The purpose of this paper is to introduce Naming application model for sensor networks. Currently, sensor networks comprised of sensor nodes have provided an application range which could not function before. However, unlike general network, current sensor networks are designed to cooperate with major wireless-capable sensor devices with limited resources. Thus, exporting/importing between individual sensor and current sensor networks is very inefficient and unstable. Attribute, schema and DIT(Directory Information Tree) must be designed for sensor network using SN LDAP application model in order to maintain transparency and provide constant service in a situation of data defect. With the system explained as above, Naming application model is made to manage SN Fuzzy Query. It shall be more efficient and stable structure as long as Naming application using a virtual equation in a certain environment with information collected from sensor node is provided. In this paper, I would like to introduce SN Fuzzy LDAP model for sensor network by quick Naming method. Also, naming application which is possible for fuzzy query in a certain environment based on the system will be proved.

Recently, SNS is widely used for various purposes such as fast decision making or effective business process in educational institutions or enterprise as well as general services for social networking. Unfortunately, all of existing general SNS platforms do not provide user groups with workspaces for sharing information in a hierarchical way, nor support the functionality of workspace backup for migrations. In this paper, we present a collaborative workspace environment named ElggSpace which extends the Elgg SNS platform with the C3ware collaborative middleware. With the help of C3ware, ElggSpace systematically supports collaborative workspaces that enable user groups to share massive resource in cloud storages. In addition, ElggSpace allows high-level access controls for resources management and the functionality of resource backup, supporting effective collaboration.
