Serie Re5ehrch Rieriorrhdr a Simple Performability Estimate for Jackson Networks with an Unreliable Output Channel

This paper provides a simple performance estimate with an explicit error bound for open Jackson networks with departure blocking such as due to an output channel with breakdowns.

Analysis of Jackson networks with infinite supply and unreliable nodes

Jackson networks are versatile models for analyzing complex networks. In this paper we study generalized Jackson networks with single-server stations, where nodes may have an infinite supply of work. We allow simultaneous breakdown of servers and consider group repair strategies. We establish the existence of a steadystate distribution of the queue-length vector at stable nodes for different ty...

Local Stabilization of Non-Ergodic Jackson Networks with Unreliable Nodes

This thesis contributes to a better understanding of the behavior of queueing networksthat cannot approach a classical equilibrium state.We consider Jackson networks with unreliable nodes which randomly break down andare under repair for a random time. Our networks are described by Markov processesthe states of which incorporate the availability status and the queue-lengths vect...

Simple Channel Assignment Strategies for Multiple Channel Ad Hoc Networks

Previous studies by the author examined the feasibility of applying channel changing strategies in ad hoc networks, with varying degrees of mobility, as a means to improve total system throughput and individual flow throughput, as well as to reduce network congestion. These studies presented several heuristic methods that allowed a greatly improved performance to be delivered per network flow. ...
