Sensor nodes can use up their limited supply of energy performing computations and transmitting information in a wireless environment. Energy conserving forms of communication and computation are essential.
In a multi-hop WSN, each node plays a dual role as data sender and data router. The malfunctioning of some sensor nodes due to power failure can cause significant topological changes and might require rerouting of packets and reorganization of the network.
Time-driven (continuous)
Suitable for applications that require periodic data monitoring
Event-driven
React immediately to sudden and drastic changes
Query-driven
Respond to a query generated by the BS or another node in the network
Hybrid
The routing protocol is highly influenced by the data reporting method
The number of sensor nodes deployed in the sensing area may be on the order of hundreds or thousands, or more.
Any routing scheme must be able to work with this huge number of sensor nodes.
In addition, sensor network routing protocols should be scalable enough to respond to events in the environment.
