On Optimal Throughput-Energy Curve for Multi-Hop Wireless Networks
Network throughput and energy consumption are two important performance metrics for a multi-hop wireless network. Current state-of-the-art is limited to either maximizing throughput under some energy constraint or minimizing energy consumption while satisfying some throughput requirement. In this paper, the authors take a multicriteria optimization approach to offer a systematic study on the relationship between the two performance objectives. They show that the solution to the multicriteria optimization problem is equivalent to finding an optimal throughput-energy curve, which characterizes the envelope of the entire throughput-energy region.
