We consider policies for deciding which cells will be lost or dropped when losses occur at a nite buuer ATM node. The performance criteria of interest are the delay of transmitted (non-lost) cells, the jitter (or variability in the delay of transmitted cells), and the burstiness of lost cells. We analyze the performance tradeoos for various cell dropping policies. We show the usual the rear dro...

This paper proposes a new call admission control scheme considering the call dropping probability of ongoing calls in LEO satellite networks. Quality of service (QoS) provisioning of low handover failure probability is used in the proposed call admission control (CAC) scheme to guarantee predefined acceptable call dropping probability for each call. To ensure the call dropping probability the h...

The objective of this paper is to determine the minimum system dropping rate (or, equivalently , dropping probability) induced by TDMA schemes supporting time-constrained applications with common maximum cell delay tolerance. Expressions are derived for the induced system dropping rate for various TDMA schemes with diierent overhead and the maximum number of users than can be admitted in the ne...

For state estimation over a communication network, efficiency and reliability of the network are critical issues. The presence of packet dropping and communication delay can greatly impair our ability to measure and predict states. In this paper, multiple description (MD) codes, a type of network source codes, are used to compensate for this effect on Kalman filtering. We consider two packet dr...

This paper studies pricing strategies for networks with stochastic capacity variation. Call-level simulation is used to compare the profit generated with four different pricing models, and with different policies for the management of call dropping episodes in the network. Both user-oriented and network-oriented performance metrics are considered. The simulation results show that the choice of ...
