UWB无线通信网络是未来无线通信最具潜力的技术之一。选择高速稳定的路径进行通信十分重要。文章在常用位置辅助(LAR)路由算法的基础上,提出了一种新的位置辅助路由算法(LASSR)。该算法在利用UWB技术精确定位功能的基础上,引入信号稳定因子,并以此作为路径选择的依据,从而增强了所选择路径的稳定性,减少了因为路径失效带来的重新路由次数。仿真结果表明,LASSR算法比LAR算法具有更好的性能。
UWB wireless communication network is one of the most promising technologies for future wireless communications. It is important to choose a high-speed, stable path for communication. Based on the commonly used Location Assisted (LAR) routing algorithm, a new location-assisted routing algorithm (LASSR) is proposed. Based on the UWB precise positioning function, this algorithm introduces the signal stability factor and uses it as the basis of path selection, thus enhancing the stability of the selected path and reducing the number of rerouting due to path failure. Simulation results show that LASSR algorithm has better performance than LAR algorithm.
