摘要

In a linear wireless sensor network (LWSN), all sensor nodes are strategically positioned along a strictly linear or semi-linear configuration to monitor linear infrastructure systems, including railways, bridges, oil/gas pipelines, and more. The reliability of LWSNs is critical for their successful deployment. Most existing studies focus primarily on the reliability analysis of unidirectional LWSNs, whereas bidirectional LWSNs (BLWSNs) deployment strategy is also widely used. Thus, this paper presents a reliability evaluation method for BLWSNs based on backtracking and provides a comparative analysis for the performance comparison between unidirectional LWSNs and bidirectional LWSNs based on different metrics. We have performed simulations on LWSNs of various dimensions to illustrate the suitability of the proposed method in different LWSN scenarios. The proposed algorithm consistently outperforms the previous approach in time complexity when n \(\ge \) ≥ 5, achieving a minimum optimization rate of 21.88% and demonstrating increasing efficiency as ‘n’ grows. These results offer valuable insights into the design and deployment of dependable LWSNs.
