Abstract

This paper proposes a method of minimizing total energy consumption of IoT environment when communication devices in the network share the information directly. The proposed method reduces total number of transmission for the information sharing by using an effective network coding-based technique which dynamically selects a node and a data packet for each transmission. Simulation results show that the proposed method has better performance than an existing network coding-based method selecting transmission node in fixed order, a network coding-based method selecting transmission node in random order, and a uncoded method selecting transmission node in random order.

본 논문에서는 사물인터넷 환경에서 통신 기기들이 정보를 직접 공유하고자 할 때 전체 네트워크의 에너지 소모량을 최소화하기 위한 방식을 제안한다. 제안하는 방식은 매 전송 시 동적으로 전송 노드 및 전송 데이터를 선택하는 효과적인 네트워크 부호화 기법을 사용하여 정보 공유에 필요한 총 전송 횟수를 감소시킨다. 실험을 통하여 기존의 고정된 순서로 전송 노드를 설정하는 네트워크 부호화 방식, 랜덤한 순서로 전송 노드를 설정하는 네트워크 부호화 방식, 그리고 랜덤한 순서로 전송 노드를 설정하는 비부호화 방식에 비해 총 전송 횟수 측면에서 보다 뛰어난 성능을 가짐을 확인하였다.
