Wireless networks form heterogeneous wireless networks (HWNs) with overlapping signal coverage, and access selection is one of the key technologies of HWNs. Today, most access selection algorithms select appropriate networks mainly from the perspective of users while failing to consider resource allocation and optimize the overall transmission performance of HWNs. This paper proposes an access selection algorithm for HWNs based on optimal resource allocation by analyzing the wireless link transmission rate model, focusing on maximizing the HWN transmission rate, using the dynamic programming theory to derive the optimal value of bandwidth allocated to users. Experimental results show that the algorithm proposed in this paper can effectively improve network throughput and resource utilization and can connect users to the appropriate network according to QoS rate requirements.

基于最优资源分配的异构无线网络接入选择算法

无线网络形成具有重叠信号覆盖范围的异构无线网络（HWN），访问选择是HWN的关键技术之一。如今，大多数访问选择算法主要是从用户的角度选择合适的网络，而没有考虑资源分配和优化HWN的整体传输性能。通过分析无线链路传输速率模型，重点是最大化HWN传输速率，利用动态规划理论推导分配给用户的带宽的最优值，提出一种基于最优资源分配的HWN接入选择算法。
