Hi All, I think that the architecture of a mobilenode is not suitable for 802.16networks (mode PMP & Mesh). In fact , in networks such as 802.11 , when high layers have to send Data, they pass it to LL which in turn passes it to IFq and then to MAC (through PHY). When a packet is transmitted , another is sent to MAC and so on. However for 802.16 networks, the mac layer must take knowledge of the amount of data to be transmitted from higher layers in order to try to reserve enough radio ressources (minislots) to make the transmission. If we want to simulate 802.16 nets under ns-2, we must extend IFq with procedures that cuold notify the mac layer of the size of the new data it receives.Also the IFq must manage different queues corresponding to different classes of service. Am I right ? Another possible scenario, is that these queues are implemented in the 802.16 mac layer. This way all relevant tasks become easier. What is your opinion about this scenario? Could you help to make the best choice. If you have other suggestions they are welcome. Thanks a lot Ramzi TKA
