【 摘 要 】

Reliable data transmission of wireless body sensor networks with high quality of service requirement has been producing a new challenge. Considering the randomness and network dynamic condition, as well as restriction of system resources. In our paper, the network state information arrays of distance and channel quality were researched at first. Then the complete binay tree of network state and heap initialization were implemented. The optimal relay nodes were selected by heap sort approach. The data transmission scheme of reliable opportunistic cooperation was presented finally. The results of mathematics and simulation make clear that the proposed scheme have higher priority than the traditional transmission schemes in the matter of reliability, real time performance, energy efficiency and lifetime.
