Recently, a two-phase handoff protocol has been proposed to support inter-switch handoff in wireless ATM networks. It employs path extension for each inter-switch handoff, followed by path optimization if necessary. In this paper, we propose a number of path optimization initiation schemes to facilitate the two-phase handoff protocol. The design objective(More)
In this paper, we study the connection rerouting problem due to inter-switch handoffs. The design objective is to guarantee the bandwidth and delay of a connection during its connection lifetime. We propose to use path extension for each inter-switch handoff, and invoke path optimization whenever one of the potential handoff paths exceed the delay(More)
Path optimization is required for those connection rerouting schemes where the path after an inter-switch handoff is not optimal. In this paper, we evaluate the performance of three path optimization schemes (namely: exponential, periodic, and Bernoulli) for the two-phase inter-switch handoff protocol. Using analytical modeling and simulation, we determine(More)
In order for simulation based training to help prepare soldiers for modern asymmetric tactics, opponent models of behavior must become more dynamic and challenge trainees with adaptive threats consistent with those encountered increasingly in the real world. In this presentation we describe an adaptive behavior modeling framework designed to represent(More)
