Enhancement of the Reliability of the Linear Wireless Sensor Networks

Abstract

Wireless Sensor Network (WSN) is one of the trend technologies. It was aggregation, processing, and transferring a huge amount of data in different applications that deal with the surrounding environment. Using a huge number of sensors deployed or organized in a linear configuration between two parallel lines or carvings, a specific kind of WSN is constructed to monitor a particular type of infrastructure. This type of WSN is Known as Linear Wireless Sensor Network (LWSN). LWSNs are used in monitoring applications that are arranged in linear form like underground Pipelines, Bridges, Tunnels, Railway lines, Highways, and Borderlines. A transmission process must be reliable and efficient to ensure end-to-end packet delivery. The backbone or the shortest path approach is used to improve the network performance and prolong the network lifetime. In such networks, more packets are ultimately forwarded or relayed by the sensors closest to the sink than by other types of sensors. In this paper, a backbone approach has been implemented where data is sent from the backbone and the node outside the backbone. Any node outside the backbone selects the closest backbone and sends the sensing data to it.
