Abstract : Real time wireless sensor networks are primarily constrained by the availability of energy for a long monitoring period. Either new methodologies for acquiring energy or new methodologies for efficient energy utilization have to be adopted. This paper analyzes the energy consumed by the entire network and discusses the factors and approaches used towards deriving an optimal topology which minimizes the energy consumption for the whole wireless sensor network. One application of this network, which we discuss in this paper, is detecting rainfall induced landslides. However, this can be extended to larger networks concerning almost any area of monitoring, from critical and emergency applications to long term environmental monitoring. Thus the approaches discussed here are suitable for a wide variety of environmental applications such as avalanche detection, forest fire detection, gas leakage etc.
