WAL: An Energy Efficient Hybrid Routing Protocol in Co-operative Communication

The work focuses on the cooperative action of the heterogeneous sensor networking using water-fill algorithm. The proposed approach is based on the merits of water-fill algorithm, to maintain the signal-to-noise ratio (SNR) of the corresponding time invariant nature of the network. The proposed technique implements the algorithm by considering cluster based sensor setup and realtime transport layer constraints. Further, the results infer the energy usage comparison and the effectiveness of the proposed work with respect to sub-channel grouping for the formation of inter-cluster communication.
