When (mathcal {R}_{e}) (or (mathcal {R}_{c})) occurs, a relay service request is rejected, which can be viewed as equivalent to removing a request from the relay service request arrival process, without committing the energy or channel resource.
The hard challenge is to accurately identify and continuously learn the most important behaviours and accurately compute statistical prediction functions based on the observed demands and behaviours such as request arrival pattern, service time distributions, I/O system behaviours, user profile, and network usage.
The Breakers allows children 16 and under to stay in their parents' rooms at no charge; cots are free but must be requested before arrival.
For content request pattern, content requests are usually assumed to arrive in the network exogenously and the content request arrival process usually follows the Poisson process.
He estimated that 30percentt of the system's users request arrival messages, roughly the same percentage reported by United.
Simulation study shows that with the proposed approach, true video-on-demand in WiMax mesh networks can be achieved under high video request arrival rate.
By assuming file request arrival follows the Poisson process, we prove the effectiveness of the proposed schemes both analytically and experimentally.
Factors affecting service workload such as service time, transition probability, replication overhead for additional service etc. as well as the uncertainty in request arrival time are all taken into consideration in our model.
In this paper, based on the analytical model of ICN with receiver-driven transport protocol employing least-recently used (LRU) replacement policy, we derive expressions to compute the average content delivery time of the requests' arrival sequence of a single cache, and then we extend the expressions to a cascade of caches' scenario.
The results so far assume a Poisson request arrival process.
