Abstract

In this paper, we propose a new location service and location-based routing for data dissemination from a source to a mobile group sink in less energy consumption of the sensor node. Unlike the existing protocols, the proposed protocol uses a leader sink instead of a group area as the location information to represent a mobile sink group. The proposed protocol also uses grid leaders on virtual grid structure to support sink mobility in location service. By using a leader sink as a representative and grid leaders for mobility supporting, the proposed protocol can exploit an efficient hierarchical location service and data dissemination method without using flooding. Accordingly, the proposed protocol carries out upper layer location services and data dissemination between a leader sink and a source and lower layer location services and data dissemination between the leader sink and member sinks. Simulation results demonstrate that the proposed protocol achieves energy-efficiency.

본 논문은 센서 노드들의 에너지 소비를 줄이고 소스로부터 이동 싱크 그룹까지 데이터를 전달하기 위한 새로운 위치 서비스와 위치 기반 라우팅을 제안한다. 기존 방안들과는 다르게, 제안 방안은 그룹 영역 대신 싱크 그룹을 대표하는 리더 싱크 위치 정보를 사용한다. 그래서, 제안 방안은 소스와 리더 싱크 간의 위치 서비스와 위치 기반 라우팅을 위한 상위 계층과 리더 싱크와 멤버 싱크들 간의 위치 서비스와 라우팅을 위한 하위 계층으로 이루어진 계층적 위치 서비스와 위치 기반 라우팅을 사용한다. 각각의 상위와 하위 계층의 위치 서비스와 위치 기반 라우팅은 플러딩을 사용하지 않기 때문에 제안 방안은 센서 노드들의 에너지 소비를 줄일 수 있다. 다양한 시뮬레이션 결과는 제안 방안이 기존 방안보다 우수함을 증명한다.
