Abstract
The set of frames of an in-vehicle application must meet two constraints: it has to be feasible from a schedulability point of view and it should minimize the network bandwidth consumption. The latter point is crucial for enabling the use of low cost electronic components and for facilitating an incremental design process. This study proposes two heuristics for the NP-complete problem of generating a set of schedulable frames that minimizes the bandwidth usage. The proposed strategies are complementary. The first one can be applied to large size problems (in the context of in-vehicle applications) while the second one, slightly more efficient in our experiments, is limited to small size problems (less than 12 signals emitted by each stations). These proposals has proved to be effective in comparison with other possible strategies.

feasible from a schedulability point of view and it should minimize the network bandwidth consumption. The latter point is crucial for enabling the use of low cost electronic components and for facilitating an incremental design process. This study proposes two heuristics for the NP-complete problem of generating a set of schedulable frames that minimizes the bandwidth usage. The proposed strategies are complementary. The first one can be applied to large size problems (in the context of in-vehicle applications) while the second one, slightly more efficient in our experiments, is limited to small size problems (less than 12 signals emitted by each stations). These proposals has proved to be effective in comparison with other possible strategies.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Nancy</li></settlement><orgName><li>Institut national polytechnique de Lorraine</li><li>Université Nancy 2</li><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Santos Marques, Ricardo" sort="Santos Marques, Ricardo" uniqKey="Santos Marques R" first="Ricardo" last="Santos Marques">Ricardo Santos Marques</name></region><name sortKey="Navet, Nicolas" sort="Navet, Nicolas" uniqKey="Navet N" first="Nicolas" last="Navet">Nicolas Navet</name><name sortKey="Simonot Lion, Francoise" sort="Simonot Lion, Francoise" uniqKey="Simonot Lion F" first="Françoise" last="Simonot-Lion">Françoise Simonot-Lion</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
