Hierarchical Cuckoo Search-based routing in Wireless Sensor Networks

In this paper, we present a hierarchical routing algorithm based on a bio-inspired heuristic named Cuckoo Search (CS) approach. In our proposed scheme, the network area is divided into a logical virtual grid. Nodes are deployed randomly and organized as static clusters where each cell represents one cluster. After the cluster heads are elected, data is collected, aggregated and forwarded to the base station using the cuckoo search approach. Extensive simulations showed the effectiveness of our data dissemination mechanism. They confirm that our proposed scheme outperforms other conventional existing techniques such as LEACH and M-GEAR in terms of energy saving.
