| 摘要: |
| 提出一种用于提高无线传感器网络能效的双轮成簇协议(energy efficient double rounds clustering protocol，简称EEDRCP)。它对LEACH协议进行改进，以提高网络的能效。它在簇头选取算法中引入剩余能量参数，并且结合平面拓扑、层次拓扑和基于位置拓扑的优点形成混合型拓扑类型，同时改单轮成簇为双轮成簇。最后，在Matlab平台上模拟EEDRCP，并与LEACH和DIRECT协议进行分析比较。仿真结果表明，与LEACH协议相比，EEDRCP协议可提高网络能效达33% |

| Abstract: |
| This paper focuses on the communication aspect to present a protocol for WSN to improve energy efficiency. It is called Energy Efficient Double Rounds Clustering Protocol (EEDRCP). It improves the LEACH protocol as follows: it adds a parameter of energy for the head node’s election arithmetic, combines flat topology, hierarchical topology and location-based routing to form a hybrid topology, uses double rounds clustering instead of every round clustering. Finally, it is simulated on Matlab, and the results are compared with LEACH and DIRECT protocol. The results show that it improves the energy performance of network by 33%～82%. |
