摘要：The high reliability requirement of data transmission in wireless sensor networks has been a large challenge due to the random mobility and network topoloy instability, as well as restriction of energy consumption and system life time. In this work, the relationship matirx of distance and speed was created at first. Then the binay tree of mobility and reliabiliy was proposed based on the distance relationship matrix. The optimal relay nodes with high reliabiliy were selected by seeking the binay tree. The high reliable opportunistic cooperative data transmission scheme was presnted finally. The outcome of both mathematical analysis and NS simulation indicate that the proposed mechanism is superior to the traditional data transmission mechnism such as the reliability, system throughput and energy efficiency and so on.
