무선 센서네트워크에서 재밍 공격 방어를 위한 에너지 효율적인 라우팅 알고리즘

Abstract

WSN(Wireless Sensor network) has been actively applied for USN(Ubiquitous Sensor Network) services. In general, sensed data in WSN is vulnerable to malicious jamming attacks because this is normally transferred by a shared medium through air space. Accordingly, it is an important issue how to provide more resilient service against jamming attacks and how to select such a protection path which keeps energy efficiency in WSN consisting of sensor nodes equipped with limited power. In this thesis, we envisage the JARRA(Jamming Attack Resilient Routing Algorithm) scheme that detects jamming attacks and selects an optimal de-tour path guaranteeing energy efficiency and successful data delivery from the source node to the sink node. According to our simulation results, it is revealed that the JARRA scheme has superior resilience and energy efficiency compared with a method adapting LEACH(Low Energy Adaptive Clustering Hierarchy) routing scheme.
