摘要: The evaluation of link quality plays a vital role in designing the upper level protocol wireless sensor networks. high rate packet loss occurs when data is transmitting on poor link, thus resulting retransmission and energy waste. Motivated with aforementioned problem, we present weight model to address problem consumption. This regards node's power as an adjustment factor. It fuses parameter nodes' mathematically formulate above for decreasing interference making network balanced. Then exploiting method function derivation, validate analytical solution weight. On basis this model, distributed topology construction algorithm improve efficiency proposed. Finally several simulation experiments are conducted evaluate performance its theoretical properties. Theoretical analyses results show that can enhance steadiness, decrease prolong network's lifetime. Display Omitted A represents bi-directional communication proposed.The lessen waste, increase throughput.The relies all links network.
