A survey of node localization in wireless sensor networks using various Optimization algorithms

Wireless sensor networks (WSNs) encounter a variety of challenges as a result of their constrained resource and power restrictions for different network topologies. Due to the restricted resource limits and wireless transmission system characteristics, secure communication can be difficult. An extensive amount of study has been done to effectively optimize or minimize Direction of Arrival (DOA). The reduction of communication overhead can be improved through perfect node localization in wireless sensor networks (WSNs). In this survey, minimization of energy in sensor nodes problem has been addressed along with various optimization Meta heuristic algorithms. In this article, we examine the principal coverage optimization procedures and outline current unresolved questions in the field of energy-efficient covering.
