Scalable and Secure Routing for Large-Scale Sensor Networks

Routing is an important issue in any type of networks. Multiple-hop based routing in sensor networks suffer performance downgrade from too many hops with the increase of the size of sensor nodes, as well as various attacks. A number of approaches have been proposed for routing in sensor networks, but they lack of sufficient support for secure routing in large-scale sensor networks. In this paper, we propose a scalable and secure routing protocol that can work energy-efficiently and resist most of attacks. By hierarchical and long-distance mesh routing, our protocol significantly reduces average number of hops for data transmission. Lightweight security mechanism enables the routing protocol to survive from most attacks against sensor networks.
