With the advancement in energy harvesting in terms of wireless charging techniques, it provides a novel way to solve traditional energy constraint problems in Wireless Sensor Networks (WSNs). Renewable energy such as solar, wind, and geo-thermal energy is converted to energy-storage and further use via harvest-then-transmit strategy. This article introduces a two-layer sleep scheduling system in energy-harvesting...
With the development of wireless sensor networks, privacy-preserving has become a very important problem in numerous wireless sensor networks (WSN) applications. This paper presents a novel energy-efficient secure data aggregation scheme cluster-based private data aggregation (CSDA) based on cluster privacy-preserving. It has good flexibility and practical applicability using the slice-assemble technology...
Group connectivity is one of the major research challenges in large-scale industrial wireless sensor networks (IWSNs). Critical nodes (CNs) are mainly responsible to maintain group-connectivity. This article focuses on prioritize these CNs to sleep more than other nodes in order to save their energy resulting prolong global connectivity in group-based IWSNs.
With the advancement in energy harvesting, wireless powered communication networks overcome the problem of replacing fixed energy sources, e.g., batteries in difficult access areas of industrial networks. However, the harvested energy is not always enough to support reliable and low end-to-end data transmission in industrial wireless sensor networks (IWSNs). This poster introduces an energy utilization-concerned...
Wireless Powered Communication Networks (WPCN) is one of the promising approaches to extend the lifetime of the energy-constrained wireless networks such as Wireless Sensor Networks (WSNs). With the advancement in energy harvesting in terms of Wireless Energy Transmission (WET), WPCN overcomes the problem of replacing fixed energy sources such as batteries in difficult access areas of industrial networks...
Sharing the infrastructure of wireless sensor networks (WSNs) for achieving concurrent requests becomes a trend nowadays, where a relatively complex request should be satisfied through aggregating complementary functionalities provided by contiguous sensor nodes contained in a certain network region. To address this challenge, this paper proposes a multi-requests cooperative-integrating mechanism...
This paper develops an analytic model to study sensor sleep mechanism. Different from previous works, theoretical analysis herein demonstrates that sleep period can be treated as arrival of group packet rather than server vacation, so that the sensor node can be simply modeled as a continuous service system without sleep. Explicit forms of duty cycle, and means of total queuing delay and queue length...
With wireless communication and the speedy development of micro-electro-mechanical system (MEMS), the wireless sensor network (WSN) has aroused enthusiasm in the world. The research of intelligent transportation system base on WSN is a hotspot to solve the traffic problems in recent years. This paper first introduces intelligent transportation system base on RFID and WSN, then discusses the hardware...
Wireless sensor networks have been extensively adopted in numerous application scenarios. However, increasing environmental constraints and performance requirements has spurred the development of tools to expedite deployment and minimize human intervention. This study extends previous work by the authors in network development and aims at the performance evaluation of applications operating in to-be-deployed...
Wireless sensor networks (WSNs) have been extensively researched recently. This paper makes two contributions to this field. First, we promote a new concept of long-thin (LT) topology for WSNs, where a network may have a number of linear paths of nodes as backbones connecting to each other. These backbones are to extend the network to the intended coverage areas. At the first glance, a LT WSN only...
Although we can use telecomm technologies such as MMS to access various services, right now we do not have a good method to access several services at a time. In this paper, we propose a service-based P2P mobile sensor network (SPMSN) architecture. It allows users to adopt an integrated method to access various services even these services are not in the same physical network. An efficient communication...
