Abstract

We propose an efficient routing for wireless sensor networks, called pivot routing. Pivot routing establishes the data paths while query is propagated. Source node selects a data path and transmits data packets to the sink via pivot nodes. Because subsequent query and data packets are transmitted along pivot nodes, control message overhead decreases considerably. Network lifetime also increases since the energy consumption of communication is reduced at sensor node. Simulation results show good aspects of control overhead and network lifetime.
