Abstract

Rapid technological advances in the area of micro electro-mechanical systems (MEMS) have spurred the development of small inexpensive sensors capable of intelligent sensing. A significant amount of research has been done in the area of connecting large numbers of these sensors to create robust and scalable Wireless Sensor Networks (WSNs). The resource scarcity, ad-hoc deployment, and immense scale of WSNs make secure communication a particularly challenging problem. Since the primary consideration for sensor networks is energy efficiency, security schemes must balance their security features against the communication and computational overhead required to implement them. In this paper, we combine location information and probability to create a new security aware multipath geographic routing protocol. The implemented result in network simulator (ns-2) showed that our protocol has a better performance under attacks.

MEMS(Micro Electro-Mechanical Systems) 분야의 급격한 발전은 저비용의 정보 처리 센싱 능력을 갖춘 센서의 발전에 박차를 가했다. 이러한 기술의 흐름은 강력하고 높은 확장성을 가지는 WSNs(Wireless Sensor Networks)을 위하여 더 많은 센서 간 연결을 위한 연구가 진행되고 있는 실정이다. WSNs의 자원부족, Ad-hoc 배치방법, 보다 광대해지는 규모는 센서 간 통신에서 안전성을 보다 중요한 문제로 인식하게 하고 있다. 센서 네트워크의 주요 고려사항은 에너지 효율이기 때문에, 보안 기술은 통신에서의 보안 특징과 그것을 수행하기 위해 계산해야하는 오버헤드 간 균형을 맞춰야한다. 본 논문에서는 새로운 보안 인식 다중경로 위치기반 라우팅 프로토콜을 개발하기 위하여 위치정보와 전송확률을 결합한다. 네트워크 시뮬레이터(ns-2)를 실행한 결과 보다 나은 성능을 얻을 수 있음을 알 수 있다.
