What is data centric routing?
The main idea of the data centric routing or data aggregation and in-network processing approaches is to combine the data arriving from different sources (sensor nodes) at certain aggregation points (or simply aggregators) and route, eliminate redundancies by performing simple processing at the aggregation points, and …
What do you mean by data centric storage?
With Data Centric Storage (DCS), when a sensor measures a physical event for a particular data type, it pushes the information towards the rendezvous node in charge of that data type. In turn, consumers interested on that data type query that particular rendezvous node to retrieve the information.
What is content based networking model?
A content-based network is a novel communication infrastructure in which the flow of messages through the network is driven by the content of the messages, rather than by explicit addresses assigned by senders and attached to the messages.
What is data centric network in WSN?
In Wireless Sensor Networks, data centric routing is used to control the redundancy of data. This is because the sensors nodes don not have global identification number which specifies them uniquely; hence data is transmitted to each node with significant redundancy.
What is data centric testing?
Data-centric testing’s core function is to test the ETL processes to ensure that the data loaded into a data warehouse is accurately inserted into the data warehouse tables. The source data is typically not stored in the data warehouse; therefore, it has to be extracted from one or more source databases.
What is a data centric organization?
A data-centric organization is one in which people, technologies and processes are designed and developed with a clear intent of generating relevant information and utilizing it collaboratively to enhance the business success of an organization.
What is Leach algorithm?
LEACH is a hierarchical protocol in which most nodes transmit to cluster heads, and the cluster heads aggregate and compress the data and forward it to the base station (sink). Each node uses a stochastic algorithm at each round to determine whether it will become a cluster head in this round.
What are the types of test data?
What are the types of test data?
- Boundary Test Data:

- Absent Data:
- Manual Test Data Creation:
- Back-end Data Injection:
- Automated Test Data Generation:
- Third-party Tools:
What is data centric integration?
The Process “Data-centric” refers to an architecture in which data is the primary and permanent asset, while applications and use cases may come and go. It is a step beyond being data-driven.
What is difference between gossiping and flooding?
Flooding is a simple routing algorithm in which all the incoming packet is sent to every outgoing link except the one it arrived on. In gossip protocol the node chooses a random neighbor from the list of neighbors and passes the message to the neighbor. This process is repeated until we reach the destination node.
Which protocol is used in WSN?
Dynamic source routing (DSR) is a routing protocol used in wireless sensor networks developed at CMU in 1996. Dynamic source routing can be reactive or on demand.
