Explain and motivate in-network processing for wireless sensor networks
What will be an ideal response?
In-network processing refers to processing performed at the nodes of the network, as opposed to processing performed outside the network on data gathered from the network. The nodes of a sensor network combine sensing, processing and communication. By processing data sensed from the node or routed through it, we can prevent unnecessary communication – which is a significant drain on power. For example, duplicated data can be surpressed; sensed values of no interest do not need to be forwarded.
