Maximizing Throughput for Coexisting Wireless Body Area Networks (WBANs) Based on Optimal Clustering

The interference of the uplink of coexisting wireless body area networks is studied in this article. When multiple WBANs working in the same channel perform data transmission simultaneously, their uplinks will be interfered with by multiple transmission links of adjacent WBANs, which leads to data packet loss and data transmission failure. Therefore, mitigating interference and maximizing throughput are the main goals of this article. First, the graph coloring algorithm is used to analyze the interference relationship among WBANs and a mathematical model of throughput maximization is formulated. Then, the time slot reallocation algorithm is proposed to achieve node-level optimization but with high complexity. The simulation results show that the proposed scheme can achieve a good packet reception rate and throughput for coexisting WBANs.
