摘　　要：Energy efficiency is the most important goal in wireless sensor network routing and self-organization algorithms. To achieve this goal, our paper first presents a distributed energy-aware routing algorithm Nearest to Theoretical Point（NTP）. Then it applies NTP to self-organization of sensor networks to form an energy-efficient self-organization algorithm Shortest Path Tree-NTP（SPT-NTP）. Theoretic analysis and simulation show that NTP and SPT-NTP can ensure less network energy consumption than other related algorithms.Energy efficiency is the most important goal in wireless sensor network routing and self-organization algorithms.
