Abstract

A Wireless Sensor Network is a network that is composed of wireless sensor nodes. There is no restriction on the place where it can be installed because it is composed wirelessly. Instead, sensor nodes have limited energy, such as batteries. Therefore, to use the network for a long time, energy consumption should be minimized. Several protocols have been proposed to minimize energy consumption, and the typical protocol is the LEACH protocol. The LEACH protocol is a cluster-based protocol that minimizes energy consumption by dividing the sensor field into clusters. Depending on how you organize the clusters of sensor field, network lifetimes may increase or decrease. In this paper, we will improve the network lifetime by improving the cluster head selection method in LEACH Protocol.

무선 센서 네트워크는 센서 노드들이 무선으로 구성되어 있는 네트워크이다. 무선으로 구성이 되기 때문에 설치 장소에 제약이 없다. 대신 센서 노드들은 배터리와 같은 제한된 에너지를 가지게 된다. 따라서 네트워크를 오랫동안 유지하려면 에너지 소모를 최소화하여야 한다. 에너지 소모를 최소화하기 위한 여러 프로토콜이 제안되었는데, 그 중 대표적인 프로토콜이 LEACH 프로토콜이다. LEACH 프로토콜은 클러스터 방식 프로토콜로 센서 공간을 클러스터로 나눔으로써 에너지 소모를 최소화한다. 클러스터의 구성에 따라 네트워크 수명이 증가할 수도 있지만, 오히려 수명이 단축될 수도 있다. 본 논문에서는 LEACH Protocol에서 클러스터 헤드 선출 방법을 개선하여 네트워크 수명을 향상시키고자 한다.
