nach der Bestellung gedruckt Neuware - Printed after ordering - A concepção de protocolos de rede seguros e rentáveis para redes de sensores sem fios (RSSFs) é um problema desafiante porque os sensores são dispositivos sem fios com recursos limitados. Uma vez que o custo de comunicação é o factor mais dominante no consumo de energia de um sensor, introduzimos um esquema de Encriptação e Chaveamento com Base em Energia Virtual eficiente para as RSSFs, que reduz significativamente o número de transmissões necessárias para evitar chaves obsoletas. Para além do objectivo de poupar energia, a transmissão mínima é imperativa para algumas aplicações militares das RSSF onde um adversário poderia estar a monitorizar o espectro sem fios. VEBEK é uma estrutura de comunicação segura onde os dados detectados são codificados utilizando um esquema baseado num código de permutação gerado através do mecanismo de encriptação RC4. A chave do mecanismo de encriptação RC4 muda dinamicamente em função da energia virtual residual do sensor.

Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
