Improvement of PEAR signaling in energy efficient Delay Tolerant Wireless Sensor Network

Résumé

Energy consumption is a critical point for sensor networks, which are located in remote places without access to the power grid and must harvest their own energy. The same networks may also have to use Delay Tolerant Networking technologies if they can't have a permanent connectivity. The PEAR routing algorithm was proposed to address the latter problem. In this paper, we propose an optimization of the signaling information diffusion for this particular algorithm, in order to reduce it's energy consumption. This new algorithm matches some specific characteristics that can be found in agricultural monitoring networks. Its performances have been simulated, and it multiplies network's packet efficiency by 2.77 while maintaining the same successful transmission rate as the original PEAR algorithm or Epidemic algorithm. It increase the usefulness of this algorithm in low power networks and low loaded networks.
