Abstract
In this paper, the capacity criteria have been proposed in order to select a cooperative relay node in WSNs, under the environment where direct path has a poor link gain. This process may ensure the efficiency improvement of signal transfer between source and destination and reduction of energy consumption as well. Two criteria are incorporated to select a cooperative relay node. Firstly, calculate the energy gain ratio between the relay path and the direct path. Secondly, investigate the effects of relay node's usage in WSNs through the simulation in terms of energy consumption. In the simulation, the relationship between energy consumption and direct path gain, uniformly generated in the certain range and its positive effects have been identified.
