Increase Sensor Network Tenure by Captive Genetic Algorithm Method

In sensor networks the nodes have limited energy, so it is critical to the save the energy of the nodes and thus the overall energy consumption of the network. This is necessary to increase the tenure of the entire network. In this paper the genetic algorithm and simulated annealing algorithms are combined to find an optimal energy efficient route for the sensor nodes towards the sink node to prolong the network tenure. The proposed method uses the nodes distance from the sink and the remaining energy of the nodes as the objective function. The simulations results show that the systems performance is further improved over the existing routing schemes.
