摘要:Aiming at the "hotspots" problem in heterogeneous wireless sensor networks, a routing algorithm of heterogeneous sensor network with multi-level energies based on uneven clustering was proposed. The energy heterogeneity of the nodes is fully reflected in the mechanism of cluster-heads’ election. It optimizes the competition radius of the cluster-heads according to the residual energy of the nodes. This kind of uneven clustering prolongs the lifetime of the cluster-heads with lower residual energies or near the sink nodes. In data transmission stage, the hybrid multi-hop transmission mode is adopted, and the next hop routing elections fully take account of the factors of residual energies and the distances between the nodes. The simulation results show that the introductions of uneven clustering mechanism and the optimization of competition radius of the cluster-heads significantly prolong the lifetime of the network, and improve the efficiency of data transmission.
