“…The LWSN-based system in [15] is proposed as an alternative to traditional cathodic protection (CP) monitoring of oil and natural gas pipeline systems. Contrary to traditional CP monitoring systems, as a novelty, the proposed system is designed to be used in extreme environments (deep valleys, desserts, etc.)…”

I n the past few years, Wireless Sensor Networks (WSNs) have been evolving in many different aspects such as agricultural, industrial, and surveillance. In order to collect sensor data, the wireless nodes are deployed in an area with a specific network topology. Although there are various network topologies to deploy WSNs, the geographic conditions of the given area and the purpose of the application have still vital importance to decide the structure of network topology. Especially, when linear structures like pipelines, railways, roads or tunnels need to be monitored, WSN are formed as linear network topology which is known as linear-WSN (LWSN) [1].In a typical LWSN, the sensor nodes are communicated within a hierarchical order. The hierarchical structure requires the single-hop communication model between the transmitting and receiving nodes. Generally, for an outdoor deployment, the communication range between these nodes is desired to be kept as high as possible. For this reason, it is necessary to use proper

Time synchronization is fundamental in the distributed networked systems, especially in Wireless Sensor Networks where a global time is essential to make sense of the events like collection of data and scheduled sleep/wake-up of nodes. There exists numerous time synchronization algorithms and techniques in the literature. Nonetheless, these proposed methods lack realistic experimentation of the synchronization process which is vital from the realization point of view. This study aims to bridge that gap by presenting a distributed lightweight time synchronization protocol implemented on an inexpensive PIC platform. Furthermore, PIC-based systems hadn't been investigated before and gives an idea of the simplicity of the algorithm. Experimental analysis was done to see the performance of the protocol. The core motivation of the experiments was to the study the impact of the environment (e.g. indoor, outdoors, temperature variations and interference) on the synchronization. Our findings show that temperature indeed impedes the synchronization accuracy.

Recently, a concept of linear wireless sensor networks (LWSNs) has attracted much attention. For such networks, one of the key challenges in sensor node design is to couple transceiver modules with bidirectional antennas placed back-to-back for opposite radiation. As is known, simply, this can be achieved by using well-known coupling options like radio frequency (RF) switch or splitter. However, it is important to decide between two seemingly equally good options according to the system requirements such as RF performance, power consumption, and cost. Therefore, this study aims to comparatively assess these options from the system level point of view to find out what advantages or disadvantages either provides as per the other from widespread use of them in a LWSN-based cathodic protection monitoring of oil and natural gas pipelines in extreme environments. Preliminary field tests are also conducted to validate the efficiency of coupling options for LWSN links. Results show that RF splitter offers low power consumption and cost whereas RF switch has advantages of low loss. Thus, it is believed that this study may provide useful insights to design bidirectional sensor links for LWSNs.
