Directed diffusion: a scalable and robust communication paradigm for sensor networks

A really good paper on interest and data dissemination in sensor networks. Describes the “directed diffusion” paradigm, where “interests” are diffused throughout the network, and paths are “reinforced” to create gradients back to the data sinks. All communication is local, so nodes have no knowledge of the network topology. Unique addresses aren’t needed in the network, but nodes must be able to distinguish neighbours somehow. There’s probably quite a bit of work that could be done in diffusion based networks, such as development of a MAC layer protocol specifically designed for diffusion applications, however, seeing as the paper is from 2000, there’s probably already been work done, so I’ll have a good look around.
