In sensor network, the importance of transporting data with reliability is growing gradually to support communications. Data flow from sink to nodes needs reliability for the control or management, that is very sensitive and intolerable, however relatively, data flow from nodes to sink is tolerable. In this paper, with emphasis of the data flow from sink to nodes, we proposed the mechanism that establishes confidence interval for transport. Establishing confidence interval herby-hop, not end to end, if errors happen or there's missing data, this mechanism recovers them with selective acknowledgement using fixed window. In addition, this mechanism supports franc congestion control depending on the buffer condition. Through the simulation, we showed that this mechanism has an excellent performance for error recovery in sensor network.

정보통신 기술이 다양하게 발달함에 따라 인터넷망을 통한 음성통신 및 데이터 통신의 필요성이 대두되고 있다. 인터넷망을 통해 음성통신뿐만 아니라 데이터통신등을 단일 형태로 전달하는 것 외에 멀티미디어 정보를 복수의 통신로를 통해 전달할 수 있는 교환시스템을 설계 하였다.

Meteor Burst Communication can provide effective and economical means of communication where long distance VHF NLOS(None Line of sight) data transmission is needed; often ranges more than 1200 km. It has been, however, so far considered unsuitable for distance as short as 700km application because of phenomenal decrease in burst durations, which leads to decreation of total duty rate of the system. This paper introduce experimental characteristics of very shot distance MB(Meteor Hurst) path. Also the occurring rate and average length measured on 50km paths between kyongsan-city to Andong-city shows that Meter Burst communication is useful communication system in mountain and valley communication.
