Routing protocol for wireless sensor networks based on schema theory
Aiming at the characteristic of wireless sensor network routes in some special situations that some nodes must be present in the paths, a protocol for constructing optimal paths quickly based on schema theory for wireless sensor networks is provided. To improve the efficiency of data translation, the genetic algorithm schema theory is applied to create the routing protocol of wireless sensor networks. Fitness functions with the weights of communication energies, consumptions and residual energies are established. In the process of chromosomes coding, selection, crossover and mutation operators, the individuals with schemata are ensured to increase in certain heredity probability in the heredity process. The approximate optimal paths for wireless sensor networks are approximated utilizing the information resources and strong calculating function of base stations. Simulation results show that compared with the flooding model and ZHOU model, the routing protocol for wireless sensor networks based on schema theory can prolong the network lifetime and improve the network performances.
