Energy Aware Algorithms for Wireless Sensor Networks

The study of Wireless Sensor Network is focused mainly on increasing the values of two main parameters like network lifetime and information reliability. All the algorithms and routing techniques applied on such networks try on their best effort to improve the performance and to have as result the most convenient values of both parameters. Lifetime and reliability are crucial in all kind of WSN application but especially in underwater as the case of this work. The main contribution of the paper consists in studying the behavior of the network while varying the different parameters like node distance from each other, node selection criteria for the different node roles in the network, definition of network lifetime duration, etc. Simulations show that due to these parameters the network decides itself when to stop functioning. The network lifetime becomes flexible based on the specific requirements of user applications.
