we concern about the distribution of the terminal time of semi-dynamic system,it can be see as generalization of that of stochastic process.

To increase average throughput and decrease end-to-end delay of underwater acoustic networks,the original MACAW protocol is improved according to the low quality and high delay characteristics of underwater acoustic channel.

The end-to-end delay bound of packets was studied.

Then,this conclusion was generalized to more general cases,and end-to-end delay of packets in the guaranteed rate node-formed network is analyzed according to this conclusion,and a tight delay bound is got.

Simulation shows that the advanced version can observably reduce the end-to-end delay without too much increased overhead compared to AODV.

The maximum end-to-end delay bound, the maximum backlog bound and the effective bandwidth of IntServ guaranteed service are derived.

This paper presents network model and NCS model,analyzes the characteristics,the components and the bottleneck of the end-to-end delay based on the OPNET simulation results,and studies the relationship between the data packet size and delay.

To estimate performance of ESSDRR in end-to-end delay and short-term throughput property,extensive simulation experiments have been done using NS2 in the same condition.

In order to reduce the measurement traffic in network topology inference algorithms based on end to end delay,a cluster measurement method and two step topology inference algorithm are proposed.

This paper implemented end to end delay meas.
