Building an early warning system which detects wild animals near the road/rail with the help of wireless sensor networks and alerts passing vehicles of possible animal crossing.

About This is an event-driven simulation of dynamic bandwidth allocation (DBA) in Fiber-To-The-Room (FTTR) network, where the External PON is a 50 Gbps Gigabit Passive Optical Network (50G-PON) with split-ratio 1:16 and the Internal PON is a 10G-PON with split-ratio 1:8. Note that This is an abstract implementation of the ITU-T standard G-PON MAC.
