Wireless sensor networks are often constructed as asymmetric networks comprised of a large number of small, resource-constrained sensor nodes and a small number of relatively powerful base stations. A base station is vulnerable as a central point of failure in such networks. Typical packet traffic in a sensor network reveals pronounced patterns that allow an adversary analyzing packet traffic t...
