Integrated management model (SNMP/SMI) for lubiquitous egacy remote communication network or service make possible combination of various architecture. However, legacy management system cannot be applied some problems such as inefficient, complexly, implement and large network by reason of integration of voice and data, wired and wireless, and service area between service provider. For improve this, supplied JMX(Java Management eXtensions) on network management technology from SUN. JMX is integrated architecture for existing network management and monitoring. In this paper, we design and implement for integrated network management through multi-protocol agent using JMX.

Group communications are becoming popular in Internet applications such as video conferences, on-line chatting programs, games, and gambling. Secure and efficient group communication is needed for message integration, confidentiality, and system usability. However, the conventional group key agreement protocols are too much focused on minimizing the computational overhead by concentrating on generating the common group key efficiently for secure communication. As a result, the common group key is generated efficiently but a failure in authentication allows adversaries to obtain valuable information during the group communication. After achieving the secure group communication, the secure group communication should generate the group key efficiently and distribute it to group members securely, so the balance of security and system usage must be considered at the same time. Therefore, this research proposes the software architecture model of a secure and efficient group communication that will be imbedded into networking applications.

In this paper, we introduce the design and implementation of Information exchange technique among power system facilities and/or their monitoring systems based on Universal Description, Discovery and Integration Service and Simple Object Access Protocol. The rapid progresses in high speed network, 4G web language S/W and embedded H/W enabled faster and easier communications among electric power systems monitoring facilities. However, each facility or system has its own specific protocol like RS-232 and RS-486, which somewhat limits the capability of flexible information exchange among thor In this paper, we try to demonstrate the potential of utilizing the SOAP and UDDI services in exchanging the metadata and possibly high abstraction level informations among electric power facilities and/or their monitoring systems.

WSNs is evolving different kinds of networks depending on different circumstances, among those we have HWSNs (Hybrid Wireless Sensor Networks) which invokes sensor nodes mobility. In hybrid wireless sensor networks (HWSNs), reducing energy consumption of resource constrained and adaptability to the sensors nodes motion are the crucial problems; to overcome this we need a scalable MAC protocol. Many MAC protocols have been proposed by different researchers, but in this paper we propose LMAC because it outperforms S-MAC, T-MAC and D-MAC protocols comparing to its improvement of energy efficiency and mobile adaptability.

A Wireless Body Area Network (WBAN) allows the seamless integration of miniaturized sensor nodes in or around a human body, which may cause damage to the surrounding body issue due to high temperature. Although various temperature aware routing protocols have been proposed to prevent temperature rise of sensor nodes, most of them accommodate single traffic transmission with no mobility support. We propose a Forwarder based Temperature Aware Routing Protocol (FTAR) that supports multiple traffic transmission for normal and critical data. Normal data is forwarded directly to the sink through forwarding nodes which are selected among mobile nodes attached to the arms and legs, while critical data is forwarded to the sink through static nodes attached to fixed body parts with no mobility. We conduct extensive simulations of FTAR, and conclude that FTAR has good performance in terms of hot spot generation ratio, hot spot duration time, and packet delivery ratio.

As the importance and the need for network security is increased, many organization uses the various security systems. They enable to construct the consistent integrated security environment by sharing the vulnerable information among firewall, intrusion detection system, and vulnerable scanner. We construct the integrated security simulation environment that can be used by some security system model. In this paper, we have designed and constructed the general simulation environment of network security model composed of multiple IDSs agent and a firewall agent which coordinate by CNP (Contract Net Protocol). The CNP, the methodology for efficient integration of computer systems on heterogeneous environment such as distributed systems, is essentially a collection of agents, which cooperate to resolve a problem. We compare the selection algorithm in the CPN with the Fuzzy Controller for the effective method to select the agents.

Current Internet services do not consider the service level interoperability because each service is developed with its own interface, which is not compatible with other services. This means that characteristics of Internet services are autonomous and heterogeneous. Moreover each service has its own access method, data representation, and data structure. This will make it difficult for NGN services to be converged. For the convergence scenarios of NGN services, interoperability among different applications shall be supported in service layers in various network environments. In order to realize this, integration function in applications is necessary. And, it is also required that NGN services shall consider to adopt the conventional E-business framework such as ebXML in order to create value added services.

Using integrated construction project data is necessary for efficient management of construction projects. Recently IFC(Industry Foundation Classes) are proposed as integration method based on interoperability and there have been several cases of system integration based on IFC. The concept of interoperability proposes the construction object as data sharing protocol between systems for system integration and independence of each system. This study proposes system development strategy by phases considering work scope and procedure of processes based on the concept of interoperability. This is proposed to overcome tendency of developing system which doesn't support real work processes as result of inclining to the format of IFC instead of properly using IFC's interoperability concept to real work scope and procedure.

Automation of production in modern manufacturing is based on the integration of the various stage of production process by means of processing system. Information processing and network interface are of fundamental importance in programmable device in industrial automation, as they essential in order to active integration in production lines. In this paper, TBC(token bus controller) in the Mini-MAP board performs the function of the MAC sublayer, The LLC sublayer is implemented according to the specification of Class 3 that includes Type 1 and 3. And the MMS services are designed within the scope of implementation MAP 3.0 All the softwares are implemented under the real time executive for real time application of the Mini-MAP and they are loaded into PROMs at the network board. We tested the LLC functions to make use of a protocol analyzer for the token bus protocol. Also the MMS conformance test was carried out by exchanging primitives between a model system(including NIU) and a MMS product that had already passed the conformance the conformance test based on measurement method of network analysis.
