Energy-efficient Routing Model Based on Vector Field Theory for Large-scale Wireless Sensor Networks
Abstract: Routing design is a
key issue for large-scale wireless sensor networks (WSNs). Energy consumption
associated with allocated resources should be considered. This paper proposes
the integration of an energy-efficient model, which is based on vector field
theory, in large-scale WSNs. Source nodes in WSNs have the characteristics of
source points in a vector field, whereas sink nodes could be characterized as
gathering points. Our scheme demonstrates that we can solve a set of partial
differential equations in electrostatic theory to determine the routes that
result in energy efficiency. Thus, the routing problem in WSN for energy
efficiency becomes a typical PDE solution. Our simulation results show
significant improvement in energy consumption. Compared with the traditional
shortest path approach, the proposed model shows considerable improvement in
the lifetime of the network.
