| Summary: | An adaptive data gathering scheme was proposed for the application which different transmission quality was needed for different kinds of data. In the scheme, every sensor was associated with a forwarding probability parameter; every message was associated with an importance factor parameter. The two parameters determined adaptively the count of replication of a message, while meeting the transmission quality requirement and minimizing the network overhead. Experiment results show that the proposed data gathering scheme can achieve the tradeoff between transmission per- formance and network overhead. |
