You are presented with multiple paper abstracts, alongside the associated literature review and chapter titles. Given the provided information, you are going to do a literature review. Please generate a coherent literature review that synthesizes the content, draws connections between different works, highlights major findings, and identifies any gaps in the existing research.

Literature Review Title: A Comprehensive Survey of Recent Advancements in Molecular Communication 
Chapter Title:  IV. MACROSCALE MOLECULAR COMMUNICATION 
1. Abstract of Cited Paper (BIB001):  We instrumented large civil engineering infrastructure items, such as bridges and tunnels, with sensors that monitor their operational performance and deterioration. In so doing we discovered that commercial offerings of wireless sensor networks (WSNs) are still geared towards research prototypes and are currently not yet mature for deployment in practical scenarios. We distill the experience gained during this 3-year interdisciplinary project into specific advice for researchers and developers. We discuss problems and solutions in a variety of areas including sensor hardware, radio propagation, node deployment, system security and data visualization. We also point out the problems that are still open and that the community needs to address to enable widespread adoption of WSNs outside the research lab.

Literature Review:
Although use of molecular communication for long range communication between nanomachines has been proposed in BIB001 , engineering a truly macroscale molecular communication system has not been considered in the past. In this work we refer to macroscale molecular communication as a system where the dimensions of the transmitter, receiver, and the distance between them is a few cm or more. These systems have not been considered in the past partly because of the availability of wireless radio technology at these scales, which is very fast and reliable. Nevertheless, there are application for which use of radio technology is not possible or desirable, and molecular communication may be a suitable solution. For example, use of radio based sensor networks for infrastructure monitoring in urban areas can be inefficient and unreliable BIB002 . Therefore, in this section we discuss the physical components required for macroscale molecular communication.
