  Abstract

This paper addresses the collision resolution issue to enhance the performance of wireless sensor networks based on IEEE 802.15.4 slotted CSMA/CA. Some solutions in existing work try to solve this issue by adjusting Backoff Exponent (BE) value or Backoff Period (BP). In contrast to the existing solutions, the proposed scheme in this paper aims at providing high system throughput, but also achieving efficient energy consumption of sensor nodes by using Preamble Address (PA). For this, in the proposed scheme, only one sensor node begins data packet transmission by performing PA contention phase with other nodes before sending each data packet. Our simulation results show that the proposed scheme outperforms existing algorithms in terms of energy consumption and throughput.
