Power-aware epidemics

摘要

Epidemic protocols have been heralded as appropriate for wireless sensor networks. The nodes in such networks have limited battery resources. In this paper we investigate the use of power in three styles of epidemic protocols: basic epidemics, neighborhood flooding epidemics, and hierarchical epidemics. Basic epidemics turn out to be highly power hungry, and are not appropriate for power-aware applications. Both neighborhood and hierarchical epidemics can be made to use power judiciously, but a trade-off exists between scalability and latency.
