A comparison of four systems related to the routing protocols of sensor networks

Sensor networks, both wired and wireless, are popular, sensitive, and very useful in various real-time applications and processing. Routing in sensor networks is very difficult and complex because they are asymmetric and symmetric links. This paper compares four different systems and state the various criteria such as energy consumption, asymmetry, overhead, delivery rate, performance, etc. This is not a statement of superiority.
