Exploit Non-Uniformities I:Tiered Architecture
Consider a memory hierarchy: registers, cache, main memory, swap space on disk
Due to locality, provides the illusion of a flat memory that has speed of registers but size & price of disk space
Similar goal in sensor nets: we want a spectrum of hardware within a network with the illusion of
- CPU/memory, range, scaling properties of large nodes
- Price, numbers, power consumption, proximity to physical phenomena of the smallest
