Cluster-head selection algorithm of hierarchical wireless sensor networks and energy consumption are two primary problems in wireless sensor networks.

In traditional LEACH protocol,dynamic cluster head election algorithm was used in the phase of cluster head election.

Based on the practical application of network topology stability,a hybrid cluster-head selected algorithm was put forward,it contained a cluster-head selected method which was based on the barycenter(or the energy center) and a cluster-head selected method which was based on the surplus energy.

In the research of election algorithm for the mobile agent system,previous researchers mainly focus on the node-partition and partition-merge problems,and pay little attention to problems such as convergence,unlimited diffusion and function conformity of system platform.

In this paper a voting algorithm is presented to mine the optimal ingredient pattern of Chinese medicine.
