A cross layer design and evaluation of IEEE 802.15.4 network with an enhanced sensor gateway: Injecting hierarchy into wireless sensor networks
09 June 2013
An enhanced 802.15.4 gateway is proposed and we perform a system comparison using a ray trace propagation model of a large office building. The gateway benefits from a 22.2dB improvement in receiver sensitivity and an optimal channel equalizer. Results show improvements over a classical sensor gateway in latency, delivery ratio and mote energy efficiency.
