Abstract: In order to solve uneven data throughput phenomenon for wireless sensor networks under coal mine, which cause "hot spots" problem, energy-efficient uneven clustering scheme based on the energy and distribution density of cluster heads ( UCS-ED ) is proposed, which formed by many existing routing protocols used in wireless sensor networks. In the cluster heads election phase it put the energy and distribution density as two elements to join the election, form an uneven density of backbone around the Sink. Simul… Show more

“…However, there exist a few limitations in UCS as follows: (1) UCS is constrained by the assumption that the network is heterogeneous, and CHs are performed by super nodes all the time and are deployed at pre-determined locations. That is to say, it lacks universality [ 68 ]; (2) CHs are required to locate in the center of the cluster, thus a key factor, residual energy of nodes, is not considered in UCS; (3) Similar to TL-LEACH, despite that the average transmission distance is decreased in comparison with LEACH, the two-hop inter-cluster routing of UCS is still not applicable to large-range networks, because it uses only two hops for data transmission from sources to the BS, and long-distance communications need much energy consumption.…”
