Maintenance efficient routing in wireless sensor networks [PDF]
, 2005 Communication patterns define the energy depletion profile of a wireless sensor network. In particular, routing defines which areas of the sensor field are subject to a higher traffic load. In these areas, sensor nodes deplete faster than in areas with a
