Interference-Aware Routing for Multi-hop Energy-Constrained Wireless Network with SWIPT
Simultaneous wireless information and power transfer (SWIPT) can prolong the life of wireless nodes by harvesting energy and decoding information from a same RF signal, which changes the design of energy-constrained wireless network. In multi-hop wireless network, the interference generally exists. Route, interference and SWIPT are dependent. However, the exist works consider SWIPT link resource allocation with given route or only select path for only one flow without interference. Therefore, this paper analyze the influence of interference on SWIPT, and formulate the interference-aware SWIPT routing problem. The simulation results show that it can obtain more performance gains from interference and SWIPT with more flows.
