An approach to detect abnormal activities based on reputations created individually by each node is vulnerable to a false accusation since intrusion detection in ad-hoc networks is done in a distributed and cooperative manner. Detection of false accusation is considered important because the efficiency or survivability of the network can be degraded severely if normal nodes were excluded from the network by being considered as abnormal ones in the intrusion detection process. In this paper, we propose an improved reputation-based intrusion detection technique to efficiently detect and manage false accusations in ad-hoc networks. Additionally, we execute simulations of the proposed technique to analyze its performance and feasibility to be implemented in a real environment.

최근 SNS나 소셜미디어등 온라인을 통해 고객들의 서비스에 대한 정성적인 평가 및 요구사항이 실시간으로 표현되고 있으므로 병원, 은행,회사 등 각 기업에서는 서비스에 대한 부정적인 여론이 확산되기 전에 능동적으로 대응할 수 있는 시스템의 필요성이 요구되고 있다. 기존의 정형화된 설문을 통한 고객 니즈 분석으로는 다양한 온라인 플렛품 상의 소비자 경험, 의견 및 감성을 분석하기가 어렵다. 따라서, 다양한 온라인 플렛폼의 등장 소비자 Life-Style의 변화 등으로 기업이 시장과 고객들의 행동패턴을 파악 및 예측하여 분석, 관리하고 대응할 수 있는 시스템이 필요하다. 본 연구에서는 기업의 마케팅, 홍보, 기획 등 B2C 서비스 기업 활동에 효율적으로 활용할 수 있는 고객 평판분석 관리 시스템을 제안한다. 특히, 제안한 시스템의 효율성 검증을 위해 실제 테스트베드 프로토타입을 개발한다.
