Understanding the impact of circuit-level inaccuracy on sensor network performance

Energy efficiency is of paramount importance in designing low-power wireless sensor nodes. Approximate computing is a new circuit-level technique for reducing power consumption. However, the gain in power by applying this technique is achieved at the cost of computational errors. The impact of such inaccuracies in the circuit level of a radio...

SON for LTE-WLAN access network selection: Design and performance

Mobile network operators (MNOs) are deploying carrier-grade Wireless Local Area Network (WLAN) as an important complementary system to cellular networks. Access network selection (ANS) between cellular and WLAN is an essential component to improve network performance and user quality-of-service (QoS) via controlled loading of these systems. In...

The effect of inaccurate traffic data for ramp metering: Comparing loop detectors and cameras using information utility

This paper introduces a topic which is of growing interest in the traffic control and management community, namely the relation between traffic data quality and the efficiency of traffic management. After some explanatory background and state of the art, it will become clear that no standard approach is available for traffic engineers to...

The Effects of Boundary Spanners on Trust and Performance of Urban Governance Networks

Previous research has extensively analyzed the role, and indicated the importance, of network management for the functioning and performance of public or governance networks. In this article, we focus on the influence of boundary spanning actors in such networks – an aspect less examined in the governance network literature. Boundary spanners...

Harnessing Complexity within Governance Networks in a Legitimate Way: The Effects of Connective Management and Throughput Legitimacy on Network Performances

The relationship between network management, network performances, and democratic legitimacy is a highly debated issue. In this article, we explore this relationship theoretically. Building on the literature, we expect to find that democratic throughput legitimacy has a partly mediating role in the relationship between connective network...

Performance evaluation and traffic modeling

Mobile and wireless communication systems are becoming more and more complex, making understanding the interaction of different technologies on different layers a very difficult task. The introduction of sophisticated techniques on the physical layer that react to changes of the wireless channel on small timescales requires new paradigms for...

Wireless network simulation - Your window on future network performance

The paper describes three relevant perspectives on current wireless simulation practices. In order to obtain the key challenges for future network simulations, the characteristics of "beyond 3G" networks are described, including their impact on simulation. © Springer 2005.
