Network latency causes a delay in transmitting a message from one location to another. This can be attributed to several other factors, such as network congestion, network traffic, and computer storage capacities. Of course, the distance between two locations is the main factor that contributes to the delay. Since transmission between two cities will not be a straight path, latency is subject to detour and can be a factor of any deviation between these cities. These factors, along with a loss of the data and energy aspects of the transmission, will be investigated as this paper attempts to summarize latency estimation using regression and numerical models. Path prediction can be done up to a number of transmission towers or satellites between two cities. Latency estimation to locate either the client, client server, or host will be analyzed using a liner regression model leading to the same numerical model. Reliability analysis stemming from latency will be done at the end of this article.
