I am willing to know the time delay expected in communication links as to have it for Automatic Generation Control. If possible I will need papers that support that.
The time delays and other channel characteristics depend on the environment of the considered system.So, for each system , there are specific channel models that determine all channel characteristics.
There are so many types of delay in the End Terminal Communication Devices,in the Channels of Communication Networks,Relays ,Types of Communication etc. estimation of which and the Method to have Adaptive Communication with Tolerance for Delay can be found in the Following References. Some other Information on the Subject are are Patented.
1. Latency (engineering)
Latency is a time interval between the stimulation and response, or, from a more general point of view, as a time delay between the cause and the effect of some physical change in the system being observed.
In communications, the lower limit of latency is determined by the medium being used for communications. In reliable two-way communication systems, latency limits the maximum rate that information can be transmitted, as there is often a limit on the amount of information that is "in-flight" at any one moment. In the field of human–machine interaction, perceptible latency has a strong effect on user satisfaction and usability.

2. Delay-tolerant Adaptive Real-time Communication: A Case Study for Voice
Nagasai Panchakarla and Jörg Ott
ABSTRACT
Delay-tolerant networking allows dealing with temporary disconnections and non-available end-to-end paths. While many DTN system designs focus on asynchronous applications (such as messaging or content sharing), DTN communication may also be a suitable fallback for adaptive real-time applications if end-to-end communication fails. In this paper, we explore this idea to enhance
the adaptivity of real-time voice for which we design a system that switches between RTP/UDP-based and RTP/DTN-based voice as a function of the observed RTT and loss rate.
3. Inference of Link Delay in Communication Networks
Ye Xia, David Tse
ABSTRACT This paper studies the feasibility and algorithms for inferring the delay at each link in a communication network based on a large number of end-to-end measurements. The restriction is that we are not allowed to measure directly on each link and can only observe the route delays. It is assumed that we have considerable flexibility in choosing which routes to measure. We investigate two different cases: 1) each link delay is a constant and 2) each link delay is modeled as a random variable from a family of distributions with unknown parameters. We will answer whether such indirect inference is possible at all, and when possible, how it can be carried out. The emphasis is on developing the maximum-likelihood estimators for scenario 2) when the link delays are modeled by exponential random variables or mixtures of exponentials. We have derived solutions based on the EM algorithm and demonstrated that, even though they do not necessarily reflect the true model parameters, they do seem to maximize the likelihood in most cases and that the resulting probability density functions match the true functions on regions where the probability mass concentrates
4. Relay Communication with Delay Diversity forFuture Communication Systems
S. Ben Slimane and Afif Osseiran
Abstract
—In this paper we consider relay communication as a way of increasing the diversity gain in fading wireless environments. The idea is to combine relay communication with delay diversity where each relay introduces a certain time delay tothe signal before forwarding. The result is an increased frequency selectivity in the relay channel which can be exploited at there ceiver. The obtained results show that, for single carrier signals with frequency domain equalization, considerable performance gain is obtained.
