摘要：

An energy-balanced unequal clustering algorithm is proposed to solve the hotspot problem caused by long ribbon topology of mine roadway, in which the cluster heads close to the sink which has heavy burden leading to failure. A new threshold formula is constructed to elect the candidate cluster heads. Candidate cluster heads determine the cluster heads by certain campaign radius. After a reasonable partition, the clusters closer to the sink node have fewer nodes than those farther away from the sink node to balance the energy consumption; the hybrid communication mode within the cluster is adopted for the load balancing; for the data-forwarding between the cluster heads, the lowest energy consumption mechanism is proposed to select the next hop. Simulation results show that this protocol can balance energy consumption effectively to extend the network life cycle.
