Delay control in wireless ad-hoc networks is difficult to be achieved due to factors including random nature of the medium access control and the difficulty in enforcing admission control in non-centralized networks. Since end-to-end delay is largely affected by queuing delay, it is conceivable that load control schemes could be useful not only in avoiding congestion but also in controlling per-hop delay. In previous work, we presented a per link load control scheme which aims at regulating load condition network-wide, using rate-based signaling, in order to avoid congestion and improve channel utilization. In this paper, we 1) apply the scheme to the problem of delay control, 2) present a version which aims at reducing signaling rate, and 3) evaluate the impact of control interval on the performance of the scheme. As compared to the case that there is no load control scheme in place, it is shown that a maximum reduction of about 40% in the end-to-end delay and an improvement in delivery ratio from 8 to 47 times the case of no load control can be achieved. It is also shown that by a proper modification of the scheme, a reduction between 8% and 56% in signaling rate can be achieved without any noticeable degradation in end-to-end delay and delivery ratio performance. |
