摘　　要：集成了传感器、微机电系统和网络3大技术而形成的无线传感器网络(WSN)是一种全新的信息获取和处理技术。无线通信模块是WSN节点最耗能的部件,节点标识是WSN节点每次通信必不可少的,减少发送数据量能够明显提高节点使用寿命,从匿名网络的角度考虑传感器网络节点分配问题,在分析了现有未知匿名网络标识分配算法缺陷的基础上,指出命名算法实现过程的3个阶段,并提出一种新的具有高效节能特性的分布式传感器网络节点分层动态ID分配(LDIA)算法,应用NS2仿真环境对该算法进行了验证,并同DFS算法、0-1-Split算法、L-P算法以及W&L算法对比,仿真研究结果表明,该算法不仅能够满足WSN部署方便、成本低廉、灵活的可扩展性,而且具有高效、节能等特性。Sensor network, which is made by the convergence of sensor, micro- electro- mechanism system and networks technologies, is a novel technology about acquiring and processing information. Wireless communication module is the most important component of the energy consumption on the WSN node boards, node identity is necessary in each communication with others. We consider the wireless sensor network （WSN） as a unknown anonymous network （UAN） and analyze the disadvantage of assigning distinct identities which have been proposed to nodes of an UAN. The paper discusses the three phases of the identity assigning, then presents a new Layered Dynamic Identification Assigning （LDIA） algorithm for WSN, which is a distributed and energy efficient solution. The performance of the LDIA is verified under the NS2 simulation environment and in comparison with the DFS,0 - 1 - Split ,L- P and W＆L methods, and a number of experiments are performed under the NS2 Simulation Environment. The simulation results indicate that the proposed algorithm can satisfy the requirements for flexible deployment, low cost, high scalability and it is more effective.
