A Triangle-Based Localization Scheme in Wireless Multimedia Sensor Network

Wireless Multimedia Sensor Networks (WMSNs) have emerged as a significant research topic aimed at improving the flexibility of power distribution networks. The stability of a power distribution network may be greatly influenced by the precision and energy use of sensor node localization, especially when using Wireless Sensor Networks (WSNs). This work introduces a suggestion for a modified triangle-based localization scheme (MTBLS) with the objective of enhancing the performance of the conventional mid-normal-based localization scheme (MBLS) and the triangle-based localization method (TBLS). The aim of this study is to effectively meet the communication needs associated with smart distribution automation. The proposed strategy aims to create a triangular configuration by establishing a connection between two anchor nodes located on one side of the triangle. The RSSI (Received Signal Strength Indication) value is used to measure the signal strength between the two anchor nodes and the unknown node, which are positioned on the remaining two sides of the triangular configuration. The simulation was performed using the NS-2 Tool, and afterwards, the acquired outcomes were compared with the performance of the existing MBLS and TBLS algorithms. The results indicate that the use of MTBLS has resulted in improved accuracy in the localization of nodes when compared to presently available methods. In addition, there has been a significant decrease in energy consumption across the whole of the power distribution network, which has coincided with a reduction in the quantity of iterations.
