초록
산업계를 중심으로 최근에는 위치에 구애받지 않고 다양한 서비스를 자유롭게 이용하고자 하는 수요가 급증하면서, 비용 효율적이고 구축이 용이한 wireless mesh network (WMN) 솔루션이 다시 주목받고 있다. 본 논문에서는3차원 WMN을 위한 라우팅 솔루션인 Autonomous Load-balancing Field-based Anycast routing+ (ALFA++)의구현 이슈를 심도 있게 살펴본다. 이후에는 저가 상용 장치를 활용하여 구축한 대학 캠퍼스 건물 내 802.11 기반 3차원WMN 테스트베드에서 ALFA+의 성능을 평가하고 이를 통해 궁극적으로 ALFA+의 실제 활용 가능성을 검증한다. 기존대부분의 연구는 가상환경 기반 시뮬레이션을 통한 성능평가를 한 반면, 본 연구에서는 실환경 테스트베드에서 상용장치를 활용한 성능평가 수행을 위해 필요한 구현 관련 상세정보를 소개하고 실환경 테스트베드에서의 결과를 기반으로ALFA+의 실질적인 가치를 평가했다는 점에서 큰 의미가 있다.
Abstract
In response to the increasing demand for unrestricted access to diverse services regardless of location, cost-effective and easily deployable Wireless Mesh Network (WMN) solutions have once again captured attention. This paper primarily addresses the implementation challenges of Autonomous Load-balancing Field-based Anycast routing+ (ALFA+) for three-dimensional (3D) WMNs. Subsequently, we evaluate the performance of ALFA+ in an 802.11-based 3D WMN testbed established within a university campus using commercial devices, thus validating the practical viability of ALFA+. While most prior research has relied on performance evaluation through virtual environment simulations, this study distinguishes itself by performance evaluations in a real-world testbed using commercial devices and providing detailed implementation-related information necessary for such evaluations. This approach holds considerable significance in assessing the actual applicability of ALFA+.
