Directed diffusion is a well know routing algorithm for Wireless Sensor Networks (WSNs) that was designed in 2003. Directed diffusion saves energy by sending data packets hop by hop and by enforcing paths to avoid flooding. The main disadvantage of directed diffusion is that it is not aware of the network and nodes status and as a result cannot compare potential paths to find the best or healthier...
