QoS management for wireless sensor networks with a mobile sink
conference paper
The problem of configuration of Wireless Sensor Networksis an interesting challenge. The objective is to find the settings, for eachsensor node, that optimise certain task-level QoS metrics. An existing configuration method is available for tree-based static networks. We ex-tend this method to support a mobile sink. First, the routing tree isadapted to the sink’s new location, after which the parameters of thenodes are optimised. Both algorithms are distributed and localised, andtherefore efficient and scalable, and are able to flexibly trade reconfigu-ration cost (time and energy) for quality to match the demands of theapplication. Various options are analysed, and evaluated in simulation.
