New Sensing Model for Wireless Sensor Networks

Authors:

Keywords: Wireless Sensor Network; sensing models; sensing coverage; energy efficiency; circular sector

Abstract:
The paper presents a new sensing model for Wireless Sensor Networks. This model, named Circular Sector Sensing Coverage, was first introduced by the authors at SENSORCOMM 09 conference. It uses circular sectors with variable central angles and radii. The purpose of the model is to minimize the energy consumption of the sensing itself, improving the energy balance of the sensor node (mote). This is especially relevant when the sensing is done remotely, by sending waves to detect intrusion or acquire data. Simulation of this model shows energy savings versus previously published schemes, suggesting the viability and the advantages of this new sensing model. However, no analytical model was yet developed. The present paper expands the scope of the previous one by adding background information about known sensing models, describing in greater details the algorithm used for simulation and by presenting new and significant simulation results. The obtained data confirms the advantages of this new sensing model. The possible implementation of such a WSN may significantly improve the energy-related performance of the WSN, allowing the development of new applications and improving the performance of existing ones.
