Abstract

This paper investigates the use of cooperative multiple-input-multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) technique to limit energy consumption used to set up communications among distant hubs in a remote wireless sensor network (WSN). As energy exhaustion is a pertinent issue in WSN field, various methods aim to safeguard such asset, particularly by means for harvesting energy amidst communication among sensor hubs. One such widely utilized strategy is multi-hop communication to reduce the energy required by a single hub to transmit a given message, giving a homogeneous utilization of the energy assets among the hubs in the system. The case of multi-hop communication is not continuously more effective than single-hop. In multi-hop communication, energy efficiency will depend upon the distance between transmit and receive clusters. If the distance is large, then the energy expended will be less than single-hop communication. In this paper, an agreeable MIMO-OFDM transmission strategy for WSN is exhibited, which is contrasted with single-hop. The cooperation among adjacent nodes is analyzed, highlighting its points of interest in connection with both. The inference drawn from performance improvement manifests itself in the utility of applying the proposed strategy for energy-sparing purposes.
