Fuel economy is closely related to driving style, traffic situation, and urban geomorphic environment. In this study, the authors propose to compare fuel consumption based on normalised driving behaviour. A personalised driver model is established for each driver by using the locally designed neural network and the real-world vehicle test data. Driving behaviour is normalised by employing the personalised...
Sleep Scheduling is one of the most important challenges for energy conservation in Wireless Sensor Networks (WSNs). Connected Dominating Set (CDS) based virtual backbone is often employed in WSNs. Compared with the ordinary CDS, the R-hop Connected Dominating Set (R-CDS) with smaller size is more suitable for build a virtual backbone for energy conservation. In this paper, a R-hop connected dominating...
Hybrid Wireless Mesh Networks (HWMNs) were proposed to address the challenges in wireless communications to support mobile applications across different domains. Due to the multi-hop and decentralized network architecture HWMNs are naturally susceptible to various security threats, especially internal attacks. Therefore HWMNs must be able to detect anomalies, provide secure routing and protect user...
The Wireless Sensor Converge-cast Networks (WSCNs) are widely applied in many fields such as medical applications and environmental monitoring. The monitoring data are collected from the sensors and gathering toward the sink node. A coding aware routing scheme based on Connected Dominating Set is provided. Based on CDS, a coding condition, named Improved Coding Conditions (ICC), is defined with an...
The increasing requirements on cloud computing entail building up large numbers of large-scale data centers which require a surprising amount of energy. With the gradual depletion and price escalation of traditional energy, operating data center in an energy efficient way is an emerging urgent problem. However, most existing researches of resource allocation in datacenter did not take into full consideration...
Cloud services decouple cloud applications from IT infrastructure in cloud environment. On demand resources provisioning pattern makes high efficient resource utility and application dynamic scaling possible. Hence Cloud data center could provide infrastructure capabilities in a more energy efficient way. However, there exists a tradeoff between energy efficiency and application service level objectives...
As a pillar industry of the national economy, the logistics shared a great responsibility in low carbon economy. This paper which based on the combination of qualitative analysis and quantitative model indicated that the logistics industry could promote the development of low carbon economy by integrating resources and optimizing configuration. But the effection is inflexible at present, the main...
This paper investigates how the small world concept can be applied in the context of wireless sensor networks. We investigate the use of wired short cuts in clustered wireless sensor networks. Before adding wires, we divide the network into clusters with high clustering coefficient. Then add wires acting as shortcuts to bring down the hop count in order to construct a small world. We have developed...
Topology control is an effective measure at network layer to implement power control for energy-saving, which is a critical issue in ad-hoc wireless networks. Topology control also affects other significant performances of network, such as packet delivery radio, end-to-end delay, and network capacity etc. Various techniques and algorithms have been proposed to achieve the optimal topology which can...
