A Novel Method for Service Differentiation in IEEE 802.15.4 : Priority Jamming
Keywords:CSMA/CA, QoS, priority jamming, service differentiation, IEEE 802.15.4
IEEE 802.15.4 employs carrier sense multiple access with collision avoidanceÂ (CSMA/CA), which is known to have difficulty for supporting quality of serviceÂ (QoS). In this paper, a new priority scheme called priority jamming (PJ) is proposedÂ for service differentiation for IEEE 802.15.4. The main idea of the proposed schemeÂ is deferring the low priority packet transmission for the high priority packet. ClearÂ channel assessment of IEEE 802.15.4 is modified to support the proposed PJ. The efficiencyÂ of the proposed scheme is validated by comparing the delay, throughput, andÂ energy-per-bit with those of standard CSMA/CA. Simulations results showed thatÂ PJ improves the delay and throughput simultaneously while maintaining marginalÂ difference in energy efficiency.
