In the modern era, wireless sensor network has turned into a critical innovation for various sorts of the clever algorithms, where nodes localization was complicated in research territory. A significant number of the advantages for wireless sensor networks are not profitable without a priory is known. Including Global Positioning System to every node is an exclusive plan and unsuitable for the indoor condition. Localization is a critical piece for wireless sensor networks innovation while current localization approaches, for the most part 2D plane has been concentrated, the rising 3D localization conveys WSNs nearer to improved exactness, and the 3D area innovation is more fitting for genuine applications. In any case, existing 3D localization has weaknesses, for example, high time complexity, low positioning exactness, and awesome energy utilization. Going for the current issues in present 3D localization methods, enhanced 3D localization technique based on adaptive stochastic control is proposed. Simulation results show that the average area precision of adaptive stochastic localization algorithm is vastly improved than established 3D DV-hop algorithm and centroid algorithm. Besides, the stability of the proposed method is superior to others. Anchor node system and propagation sample determination is used to simulate the spread of accuracy by 78.9% compared with 3D DV-HOP and 92.7% compared with the 3D centroid.
