The definition of WSN
Definition[1]:
consist of large amount of sensor nodes
Multi-hop, self-organize
wireless communication
cooperative sensing, collection, process
Send to observe.
The difference between WSN and Ad hoc
The number of nodes
Sensor nodes are densely deployed
Sensor nodes are prone to failures
The topology of a sensor network changes very frequently
Routing protocol survey
Traditional technique
Flooding
Gossiping
Current routing technique
Flat-routing
Hierarchical-routing
Location-based routing
Gossiping
A slightly enhanced version of flooding where the receiving node sends the packet to a randomly selected neighbor which picks another neighbor to forward the packet to and so on.
Advantage: avoid the implosion
Drawback: Transmission delay
