WIRELESS SENSOR NETWORK [5 records]

Key distribution is an important issue in wireless sensor network(WSN) design. There are many key distribution schemes in the literature that are designed to maintain an easy and at the same time secure communication among sensor nodes.... Key distribution and key storage are more problematic in the cloud due to the transitory nature of the agents on it.

Cryptographie quantique [...] la difficulté de l'utilisation de «One Time Pad» [système inviolable] provient de la difficulté de la distribution des clefs. Comme une clef peut être une suite aléatoire de 0 et de 1, le problème est ramené au problème de l'acheminement d'une suite aléatoire de 0 et de 1 entre un émetteur et un récepteur, sans qu'elle puisse être interceptée par l'adversaire.

La mayor ventaja de la criptografía asimétrica es que la distribución de claves es más fácil y segura ya que la clave que se distribuye es la pública manteniéndose la privada para el uso exclusivo del propietario.

Wireless body area networks(WBANs) are a particular type of sensor network using wireless sensor nodes on a person's body to measure physiological parameters such as blood pressure, body temperature, heart rate, and blood sugar level, enabling a patient's health to be monitored remotely. WBANs can be either wearable or implantable.

OBS

Applications include but are not limited to: health and wellness monitoring[;] sports training (e.g., to measure performance)[;] personalized medicine (e.g., heart monitors)[;] personal safety (e.g., fall detection)[.]

A wireless sensor network(WSN) usually consists of numerous wireless devices deployed in a region of interest, each of which is capable of collecting and processing environmental information and communicating with neighboring devices. The problem of sensor placement becomes non trivial when we consider environmental factors such as terrain elevations. … Following a stepwise [sensor placement] optimization approach, we propose a crowd-out dominance search(CODS), which makes use of terrain information and intersensor relationship information to facilitate the optimization.

The... wireless soldier is expected to be equipped with a body area network consisting of a number of wireless products communicating with each other : PDA [personal digital assistant]/mobile phone, helmet/visor with head display, watch, weapon, supplies, cartridges, sensors on body or garment. All these systems can gather data, exchange data with each other and can give the soldier the essential info via his PDA, earplug, display, watch, etc. The wireless soldier is [connected] via phone and PDA... to the centric warfare system, his commander, the distributed sensor network on the battlefield and his fellow soldiers.
