차량용 무선 센서네트워크기반 저전력 스마트 키 시스템 구현

Wireless sensor networks are an emerging technology that promises to deeply impact the way computing device and humans interact with our environment. Given the lifetime, cost, and form-factor requirements for wireless sensor nodes, energy is usually the most important design constraint. In this paper, we present a design and implementation for smart key system for vehicle using low power wireless sensor network. In order to evaluate the life time of smart key system, we measure the real life time of our system. By experimental test, our system can operate more that 10 months with only one coin cell battery(CR2032).
