Abstract Abstract Recently, linear wireless sensor networks (LWSNs) have been eliciting increasing attention because of their suitability for applications such as protection of critical infrastructures. Most of these applications require LWSN to remain operational for a longer period. However, the non-replenishable limited battery power of sensor nodes does not allow them to meet these expectations. Therefore, a shorter network lifetime is one of the most prominent barriers in large-scale deployment of LWSN. Unlike most existing studies, in this study, we analyze the impact of node placement and clustering on LWSN network lifetime. This research work has implemented and analyzed conventional clustering protocols such as Distributed Energy-efficient Clustering (DEEC), Developed Distributed Energy-Efficient Clustering (DDEEC), and Energy Efficient Scheme for Clustering Protocol Prolonging the Lifetime of Heterogeneous Wireless Sensor Networks (TDEEC) in context LWSN. First, existing node placement and clustering schemes have been categorized and classified for LWSN and various node placement schemes have been introduced for disparate applications. Then, we highlight the peculiarities of LWSN applications and discuss their unique characteristics. The research work has implemented and analyzed different node placement schemes for linear wireless sensor network. Simulation results use MATLAB clearly indicates that, Grid-Triangular node placement scheme, enhances network lifetime as compared linear sequential and linear parallel node placement scheme. The performance metric used in all node placement schemes is similar to DEEC, DDEEC and TDEEC based conventional clustering schemes. Grid Triangular node placement scheme improves 51 % network lifetime compared to linear sequential and linear parallel node placement schemes. Other than this, it has also been observed that, node placement and clustering schemes significantly affect LWSN lifetime. Keywords Linear wireless sensor networks, node placement, clustering, network lifetime, energy efficiency, performance analysis.
