problem is interference from nearby nodes, although these nodes are not on the same route. This might lead to destruction of ongoing data receptions. In this paper we suggest a new reservation protocol, called JamTDMA. It offers protection against this effect by advertising the reservations in a larger neighborhood. We will show that this protocol allows to improve the rate of successfully received packets while assuring an upper bound for the end-to-end delay.
