Aim at the problems of great overhead and the lower stability in Ad Hoc routing technology, an improved ant colony algorithm is proposed to study an ant-based Ad Hoc routing protocol. In our algorithm, the ant foraging, labor division and task allocation algorithm is the basic designation thinking.

针对已有Ad Hoc路由技术中存在的开销大以及网络稳定性较低的问题，本文引入蚁群算法，提出改进思想，将蚂蚁觅食和分工的方法作为路由设计的基本思想，研究基于改进蚂蚁算法的Ad Hoc路由协议，并与比较成熟的AODV(Ad Hoc On-Demand Distance Vector)做对比进行仿真。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
