무선센서 네트워크에서 네트워크 성능을 향상시키는 하이브리드 MAC 프로토콜

다국어 초록 (Multilingual Abstract)

In this paper we suggest a hybrid MAC protocol for wireless sensor networks(WSN) to enhance network performance. The proposed MAC scheme is specifically designed for wireless sensor networks which consist of lots nodes. The contributions of this paper are: First, the proposed scheduling algorithm is independent of network topology. Even though the BS node has lots of one hop node in dense mode network. all the time slots can be assigned fully without increasing frequencies. Second, BS one hop nodes can use more than one time slots if necessary, so total network performance is increased. We compare the network performance of the proposed scheme with previous one, HyMAC [1].
