Paper Abstract

HASN is a hierarchical routing protocol for heterogeneous sensor networks, optimized via cross-layer designs to save sensor's power and improve reliability. There are two kinds of nodes in heterogeneous sensor networks: normal sensor and header node that has more powerful battery and higher performance antenna. A header and sensors in its radio transmitting range compose a cluster. The header takes charge of data collection and data aggregation in its cluster. In a cluster, the communication is unsymmetrical. From the header to sensors is directly reachable, but from sensors to their header needs multi-hop. In this paper, a new dynamic address assignment method is introduced for large number of sensors automatically. A mathematics model of energy optimum relay tree is designed, which can guarantee the minimum energy cost forwarding and relay load balance. We give an approximation algorithm to resolve the model. A centralized scheduling management is proposed to avoid collisions completely in a cluster. We also introduce a mechanism to depress data redundancy.
