[ns] Underwater module install problem!
Dear all, I failed to install the latest underwater module under NS2. I added .o files, modified ns-default file as the instruction. I put the underwaterchannel.cc and underwaterchannel.h in mobile dir. The rest are put into mac dir. That was all about. Help me please! The following are the messages dumping. mac/underwater-phy.cc: In constructor ‘UnderwaterPhy::UnderwaterPhy()’: mac/underwater-phy.cc:44: error: no matching function for call to ‘Sleep_Timer::Sleep_Timer(UnderwaterPhy* const)’ ./mac/wireless-phy.h:58: note: candidates are: Sleep_Timer::Sleep_Timer(WirelessPhy*) ./mac/wireless-phy.h:56: note: Sleep_Timer::Sleep_Timer(const Sleep_Timer) mac/underwater-phy.cc: In member function ‘virtual void UnderwaterPhy::sendDown(Packet*)’: mac/underwater-phy.cc:221: error: ‘MIN’ was not declared in this scope make: *** [mac/underwater-phy.o] Error 1 Is that the compiler version problem? Or it's simply the bug in this program? Help please!! Thank you very much! p.s. I use ubuntu-v7.10 as my unix-like OS. Best, Jeffy Yang

[ns] Extending 802.11
Hi, I've been studying NS3. My goal is to create a 802.11s module by extending 802.11 code (recently added by Mathieu Lacage). I've been looking to NS3 architecture and in particular, the 802.11 code and supplied wifi examples: main-adhoc-wifi.cc and main-ap-wifi.cc. At this point I have some doubts that maybe someone could give some pointers: 1. How do I active tracing to see (wifi) frames and if it's possible to trace frames in pcap format. 2. How to add IP to the main-ap-wifi.cc example? Do I need just to use InternetNode instead of Node? What else should I need? 3. After analyzing Mathieu's 802.11 code, it seems that it wasn't structured in such a way that it is possible/easy to add more management frames, new beacon, etc. At first glance, it seems that I need to create a WifiMacHeader subclass and create new methods and enum types, instead of overriding methods such as: - void SetType (enum WifiMacType_e type) - enum WifiMacType_e GetType ( ) Best Regards, Nuno Rodrigues
Re: [ns] Nodes not receiving broadcast message
in my protocol code, the addr_type is NS_AF_INET
I define the port number as well
here is my broadcast code :

it works for me :)

Subject: [ns] Nodes not receiving broadcast message
I want to send a broadcast message to neighbours I'm having a problem
because the nodes are not receiving the message if I put ih-daddr() =
IP_BROADCAST;
I have tested it by putting ih-daddr() = 1; and it worked... ie. node 1 was
able to receive the message.. Below is my code for sending and also for
receiving
void ReQuest::sendREQUEST()
{
Packet* p = Packet::alloc();
struct hdr_cmn* ch = HDR_CMN(p);
struct hdr_ip* ih = HDR_IP(p);
struct hdr_MyPacket* ah = HDR_MyPacket(p);
ch-size() = IP_HDR_LEN + ah-size();
ch-addr_type() = NS_AF_NONE;
ih-daddr() = IP_BROADCAST;
ih-saddr() = index;
ah-MyPacket_type = ReQ;
Scheduler::instance().schedule(target_, p, 0.0);
}
My receive function is as follows:
void ReQuest::recv(Packet* p, Handler*)
{
struct hdr_cmn* ch = HDR_CMN(p);
struct hdr_ip* ih = HDR_IP(p);
struct hdr_MyPacket* ah = HDR_MyPacket(p);
nsaddr_t src = ih-saddr();
printf(Node %d receiving data packet from %d \n, index, src);
// processing packet
}
like i said, nodes can only receive messages if i put the IP address of the
receipient but when i use IP_BROADCAST, nothing is received...
Thank you in advance

Re: [ns] packets generated number
Not sure of built in commands but you can call in TCL like disp_count and in command function call a function and display. For this maintain array of countpkt[n] where n is no of nodes. Keep incrementing for every timer expiry of Hello + forward() function + send functions. Better have it as static variable. Regards, Maddy.

[ns] Transmitting packets without using AODV in 802.15.4
Dear friends, First of all, i would like to apologise if this is a duplicated post. I had some problems with the ns-users mailing list. I would greatly appreciate some information, or an example script, on how to sent packets without using AODV. I want to set up a CBR and directly send down packets from SSCS to MAC using 802.15.4 data primitives. I have looked in the ns FAQ and ns mailing lists but couldn't find any information on how to do it. It is mentioned that there is a TCL interface to set the transmission method in Mac802_15_4::txOption. How one can use this through a TCL script??? I am sorry for your time, if this is something trivial that I have overlooked. I await your response. Regards, George

Re: [ns] about usage fo thorughput.awk file
It has nothing to do with the USAGE of the awk file. Check the algorithm in your awk file, especially the denominators. Seems you used a 0-value counter as a denominator. good luck! -- 此致 敬礼 蔡杰
[ns] install works but make on its own produces errors on powerpc-apple-darwin8.11.0.
Hi I am having a very odd problem I am installing ns-2 on powerpc-apple-darwin8.11.0. I have not changed the makefile or any other files yet but... If I use the install /ns-2/allinone/install,v 1.31 it installs and runs fine. However soon as I go to remake it from ns-allinone-2.32/ns-2.32/Makefile it fails with the following error: * /usr/bin/ld: /Users/student3/ns-2/ns-allinone-2.32/tclcl-1.19/libtclcl.a( embedded-tclobj.o) malformed object, illegal reference for -dynamic code (reference to a coalesced section (__TEXT,__textcoal_nt) from section (__TEXT,__eh_frame) relocation entry (8)) collect2: ld returned 1 exit status make: *** [ns] Error 1* If I do a make again it produces the same error. if i then do a *make clean *then a *make *it produces the same error again. If I do a *make distclean* then a *./configure --with-otcl=../otcl-1.13/ --with-tclcl=../tclcl-1.19/* (this what I think the install is doing) then make it still produces the same error. Please any ideas? I'm going mad! Thank you Mark
