  • Recently MANET application is diversified studies on the MANET routing security and the reliable authentication mechanism is actively in progress. Stand-alone network structure of a MANET is an important field of ubiquitous computing environment of interest, Authentication techniques are already provided safety when applied to MANET reliability and efficiency in a secure authentication mechanism using the session key. However, most of the MANET environment, the model has been based on the assumption that the safety is guaranteed, When applied to an actual network situation, we can not rule out a variety of threats. This study is the testing and analysis to add the malicious node extracted at random to demonstrate the safety and efficacy of the session key certification techniques of the MANET environment.

  • Recently, rapid spreading of smart-phone make an expectation for increase of practical application for MANET(Mobile Ad-Hoc Network) which is not used infrastructure like as base-station. One of important application for MANET will be VoIP(Voice over Internet Protocol) known as Internet telephony. On the other hand, information intrusions causing serious problems is not allowed exception of MANET. Especially, there are some dangerous problems of intrusions to MANET, differently to other networks, because of it's usage of military purpose or emergency application of rescue. In this paper, to analyze this intrusion problem on MANET with blackhohe attacks, effect of intrusion to transmission performance is studied. VoIP traffic is assumed as an application service on MANET, computer simulation with NS-2 is used for this analysis.

  • The MANET(Mobile Ad Hoc Network) is an independent network that is oranized by only Mobile Hosts. MANET guarantees the mobility of the node and does not need a backbone network or a base station. Recently, there is a strong demand to connect MANET to the Internet. For the interconnection between MANET and Internet, Mobile hosts of MANET must have global IP address. The well known scheme of the address configuration for MANET is SAA(Stateless Address Autoconfiguration). SAA configurated IP address by node itself. The advantage of SAA is not requiring any server for address configuration. However the SAA has problems of unstable and inefficient interconnection on the AD Hoc Network. To solve this problem we propose a method that assigns an IPv6 Global address to the node through the Internet Gateway. The format of assigned IPv6 address is also defined. The simulation result demonstrates that the proposed method can support the host for fast getting of global IPv6 Address and Mobile IPv6 efficiently.

  • In large-scale MANETs, the performance of MANET routing protocols is degraded significantly. To avoid this, zone-based hierarchical architecture is proposed. In this architecture, single large-scale MANET is divided into multiple small-scale MANETs. In this paper, we propose autoconfiguration-coupled MANET routing protocol to reduce routing overhead of mim user nodes. If MANET routing protocol utilizes the autoconfigured information of each user node, its overhead or procedure can be reduced. Proposed method shows the degradation of routing overhead of user nodes via simulation.

  • MANET has some interest as a wireless mobile network supporting node mobility and having no additional infrastructure. Speed of mobile node on MANET is various from just slow speed of human's walk to vehicle's moving speed. In this study, VoIP performance of MANET is evaluated in the view of speed of mobile node. VoIP performance is studied on walking speed, vehicle speed and higher speed on MANET. PDR(Packet Delivery Ratio), MOS(Mean Opinion Score) are used as performance parameters.

  • As attack to routing function on MANET(Mobile Ad-Hoc Network), hole attack make cause some critical effects. MANET is easily influenced with hole attack and can be critically effected on transmission performance, because it is configured with terminal device as temporary network and dose not have effective means for malicious attack. In this paper, effects of grayhole attack to network performance on MANTE is analyzed with computer simulation. Voice traffic is used in simulation, effects of grayhole attack is compaerd with blackhole attack. The method and result of this paper can be used for data to study grayhoke attack.

  • MANET(Mobile Ad-hoc NETwork), a network characterized that its moving nodes freely constructs Network topology, has other different characteristics. Because Policy based Network Management in MANET guarantees QoS between nodes, it is essential in applied areas like VANET which targets safety and convenience. In this paper, we use COPS-PR which is appropriate Policy Exchange Protocol for MANET, and implement DiffServ-based QoS in the real networks and experiment its capability.

  • The demanding in construction of the stand-alone networks and interconnection between convergence devices have led an increase in research on MANET and the application of MANET has been paid much attention as a Ubiquitous computing which is growing fast in the field of computer science. With performance both as hosts and routers, easy network configuration, and fast response, mobile nodes participating in MANET are suitable for Embedded computing but have vulnerable points, about lack of dynamic network topology due to mobility, network scalability, passive attacks, and active attacks which make it impossible to manage continuous security authentication service. In this study, proposes S-EKE authentication mechanism for a robust authentication based on MANET and through identify wireless environment security vulnerabilities, currently being used in OTP S/Key and DH-EKE analyzes.

  • On account of limited resources and diverse topology change. it is difficult to manage MANET and guarantee QoS. In current MANET, QoS grantee is exceedingly significant. However, today's MANET are being concentrately worked on MAC protocols and routing protocols. Thus we proposed a framework for effective management of MANET and supporting QoS using policy based network management paradigm and active network technology. Since this framework employs the policy-based management approach in active network environment, it provides an abstract and autonomous management method to network managers.
