This paper proposes M(3)A-multicast mobile measurement architecture-a softw
are architecture for the development of flexible distributed measurement sy
stems. M(3)A centers at the large level on modern Internet technologies suc
h as multicast and mobile computing and at the small level on a Java and ac
tor-based framework. M(3)A allows the building of open, portable, and dynam
ically reconfigurable systems, The paper describes the architecture and exe
mplifies it by some examples.
