Modeling the Behavior of the Linear Wireless Sensor Networks

Wireless Sensor Network (WSN) represents one of the considerably advanced technology trends. It was used in different applications for collecting, processing, and distributing a vast range of data. In order to monitor a specific type of infrastructure, a special type of WSN can be created by deploying or arranging a big number of sensors in a linear form, narrow curves, or sometimes in narrow rectangles and in thin circles. Such network topology is known as Linear Wireless Sensor Networks (LWSNs). The significant application of such networks is in monitoring different above and underground Pipelines, Railway lines, Bridges, Tunnels, Borderlines, and Highways. To ensure end-to-end packet delivery relying on a number of relay nodes, a transmission process must be efficient and reliable based on the shortest path approach or a backbone to prolong the network lifetime and improve its performance. In such networks, the sensors closer to the sink end up forwarding or relaying more packets than other distinct sensors. In this paper, a backbone is selected and a transmission process is performed by a simulation approach from the backbone nodes and other nodes. Any node outside the backbone selects the nearest backbone node and transmits to it. Different metrics were measured and analyzed.
