Abstract

This paper proposes a MAC protocol for sensor networks such as disaster detection system which generate the non-periodic packet. B-MAC has been used to solve delay problem for sensor networks, however, the power loss occurs due to excessive preamble and over-hearing. In contrast, S-MAC has a number of drawbacks in power consumption due to synchronization. In this paper, we propose H-MAC and analyze its performance which has improved power consumption compared to S-MAC and overhead and over-hearing compared to B-MAC.

이 논문은 재난감지 시스템과 같이 비주기적 패킷이 발생하는 센서 네트워크를 위한 MAC 프로토콜을 제안한다. 기존 무선 센서 네트워크에 사용되던 B-MAC은 짧은 지연시간을 가지지만 과도한 프리엠블과 오버히어링으로 인한 전력손실이 발생하며, S-MAC은 동기화로 인한 전력소모가 많은 단점을 가진다. 따라서 이 논문에서는 S-MAC의 전력 소모를 개선하고 B-MAC의 오버헤드와 오버히어링을 개선한 H-MAC을 제안하고 성능을 분석한다.
