Energy efficiency and network lifetime maximization in wireless sensor networks using Improved Ant Colony Optimization
TLDR
We propose a novel data collection scheme called Maximum Amount Shortest Path (MASP) using Improved Ant Colony Optimization, to address this issue, that increases network throughput as well as conserves energy by optimizing the assignment of sensor nodes. Expand
