Abstract :
In this work we adopt an OFDMA like Multi-Carrier scheme for wireless sensor networks with the aim of improving the performance in the presence of intensive traffic load. To examine the MAC performance, a simple, yet accurate analytic model has been provided, validated by simulation results. We demonstrate that the proposed scheme can achieve better throughput under heavy offered traffic load, as a result of the higher bandwidth utilisation. In addition, energy efficiency and service delay performance can be significantly increased as well in this architecture.
