Dtermination de la puissance optimale pour les rseaux de capteurs sans fil (WSN) by Ali Okhamila Yusuf Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Cet ouvrage traite de la détermination de la puissance optimale pour les réseaux de capteurs sans fil basés sur ZigBee. Lors de la conception des WSN, la puissance d'émission, la topologie du réseau et le schéma de routage sont pris en compte. Une transmission à faible puissance affecte la connectivité du réseau, tandis qu'une transmission à puissance excessive réduit la durée de vie des noeuds et augmente les interférences réseau. Il est donc nécessaire de déterminer la puissance optimale des noeuds afin de garantir la connectivité du réseau. Dans le cadre de ce travail, un prototype pratique de réseau de capteurs maillés sans fil ZigBee (WMSN) à auto-réparation et auto-configuration a été conçu afin d'évaluer les performances de la norme IEEE 802.15.4/ZigBee. Nous avons montré que l'augmentation de la puissance de transmission des noeuds de -6 dBm à 0 dBm dans les WMSN permettait d'améliorer le taux de livraison des paquets et le débit, et que la puissance optimale était de -2 dBm pour la topologie étudiée. Le banc d'essai aidera les concepteurs de réseaux de capteurs sans fil à prendre une décision précise sur la puissance de transmission et la topologie du réseau maillé en utilisant l'algorithme Ad-hoc on-demand distance vector (AODV) comme schéma de routage.

  1. Like new condition, safe packaging, good communication from seller. Fair price for the quality. Shipping was on time, but tracking information took over a week to receive. The book was as-described with minor cosmetic flaws (indentations in some pages, for example). I wish the listings showed the actual item being sold to you instead of just an accurate stock photo. This edition and appearance of George Orwell's 1984 here is a nice pocket-sized hardcover. I would buy from this shop again.

  2. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.

  3. Lightning fast shipping. Item arrived before the delivery date, perfect. Item arrived carefully packaged and was exactly as described. Very pleased.  Great communication throughout the process. Very attentive to detail and responsive. Will buy from again!  Had a small issue with the item, but the seller resolved it quickly. Great customer service!  The seller went above and beyond to make sure I was happy with my purchase. Highly recommended!
