[ns] 80211b send receive: differences in packet sizes?

Hi, I've two simulations, both over 802.11b networks and in both simulations, my sent packets are consistently 52Bytes larger then the receive packets?? Below is a section of out.tr for the TCP simulation? Can anyone explain the differences in sent received packet sizes? Thanks L s

? It's not any clearer why the received packet at node1 is smaller than the sent packet at node0? Richard From: Pedro Vale Estrela [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: 'Lars Lars' [EMAIL PROTECTED], ns-users@ISI.EDU Subject: Re: [ns] CBR packet size on 802.11b link Date: Mon, 18 Dec

[ns] TCP over 802.11b dropping ACKs

Hi, I've a 2-node(static) wireless link(802.11b). The tracefile is showing me that ACK packets being sent from node1 to node0 are being dropped(which is OK), however, the fourth column in the tracefile is IFQ which implies that these packets are being dropped due to the ifq. How can this be?
