There are several avenues for future work. We hope to increase the accuracy of our methodology by accounting for the impact of four factors that we ignored in this paper. These four factors are: (i) retransmissions of lost unicast packets, (ii) RTS/CTS handshake (iii) collisions between data and ACK packets (iv) autorate algorithms.
We would like to extend our approach to estimate interference among larger groups of links, instead of just pairwise interference.
Finally, we note that our methodology requires nodes to generate broadcast traffic, and existing traffic on the network can significantly reduce the accuracy of our approach. We are currently exploring the possibility of determining interference patterns by simply observing correlation between existing traffic flows on the network.
