Reliable Transmission Protocol for Wireless Sensor Network Based on Bitmap Index
摘要
Abstract
A Bitmap index based Reliable Data Transmission(BRDT) protocol applied in Wireless Sensor Network(WSN) which demands real-time upstream massive data transmission, is proposed. In the BRDT, data generated by the sensor nodes are transferred through several iteration cycles. Each iteration cycle contains a retransfer-free data flow and an index packet transmission through back channel to recover lost packets. The performance of the BRDT is obtained from simulation and is verified on the Z-EYE system, results show that compared with the RMST, the BRDT has less service demanding on lower layer, the BRDT has better performance improvement than the widely used NACK refransfer method in high packet loss rate networks, and the BRDT has better transmission efficiency than the PSFQ in the same test situation.关键词
