【摘要】 综合考虑鲸鱼优化算法(WOA)在安全路由协议多维目标函数优化中的普适性和狮子算法(LA)收敛速度的高效性,建立一个优化的安全路由协议模型。不同角度分析影响路由协议安全性的信任度、能量、链路维持时间、时延、移动性等定量参数,建立相应的归一化多维目标优化函数;在该多维目标函数求解中,用WOA实现目标值的本地识别、包围与靠近,用LA算法实现区域搜索,提高算法的全局收敛速度和可靠性。通过对比仿真验证了所提算法的收敛速度和优化质量均高于其它算法。更多还原

【Abstract】 An optimized secure routing protocol(SRP) model was proposed via synthetical consideration of universality of whale optimization algorithm(WOA) in multi dimension objective function(MDOF) optimization for SRP and higher convergent efficiency of lion algorithm(LA).Several quantitative parameters,by which performance of SRP was affected,were analyzed at a different angle,such as trust degree,energy,link maintenance time,delay and mobility,based on which a corresponding normalized MDOF was established.WOA was introduced to realize local target value exploiting,encircling,and approaching,while LA was used to achieve area searching at exploration phase,in solving the MDOF model,on basis of which global convergence rate(CR) and reliability were improved.The fact that the raised algorithm or model is better than many other algorithms in CR and optimization quality,was verified through simulation comparison.更多还原
