Wireless Sensor Network(WSN), which is a new network-technology, can be widelyapplied in agriculture, industry, city management, rescue and relief work. Nowadays, it isnike trainers becoming a hot topic in wireless communication researches, among which the sensorself-localization is a fundamental and crucial issue for WSN. Accurate self-localizationcapabilityishighlydesirablein wirelesssensornetwork.Firstly, the thesis gives a brief introduction of the chi hair straightener localization algorithms in WSN.Secondly, the theory of localization Lacoste Polo Shirts algorithms, which includes the basic principle,classification and the performance evaluation of localization algorithm is introduced. Thisthesis studies thetypical localizationalgorithms Buy cheap nike shoes infourclasses.Becausethenode localizationis an optimization problem in nature, the four optimization algorithm-based localizationalgorithms, which are Genetic Algorithm based localization(GAL), Simulated cheap evening dresses Annealingbased localization(SAL), Evolutionary Strategies based localization(LESS) and DifferentialEvolution based localization(RCDE) are focused on. The pseudo-code or procedure of eachlocalization scheme is introduced and analyzed in details.
