We consider node localization problems in ad hoc wireless networks in which two types of nodes are considered: nodes with self-locating capability like GPS and nodes with no self-locating capability.… (More)
Ad-hoc networks that use the IEEE 802.11 MAC layer suffer from severe performance issues because nodes compete to access the wireless channel. In such a context, the network topology has a great… (More)
The molecular approach was introduced in the DESEREC project to describe large information systems in a manageable way. This level of abstraction bring to each person running a business service the… (More)
The molecular approach has been introduced at the beginning of the Deserec project to decrease the complexity of managing large mission-critical information systems. Actually it consists in a… (More)
