Phase change memory (PCM) is one of the most promising candidates to replace DRAM as main memory in deep submicron regime. Regardless of single-level or multiple-level cells, the programming costs to each state exhibit significant asymmetries in latency, energy and endurance. In this paper, we exploit the potential of reducing programming costs in terms of latency, energy, and endurance for PCM through...
Probability of successful delivery under deadline constraints is one of the most important performance measures in a wireless real-time multihop control and sensor network. In this paper we approach the problem of determining the probability of successful packet delivery by calculating the per-link outage probability for different fading channel models. We provide easily computable results for the...
The dynamic nature of mobile ad hoc networks poses fundamental challenges to the design of service composition schemes that can satisfy the end-to-end quality of service requirements and minimize the effect of service disruptions caused by dynamic link and node failures. Although existing research on mobile ad hoc networks has focused on improving reliability, little existing work has considered service...
Recent advances in wireless sensor technology facilitate the development of remote healthcare systems, which can significantly reduce the healthcare cost. Despite the initial promising results, there remain many obstacles to apply this technology to the practical medical care context. One of the critical issues is to assure the timely and robust delivery of the life-critical medical data in the resource-constrained...
The dynamic nature of mobile ad hoc networks poses fundamental challenges to the design of service composition schemes that can minimize the effect of service disruptions. Although improving reliability has been a topic of extensive research in mobile ad hoc networks, little work has considered service deliveries spanning multiple components. Moreover, service composition strategies proposed for wireline...
