The Internet of Things and Ubiquitous Intelligence （1）

The traditional Internet is oriented towards person-to-person connection, whereas the Internet of Things is oriented towards connection of inanimate objects. As such, the Internet of Things covers a larger range of connections and involves more semantics. Internet and telecom networks are focused on information transfer, while the Internet of Things is focused on information services. By combining sensor networks, the Internet, telecom networks, and cloud computing platforms, the Internet of Things can sense, recognize, affect, and control the physical world.

The Internet of Things – The future or the end of mechatronics

The advent and increasing implementation of user configured and user oriented systems structured around the use of cloud configured information and the Internet of Things is presenting a new range and class of challenges to the underlying concepts of integration and transfer of functionality around which mechatronics is structured. It is suggested that the ways in which system designers and educators in particular respond to and manage these changes and challenges is going to have a significant impact on the way in which both the Internet of Things and mechatronics develop over time. The paper places the relationship between the Internet of Things and mechatronics into perspective and considers the issues and challenges facing systems designers and implementers in relation to managing the dynamics of the changes required.

Is civic data governance the key to democratic smart cities? The role of the urban data trust in Sidewalk Toronto

Over the two and a half years of its existence, Alphabet/Sidewalk Labs’ smart city project in Toronto, Canada has been at the center of successive controversies relating to its proprietary approach to personal data. To address these concerns, Sidewalk Labs suggested putting the data collected in the smart city in a trust. As a “steward of urban data and the public interest,” the Urban Data Trust was expected to protect residents’ privacy, establish responsible data sharing standards, and provide individuals with a share in the profits derived from the data gathered about them. This article proposes technoscientific/platform capitalism theories as a theoretical framework in the research on data governance. I situate the Urban Data Trust within a series of policy responses to the problem of extractive data practices. I posit that the company’s data governance approach appeals to and sustains a political-economic regime governed by the logic of rent seeking, which aims to entrench the economic dominance of technological monopolies.

Evaluating Twitter Data to Discover User’s Perception About Social Internet of Things

Social Internet of Things (SIoT) is a young paradigm that integrates Internet of Things and Social Networks. Social Internet of Things is defined as a social network of intelligent objects. SIoT has led to autonomous decision making and communication between object peers. SIoT has created and opened many research avenues in the recent years and it is vital to understand the impact of SIoT in the real world. In this paper, we have mined twitter to evaluate the user awareness and impact of SIoT among the public. We use R for mining twitter and perform extensive sentiment analysis using supervised and semi supervised algorithms to evaluate the user’s perception about SIoT. Experimental results show that the proposed Fragment Vector model, a semi supervised classification algorithm is better when compared to supervised classification algorithms namely Improved Polarity Classifier (IPC) and SentiWordNet Classifier (SWNC). We also evaluate the combined performance of IPC and SWNC and propose a hybrid classifier (IPC?+?SWNC). Our analysis was challenged by limited number of tweets with respect to our study. Experimental results using R has produced evidences of its social influences.     

Achieving Max–Min lifetime and fairness with rate allocation for data aggregation in sensor networks

We consider the rate allocation problem for data aggregation in wireless sensor networks with two objectives: (1) maximizing the minimum (Max–Min) lifetime of an aggregation cluster and (2) achieving fairness among all data sources. The two objectives are generally correlated with each other and usually, they cannot be maximized simultaneously. We adopt a lexicographic method to solve this multi-objective programming problem. First, we recursively induce the Max–Min lifetime for the aggregation cluster. Under the given Max–Min lifetime, we then formulate the problem of maximizing fairness as a convex optimization problem, and derive the optimal rate allocation strategy by iterations. We also present low-complexity algorithms that an aggregation cluster can use to determine the Max–Min network lifetime and the fair rate allocation. Our simulation results validate our analytical results and illustrate the effectiveness of the approach.

Simulation and analysis of node throughput using smart antenna in wireless mesh networks

Smart antenna technology is introduced to wireless mesh networks. Smart antennas based wider-range access medium access control (MAC) protocol (SWAMP) is used as MAC protocol for IEEE 802.11 mesh networks in this study. The calculation method of node throughput in chain and arbitrary topology is proposed under nodes fairness guarantee. Network scale and interference among nodes are key factors that influence node throughput. Node distribution pattern near the gateway also affects the node throughput. Experiment based on network simulator-2 (NS-2) simulation platform compares node throughput between smart antenna scenario and omni-antenna scenario. As smart antenna technology reduces the bottle collision domain, node throughput increases observably.     

Understanding the impacts of Internet use on senior Citizens’ social participation in China: Evidence from longitudinal panel data

Scholars have appealed to build a digitally inclusive society to include senior citizens. However, conclusions on the impacts of Internet use on senior citizens’ social participation are divided. In order to address the above issue, this study addresses two questions: 1) how Internet use is related to senior citizens’ social participation; and 2) what the specific impacts of Internet use are on different subgroups’ social participation. We aim to understand the specific impacts of Internet use on senior citizens’ social participation meanwhile explore the reasons causing the abovementioned inconsistence in prior studies. We ran different panel regression models to address these questions based on a dataset drawn from the China Health and Retirement Longitudinal Study. Our empirical results indicate that seniors who are Internet users have higher social participation than those who do not use the Internet even after controlling out other influencing factors; however, frequent Internet use leads to less social participation among senior citizens. For senior citizens with higher cognitive functioning, both using Internet or not and the frequency of Internet use lead to more social participation. Both using Internet or not and the frequency of Internet use cause senior citizens with pensions to engage in fewer social activities. For female senior citizens, frequent Internet use leads to lower social participation. These findings suggest that government and communities should improve digital infrastructures and offer senior citizens more opportunities to access the Internet; meanwhile, local communities, social workers, and family members should direct senior citizens to use the Internet in a reasonable manner.     

AEETC—adaptive energy-efficient timing control in wireless networks with network coding

Energy is a scarce resource in wireless networks. Network coding has been proposed recently as a means to reduce the number of transmissions and energy consumption. In this paper, we introduce timing control into network coding to further enhance its performance. It is found that when bandwidth is sufficient, the extra delay introduced by waiting for additional data to perform network coding will increase the number of codings without affecting system throughput. Both delay and throughput suffers when bandwidth is insufficient. An adaptive energy-efficient timing control algorithm called AEETC is proposed which can automatically adjust local node’s transmission behavior on the basis of the network traffic conditions. Simulation results demonstrate that AEETC increases network coding by 7% to 60% for light network load and is able to provide good performance in terms of delay, throughput and the number of successful codings.
