The cluster head is selected by the random number generated by nodes in the hierarchical routing protocol which is implementing Low Energy Adaptive Clustering Hierarchy (LEACH). As a result, the cluster head may be chosen randomly and be

子群优化算法中,粒子群由多个粒子组成,每个粒子的位置代表优化问题在D维搜索空间中潜在的解。根据各自的位置,每个粒子用一个速度来决定其飞行的方向和距离,然后通过优化函数计算出一个适应度函数值(fitness)。-Subgroup of particle swarm optimization algorithm is composed by a number of particles, each particle' s position represents to optimize the p
