The transmission of massive highly related data could generally exist in gathering scenario of sensor networks and lead to the depletion of valuable energy resource. According to the above energy waste problem, an effective filtering mechanism is proposed in the paper to enhance the energy-efficiency of data-gathering. Many current researches adopt clustering method and aggregation technology to lower...
The coal mine laneway is a kind of limited and changeable space with bend and embranchment in a longitudinal way. Its complicate environmental condition influences the connectivity, coverage, the packet loss rate and energy consumption of the wireless sensor networks. To construct the real system of wireless sensor networks for mine working environment, this paper proposes a clustering-based chain-type...
Based on the analysis of accomplishments and trends of modern technologies (such as the computer, wireless communication, creature science, nanotechnology, medical science, et al.), this paper makes a prediction of the future network, and proposes a new concept - the human body network (HBN), which is formed by people around the world whom are equipped with special micro chip in their body. The HBN...
In this paper, we present an extensible, component-oriented, concurrent discrete-event driven wireless sensor network simulation platform: H-Sim. The components of the H-Sim system have high reusability and low coupling, it can solve the problems of having high coupling between modules and difficult to debug and use which exist in other simulation systems like NS-2. H-Sim can simulate the sensor nodes...
With the developments of related techniques in telecommunication and computer sciences, wireless sensor networks have been used more and more widely. While sensor nodes in wireless sensor networks have very limited memory spaces and power. In this paper, we propose a new method to preprocess the query predicates. The size of the relational table can be further reduced using the aggregated query predicates...
Some applications need to collect information from several different sensor networks to provide comprehensive services. In order to simplify the complexity of dealing with heterogeneous sensor networks, a uniform interface should be provided for users. This paper describes a novel approach to integrate these different sensor networks into one virtual sensor network. Users can easily query data through...
