Energy Based Location Optimization in Wireless Sensor Networks.

      Аннотация: Wireless sensor deployment at some strategic locations provides the best monitoring results, but the results may not reach the Base Station (BS) efficiently. It is due to the physical structural modeling. Sensor failure is expected to be quite common, due to limited energy budget. There are some sensors that deplete their energy more quickly than others, because of huge transmission. One of the fundamental requirements of Structural Health Monitoring (SHM) is sensor location optimization. According to deployment methods from civil/structural/mechanical engineering, wired sensors are usually deployed at strategic locations to achieve the best estimates of structural health status. To prolong the WSN lifetime, the energy cost of each sensor for monitoring must be carefully considered.
