多信道无线Ad Hoc网络中的统一信息交换

Uniform Information Exchange in Multi-channel Wireless Ad Hoc Networks

摘要:

在信息交换问题中,最初由k个节点维护的k个数据包需要尽可能快地传播到整个网络。我们考虑了n个节点的单跳多信道网络中的这个问题,并提出了一个统一的协议,该协议在O(k/F + F \cdot log n)轮中以高概率完成分发,假设F个可用信道和冲突检测。当k很大(k \geq F^2 \cdot log n)时,该结果是渐近最优的。据我们所知,这是第一个在多信道网络中进行信息交换的统一协议。

英文摘要:

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.
