Coordinated Workload Scheduling in Hierarchical Sensor Networks for Data Fusion Applications

To minimize the execution time of a sensing task over a multi-hop hierarchical sensor network,we present a coordinated scheduling method following the divisible load scheduling paradigm.The proposed scheduling strategy builds on eliminating transmission collisions and idle gaps between two successive data transmissions.We consider a sensor network consisting of several clusters.In a cluster,after related raw data measured by source nodes are collected at the fusion node, in-network data aggregation is furth...
