WSNs energy hole alleviate algorithm based on dual cluster grid-based scheduling is designed

primary and secondary cluster head grid clustering algorithm is designed to form grid cells;nodes are identified according to nodes ID and grid ID;and the computer math model of centre point of grid cell is constructed to determine the cluster head of each cell grid for scheduling the node in cell;as well as data scheduling transmission structure with primary-secondary-neighboring cluster heads is constructed to effectively disperse load of nodes

and theory analysis is carried out on performance of this scheme.Simulation results show that compared with others mechanism

this algorithm effectively avoid energy hole

and node duration time is longest under the conditions of non-uniformly distributed nodes

remarkably eliminate‘funnel effect’.
