A Cross-Layer Communication Protocol with Transmission Power Adjustment for Energy Saving in Multi-hop MhWSNs

摘要: Introducing a cross-layer scheme to optimize energy consumption in multi hop wireless sensor networks (MhWSNs) is relatively new approach. Moreover and contrarily the existing MhWSNs architectures, this paper deals with design based on three-ware architecture which exploits an inversed interaction between network, link physical layers. We propose hybrid efficiency protocol (named CL-HEEP) transmission power adjustment preserve reserves multi-hop MhWSNs. The main idea use of routing information dynamically adjust transceiver establish duty-cycling. An additional wake-up radio also implied by CL-HEEP while avoiding compulsory wake-up, idle listening, interference, collision problems. simulation reveals that energy-efficient able achieve significant performance improvement compared other protocols.
