Optimization Deployment of WL-MESH Network with Base-station in Nature Environment

摘要

Wireless Mesh network is a robust and dynamic multi-hop network. Compared with traditional wireless networks, wireless Mesh networks have many advantages, such as good reliability, high bandwidth, low deployment cost, wide coverage, and good scalability. Therefore, wireless MESH network has become the most ideal wireless network solution. The deployment location of Mesh base-station nodes can affect the performance of wireless Mesh networks to a great extent. Therefore, finding an appropriate and effective Mesh router node deployment scheme is the key to improve network performance. At present, Mesh network has been applied in smart city, but it is rarely used in the field. Based on the 3D mountain environment in the Wanglang national nature reserve of Sichuan province, this paper conducts an in-depth study on the deployment algorithm of wireless Mesh network nodes. In this paper: firstly, the deployment problem of wireless Mesh router is introduced. Then the Mesh node deployment problem is abstracted and the corresponding mathematical model is established. Then, under the premise of satisfying the user coverage and connectivity requirements, an algorithm for solving the Mesh node deployment problem is proposed with the minimum network construction cost. Finally, the algorithm is simulated and analyzed on the simulation platform.
