Analyzing the proliferation of item-level RFID, recent studies have identified the cost sharing of the technology as a gating issue. Various qualitative studies have predicted that conflict will arise, in particular in decentralized supply chains, from the ...
We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...
A network user’s decision to start and continue using security products is based on economic considerations. The cost of a security compromise (e.g., worm infection) is compared against the cost of deploying and maintaining a sufficient level of security. ...
For a class of sensor networks, the task is to monitor an underlying
physical phenomenon over space and time through a
noisy observation process. The sensors can communicate back
to a data collector over a noisy channel. The key parameters
in such a se ...

We consider the problem of routing in a wide area mobile ad-hoc network called Terminode Network. Routing in this network is designed with the following objectives. First, it should scale well in terms of the number of nodes and geographical coverage ...
An algorithm that pre-computes a list of routes for each node in the network. An alternate route is also computed in case of overload of the primary one. Simulations show that this algorithm provides routes as good as On-Demand ones. ...
The design of a mechatronic system in an industrial context is alwais affected by cost. Either the performances have to be optimized for a given cost or the cost must be minimized for the given performances. ...
The Institute of Radiation Protection and Nuclear Safety (France) is planning the set-up of an automatic nuclear aerosol monitoring network over the French territory. Each of the stations will be able to automatically sample the air aerosol content and pro ...
This paper presents an efficient simplification method for regular meshes obtained with a binary subdivision scheme. Our mesh connectivity is constrained with a quadtree data structure. We propose a quadtree built especially for this class of meshes having ...
