Expected Data Rate: An Accurate High-Throughput Path Metric for Multi-Hop Wireless Routing

Overview This paper presents a new metric, Expected Data Rate (EDR), for accurately finding high-throughput paths in multihop ad hoc wireless networks. The metric is based upon a new model for transmission interference which is a critical factor in determining path throughput. This paper constructs a realistic and practical transmission interference model by determining transmission contention degree of each link as a function of the wireless link loss; quantifying the impact of the wireless link loss on medium access bakeoffs; and considering possible concurrent transmissions when two links do not interfere with each other. The transmission interference model also takes the non-optimality of IEEE 802.11 medium access scheduling into account.

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
