A spatial correlation-based wireless routing algorithm

In this paper, a wireless routing algorithm based on spatial correlation- BSC-RA was proposed. According to the spatial correlation of nodes in wireless sensor networks and the residual power of each node, this algorithm selects the cluster-heads. These cluster-head nodes broadcast their status to other nodes in the network. Each node determines to which cluster it wants to belong and join in it. Then, data acquired by nodes is aggregated by each cluster-head and transmitted to the base station. Simulate result shows that our algorithm is able to distribute energy dissipation evenly throughout the sensor nodes, effectively prolonging the lifetime of the whole network.
