The analysis and simulation of wireless sensor networks routing protocol

Wireless sensor networks (WSN), which is made by the convergence of sensor, nested computation, networks and wireless communication technologies, is a new research area of wireless communication and computer science technology and has a wide application future. It is so important to design the suitable routing protocols because wireless sensor networks is confronted with many difficulties, such as limited communication ability, limited resources and mobile networks, etc. Up the foundation of the structure of wireless sensor networks, this paper firstly analysis and compares a few routing protocols of wireless sensor networks. Then compare directed diffusion to multicast and flooding in energy data from the theories. The results which simulated on the NS2 show that Directed diffusion is an ideal routing mode for WSN. In the last, we have a summary on the thesis, and look into the prospect of future research work.
