Clustering is an effective approach to hierarchically organizing network topology and to prolong the lifetime of a wireless sensor network. Current clustering protocols usually utilize two techniques: selecting cluster heads with more residual energy and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster. Most of the researches in this field has focused...
Although numerous routing protocols have been designed for wireless sensor networks, not all are suitable for wireless sensor networks in home automation (WSNHA). In this paper, we evaluate some popular wireless sensor network routing protocols for their suitability to WSNHA. We also propose a greedy-algorithm heuristic routing (GAHR) protocol and an A* algorithm for route finding. We compared the...
In intelligent inhabited environments (IIEs), the different user's preferences and needs are different, and the same user's preferences will change over time, which desire that the intelligent agents have evolvement function. In this paper, we propose a new fuzzy control system that is embedded in the intelligent agent which is a function agent in Multi-Agent System (MAS) based on ZigBee wireless...
The clustering algorithms for wireless sensor networks might differ depending on the application and network architecture. Not all clustering algorithms are suitable for wireless indoor monitoring system. In this article, we summarize the features of wireless indoor monitoring system, analyze the clustering algorithms for wireless sensor networks, and provide a clustering algorithm based on K-means...
This article puts forward a method to access the data and analyzed results from the monitoring system of environment based on WSN with the B/S mode. It resolves the problem of low speed of page refresh with Ajax. The experiment shows that the partial refresh feature of Ajax can make it possible for the users to get access to the data and analyzed results easily through the browser, and experience...
To deal with the problem of mine safety monitoring, an improved TinyOS Beaconing-based WSN routing protocol is presented in this paper. Comparing to TinyOS Beaconing protocol, this improved protocol can not only aware Energy and repair route automatically, but also can inhibit the number of child nodes and that of system levels. The prominent characteristics are small routing table, long life, high...
ZigBee is a standard wireless network protocol for low rate control network with the advantages of low complex, low cost, low consumption and high safety. A Multi- Agent System (MAS) architecture developed for an intelligent inhabited environment (HE) based on ZigBee wireless sensor network is introduced. The MAS has the features like distributed control, cooperation, and coordination that make it...
In this paper we present the simulation-based performance evaluation and tuning of data dissemination in wireless sensor networks. The simulation uses directed diffusion protocol for query and data dissemination. The implementation is done in Java using eclipse. The simulation includes four phases: interest propagation, gradient establishment, data propagation, and reinforcement of path establishment...
