Abstract
The paper illustrates the design of MobEYE, a cooperative cache system for file transfer overMANETs. Its implementation is based on the sniffing facilities provided by the BSD Packet Filter, to process in-transit messages at the application level. MobEYE has been simulated, deriving support for the claim of saving energy and reducing latency; further possible optimizations, based on the use of promiscuous transmission mode, are discussed as well.
