Recent work has shown that wireless links are not independent, and that transmissions from a transmitter to multiple receivers are correlated. This finding has profound implications for the performance of network protocols such as broadcast, multicast, opportunistic routing, and network coding. In this paper, we show how link correlation can significantly impact broadcast. We present the design and implementation of CorLayer, a general supporting layer for energy-efficient reliable broadcast… CONTINUE READING

Key Quantitative Results

  • The experimental results show that CorLayer significantly improves energy efficiency across a wide spectrum of broadcast protocols and that the total number of packet transmissions can be reduced consistently by 47% on average.
  • The experimental results show that CorLayer remark­ably improves energy ef.ciency across a wide spectrum of broad­cast protocols and that the total number of packet transmissions can be reduced consistently by 47% on average.
