Effective data gathering scheme in heterogeneous energy WSN

This paper proposed an effective data gathering scheme for heterogeneous energy WSNs (EDGA). EDGA achieves a good performance in terms of lifetime by minimizing energy consumption for in-network communications and balancing the energy load. EDGA is based on weighted election probabilities of each node to become a cluster head, which can better handle the heterogeneous energy capacities. Moreover, EDGA adopt a simple but efficient method to solve the area coverage problem in a cluster range, namely intra-cluster coverage. Finally, the simulation results demonstrate that the proposed EDGA significantly outperforms LEACH, HEED in terms of network lifetime and the amount of data gathered in the heterogeneous energy network.
