    Tree-Forming Schemes for Overload Control in Wireless Sensor Networks

    Node placement in Wireless Sensor Networks (WSNs) is frequently redundant and massive. Massive and dense deployments require efficient and effective, topology control algorithms in order to reduce the number of active nodes and ease the transportation of data from sources to sinks. Tree-forming is a common strategy in topology control...

    Source-Based Routing Trees for Efficient Congestion Control in Wireless Sensor Networks

    Placement of nodes in Wireless Sensor Network (WSNs) is often massive and random. Topology control algorithms focus in lowering the initial network topology, by reducing active nodes and links, thus saving resources and increasing network lifetime. Currently, most algorithms and schemes in WSNs, construct shared, core-based trees, with the sink...
