This paper looks at a new way to use multiple channels in ad-hoc sensor networks. It consists of two parts:
1) A protocol that allows a node, when sent a particular message, to attempt to change channel (reliably with a fall-back if the new channel is subject to interference).
2) An algorithm run at a single "command" node that selects which nodes should change channel according to a graph colouring problem.
The work is tested in simulation using Cooja (which simulates Contiki based sensor nodes).

This paper looks at P2P traffic over bittorrent from a large database
of torrents. The paper considers the effects of localising bittorrent
traffic on performance and ISP cost saving.
Data: The data set is one of the impressive things about this paper.
100K torrents of which 40K active. Demographics from 3.9M
concurrent users and 21M total users over a day from 11K ISPs.
Speed test results from ookla and iplane.
This paper creates software models of how P2P network topologies could wire up. It considers the possible strategies such as connecting to close nodes, connecting to random links and so on. Resilience and delay are considered.
