System and method for interactive electronic media extraction for web page generation

A system and method for parsing an electronic media database structure to produce tagged data that preserves the content, links, and electronic media structure. In particular, HyperText Markup Language (HTML) data is generated as an Interactive Electronic Technical Manual (IETM) (home page) linked into a relative structure of Web pages to support IETM deployment. An extraction process assesses the functionality associated with each node designated for presentation and builds a virtual Web, based on attributes stored in the IETM database. A series of Web pages with links that hierarchically presents IETM data at run time is produced. The method supports a data warehousing strategy that converts any data type eligible within the relational database. This expands support across multiple types of technical and engineering data. The preferred implementation utilizes a relative addressed pure HTML solution viewable in standard Web browsers. This open system implementation is cross platform and infrastructure independent, requiring no special server software. Retaining the hierarchical structure dictated by the relational database in HTML output enhances the supportability and maintainability of the Web implementation. Updates to this Web implementation can be incrementally applied within the hierarchy (small sections of data) or the entire logical sections of Web data.

The routing method is composed of initialization, cluster building, adjacent clusters routing and routing maintenance, wherein, an initialization process of the protocol makes a Sink node obtain a topology and network average energy of the sensor network, and each node obtains hop counts from the node to the Sink node; in the stage of the cluster building, a repeated division method is used to divide sensor network clusters, the divided clusters are even, and a leader cluster node is undertaken by nodes with higher residual energy; the adjacent clusters routing uses an ant colony algorithm to determine the probability of using a link to send information according to the link pheromone concentration, and the link pheromone concentration is increased with the information transmission on the link and is reduced with the time going; and the routing maintenance stage is responsible for updating link pheromone concentration, and makes the nodes inside the cluster with higher residual energy undertake the leader cluster in turn. The routing method can reduce the consumption of the network total energy, can balance the consumption of the node energy and can prolong the network life cycle.

Wireless sensor network multi-source data fusion method based on queries

The invention relates to a wireless sensor network multi-source data fusion method based on queries. The wireless sensor network multi-source data fusion method based on the queries comprises clustering, interest spreading and data transmission. In the clustering process, node residual energy to cluster, density of a node placed area and the distance from cluster heads to a base station are utilized. In the interest spreading process, a sink node firstly spread interest news to all cluster heads which then determine whether interest is spread inside clusters according to actual conditions. In the data transmission process, a neighbor node large in priority is chosen as a next jumping node. A priority function enables query data to be transmitted to the sink node along the route which is small in energy consumption, large in residual energy and short in distance according to introducing of neighbor node positions, the fact that whether introduced nodes are source nodes or the cluster heads, residual energy, communication cost of two nodes and the like, and data fusion is performed on the data intersecting position. The wireless sensor network multi-source data fusion method based on the queries can effectively balance node energy consumption in networks, improve energy using efficiency and prolong a network life cycle.
