Center node: "uniform information exchange in multi channel wireless ad hoc networks"
  Abstract: In the information exchange problem, k packets that are initially maintained by k nodes need to be disseminated to the whole network as quickly as possible. We consider this problem in single-hop multi- channel networks of n nodes, and propose a uniform protocol that with high probability accomplishes the dissemination in O(k/F + F \cdot log n) rounds, assuming F available channels and collision detection. This result is asymptotically optimal when k is large (k \geq F^2 \cdot log n). To our knowledge, this is the first uniform protocol for information exchange in multi-channel networks.

Connected through hyperedge HE-1 (induced by source paper "scalable wake up of multi channel single hop radio networks"):

    - "packet latency of deterministic broadcasting in adversarial multiple access channels"
    - "broadcasting in ad hoc multiple access channels"
