FANET에서 UAV간 링크 상태 예측에 기반한 라우팅 기법
황희두 한국멀티미디어학회 2016 멀티미디어학회논문지 Vol.19 No.11
Today, the application area and scope of FANET(Flying Ad Hoc Network) has been extended. As a result, FANET related research are actively conducted, but there is no decision yet as the routing protocol for FANET. In this paper, we propose the OLSR-Pds (Prediction with direction and speed) which is added a method to predict status of link for OLSR protocol. The mobility of nodes are modeled using Gauss-Markov algorithm, and relative speed between nodes were calculated by derive equation of movement, and thereby we can predict link status. An experiment for comparing AODV, OLSR and, OLSR-Pds was conducted by three factors such as packet delivery ratio, end to end delay, and routing overhead. In experiment result, we were confirm that OLSR-Pds performance are superior in these three factors. OLSR-Pds has the disadvantage that requires time-consuming calculations for link state and required for computing resources, but we were confirm that OLSR-Pds is suitable for routing to the FANET environment because it has all the characteristics of proactive protocol and reactive protocol.

In the information society, security policy must be prepared in order to manage organization's information safely and by the security policy, security system must be developed and security management must be done. In order to do that, Understanding is required about International Organization for Standardization's Information Security Management System(ISO/BS17799:2002) and the organization that wants to certificate by using that understanding or the cooperation's security environment must magnify Security System's Correctness and Effectiveness. In this paper, We will analysis Information Security Management System's concept and then show you analysis about standard item of the cooperation that wants to certificate or the organization certification.

정보화 사회에서 조직의 정보를 안전하게 관리하기 위해서는 보안정책이 마련되어야 하며, 이에 따라 보안시스템을 개발하고 보안정책에 따라 보안관리가 이루어져야 한다. 이를 위해 국제 표준화 기구의 정보보호경영시스템 (ISO/BS 17799:_ α )2) 에 대하여 파악하고 , 그에 따른 인증을 받고자 하는 기관이나 기업의 보안환경은 보안시스템의 정확성 (Correct-ness)과 효율성 (Effectiveness) 을 증대시켜야 한다. 본 논문에서는 정보 보호 경영시스템의 개념을 분석하여 인증 받고자 하는 기업이나 기관 인층에 대한 규격항목을 분석하여 제시한다.
