Improvement of counter-based broadcasting scheme for long communicating material lifetime
Résumé
The communicating material is a new paradigm of Internet of Things. It is designed to perform efficient product control and ensure an information continuum all along the product life cycle. Communicating material is obtained by scattering a huge amount of microelectronic components such as sensor nodes. However, a critical aspect of application with wireless sensor networks is nodes lifetime. The major part of energy consumption is caused by communication module, therefore judicious power management and scheduling can effectively extend operational time. In this paper, the counter based broadcasting scheme is focused on and a random delay extension is proposed to improve the wireless sensor network lifetime for communicating material application. The extension need neither additional hardware nor extra overhead, so that the strength of the original counter based algorithm is maintained. Simulation results using Castalia/OMNeT++ showed that our delay extension can reduce the number of retransmitting nodes by about 10% and hence improve the material lifetime compared with the original scheme.
