Abstract
Wireless sensor networks (WSNs) have attracted significant interests of many researchers because they have great potential as a means of obtaining information of various environments remotely. WSNs have their wide range of applications, such as natural environmental monitoring in forest regions and environmental control in office buildings. In WSNs, many sensor nodes with such resource limitation as battery capacity, CPU, and communication capacity are deployed in a region and used to monitor and gather sensor information of environments. Therefore, scalable and efficient network control for saving energy consumption is needed to prolong the lifetime of WSNs. Ant-based algorithms have attracted attentions as routing algorithms for energy consumption savings because they are more robust, efficient, and scalable than other conventional routing algorithms. This paper proposes a new advanced ant-based routing algorithm for large scale WSNs, which is more efficient and scalable than conventional ant-based routing algorithms. We evaluate the proposed algorithm using computer simulations and verify its effectiveness.
