Cluster Head Optimization Strategy for Wireless Sensor Network Based on Univariate Marginal Distribution Algorithm
نویسندگان
چکیده
Low-energy adaptive clustering hierarchy (LEACH) protocol is studied. A cluster head optimization strategy for wireless sensor network (WSN) is proposed by using univariate marginal distribution algorithm (UMDA). The novel routing protocol is named UMDA_LEACH. It considers the overall situation in the effect of all cluster head nodes with the help of probabilistic model. By so doing, it improves the choice method of the cluster head nodes. Thus, to some extent it can find the optimal combination solutions for the cluster head nodes. Simulation results show that UMDA_LEACH has better performance than traditional LEACH protocol.

متن کاملEnergy-Saving in Wireless Sensor Networks Based on Optimization Sink Movement Control
A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...
