Recent years showed a wide range of applications in Wireless Sensor Networks (WSN). For a WSN, Topology Control is crucial to obtain an energy efficient network without affecting the connectivity and other properties. In this paper the sequence of strategies carried out to obtain a better scheme for a topology control in terms of energy is discussed. The results showed the effectiveness of the different approaches proposed. The future works discussed also gives a wider vision on the probabilities of the various schemas for the forthcoming years.
