Research and design of protocols based on density of nodes for sensor networks

The routing technology plays an important role in wireless sensor networks, and there are many aspects that are essential to the design of the routing protocols. The routing protocols especially the clustering-based protocol, are studied; and we found that the traditional clustering algorithms such as LEACH couldn't work well in the head-node election as well as the size of the cluster. Aiming at this point, we designed a clustering routing protocol based on the density of nodes; in this protocol, the heads were elected based on the density of nodes; and simulation shows that we get a better distribution of the head-nodes and make the energy consumption more efficient.
