A multi-level FREAK DTN: Taking care of disconnected nodes in the IoT

Source nodes, which are responsible for collecting data, can either locally store the data or transmit them to the sink, a powerful node con- nected to the external world..

A common strategy to deal with message loss is to run a synchronizer algorithm, whose purpose is to generate a virtual (discrete) round structure at the application layer such that,

While three of the variants, namely the variant I that never forgets (= the original α-synchronizer), the variant II in which a process forgets when it makes a round switch, and

In this context, we wonder about the capacity of elite athletes to combine all these constraints, namely to manage the acceleration in their pace of life (Rosa, 2013) in order to

This simple example illustrates the fact that the use of a weighted or a non weighted graph for the join count statistics can have a strong influence on the result, depending on

Objective function The (linear) objective function for both our MILP and PB- SAT specifications asks to minimise the overall placement cost of the relay node, which is given by the

The first wireless repeater is connected to the central server using standard interfaces (for example, a virtual com-port over the USB interface). An exemplary network

Figure 5: Ratio of sent to received packets (RSRP) for trust, victim and malicious nodes during DoS attack As a result, the attack affects the energy consumption of the node..
