Network Coordinate System (NCS) has drawn much attention over the past years thanks to the increasing number of large-scale distributed systems that require the distance prediction service for each pair of network hosts. The existing schemes suffer seriously from either low prediction precision or unsatisfactory convergence speed. In this paper, we present a novel distributed network coordinate system...
Device-to-device (D2D) communication is one of the key technologies in Long Term Evolution — Advanced (LTE-A) for improving network capacity and resource utilization. D2D communication can not only effectively reduce traffic loads to the core network but also reduce power consumption of user equipments (UEs), thus making it a desirable candidate for machine-to-machine communication in cellular networks...
The environmental science communities are actively engaged in developing the next generation of large-scale sensor based field observing systems. The challenges that these systems face are listed as below: complexity of sensor data stream processing and effects of Web-based real-time data display. In this paper, we utilized the RBNB DataTurbine, an open-source streaming data middleware to improve...
In this paper, we proposed a semi-distributed transportation and management network for field ecological data collection. We developed the semi distributed transportation network to transmit the real-time video data and real-time flux data in the ChinaFlux project, and utilized the SRB technique to manage the distributed ecological data among different observation sites in the ChinaFlux project. We...
In the field ecological data collection process, lots of heterogeneous data are generated by equipments which are composed of hundreds to thousands of sensors and cameras and it is a big challenge to collect and manage these data. In this paper, we proposed a five layer framework named FEDC which can be used in the field ecological data collection and management. FEDC is a hybrid-distributed framework...
In order to support process construction in wireless migrating workflow system, this paper presents an approach based on task components for resource-limited executing environment. First, we propose a business process construction model based on the idea that the process logic is separated from the process instances, and then abstract the process generation as a resource-constrained combinatorial...
