Importance Sampling Estimation of Joint Default Probability under Structural-Form Models with Stochastic Correlation

This paper aims to estimate the joint default probability under the structuralform model with a random environment; namely stochastic correlation. By means of a singular perturbation method, we obtain an asymptotic expansion of a two-name joint default probability under a fast mean-reverting stochastic correlation model. The leading order term in the expansion is a joint default probability wit...

On improved estimation for importance sampling

The standard estimator used in conjunction with importance sampling in Monte Carlo integration is unbiased but inefficient. An alternative estimator is discussed, based on the idea of a difference estimator, which is asymptotically optimal. The improved estimator uses the importance weight as a control variate, as previously studied by Hesterberg (Ph.D. Dissertation, Stanford University (1988);...

Call admission method for call dropping probability guarantee in LEO satellite networks

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...

Efficient Delay Probability Scheme for Handover in Wireless Networks

In this paper a efficient delay probability scheme for handover in wireless network is proposed. In this paper analysis are obtained on the strength based Priority handover scheme. This scheme is proposed for vertical handover in various wireless systems. Since handover means transferring an on going cell or data session one cell to another and there are some imitation like data rate, mobility,...
