what is a transducer?
Transducers are devices that convert energy from one form to another.
What is a gateway in Fog architcture?
Fog devices that connect sensors to the Internet are generally called gateways.
What are the routing issues faced in MANET?
◦ Frequent route changes
◦ Relatively low data rate links which is made worse by mobility
what is logic based context modelling?
Logic defines conditions on which a concluding expression or fact may be derived from a set of other expressions or facts (reasoning)
context is defined as facts, expressions and rules
High degree of formality – Cannot inherently deal with uncertain or conflicting information
Suit better in cases, where we are certain about the quality of the collected data
Standard Retrieval Method: Inference
What are homogeneous nodes in MANET?
all nodes use the same communication protocol
What is an actuator ?
actuators do the opposite of an input transducer. They take electrical signals and convert them into another form of energy.
What are the requirements of context modelling?
1. Heterogeneity and mobility
2. Dependencies
3. Timeliness
4. Imperfections
5. Reasoning
6.Usability of modelling formalisms
7. Efficient context provisioning
What affects the node connectivity in MANET?
1. dynamic nature of wireless medium
2. node mobility departure /arrival
3. power outage
In MANETS what are heterogeneous nodes?
Nodes use different protocols for communication
How to convert change in resistance to change in voltage??
Using a voltage divider or Resistance Bridge with instrumental amplifier
What is hierarchal topology in MANET?
Each group of nodes can communicate with one master only, if not available store data until available
What is MANET flat topology?
All nodes are on the same level, any node can communicate with any node.
