Dear Sidney, I have been trying to install ns-2.27 to my machine runs under vista home. Even I have downloaded all the packages of cygwin, I could not install ns-2.27.

However, during the installation it gives a such message tclcl-1.15 make failed!, Exiting. I chechked all my packages, whether I have installed or not, using the cygwin setup and choosing view section, there does not appear any package to install. Do you have any opinion or suggestion? best hakki Sidney Doria wrote: I'm using cygwin 1.5.24 and ns-2 2.31 on Vista Home Premium.

[ns] How to Drop Packets From a Particular Sender
Hi to all.. i am using ns-2.33, here in my work i have to drop packets from a particular sender, i am planing to drop packets depending on the sender node_id please help me regarding this.. by Muralikrishna Gaddam (muralikrishn...@gmail.com)
Re: [ns] How to send a message from one node to another node (i.e. to send an integer value)
Gaddam, this is the FIRST BASIC step when you learning NS-2. You can find lots of information about this, here: - asking google; - reading NS-2 manual; - tutorials in the NS-2 wiki; - on the book Introduction to Network Simulator NS-2. But we know how difficult are the first steps! So, this tutorial can help with scripts (in OTcl) or how to code (in C++) to send and receive packets in NS-2: http://masimum.inf.um.es/nsrt-howto/pdf/nsrt-howto.pdf That tutorial is for WIRELESS networks. If you want for Wired networks, I suggest you the Marc Greiss's tutorial (Section IV): http://www.isi.edu/nsnam/ns/tutorial/ Sidney Doria UFCG / BRAZIL 2009/3/13 muralikrishna g muralikrishn...@gmail.com: hi to all.. i am using ns-2.33, here i have to send a message (i.e. to send an integer value) from one node to another node, is it possible in tcl script itself.. or i have to go for c++ please help me regarding this, by Muralikrishna Gaddam (muralikrishn...@gmail.com) -- Sidney Doria Redes ad hoc móveis Doutorado em Computação UFCG Brasil Nessa jornada, o conhecimento será o seu escudo...

Re: [ns] How to Drop Packets From a Particular Sender
Hi! Wouldn't it be kind of dangerous to drop the packet using the first method described? The packet would jsut disappear and the logs would not be consistent. I would recommend using the latter method drop(p) instead. This makes the logging consistent and almost all objects I've come across where I would like to drop packets have been Connector objects.

Re: [ns] Neighbor List
I think you can look at channel.cc to find the list of neighbours because whenever a new mobile node is entering the channel its keep information in the list. Otherwise if you trying to find out the neighbouring BS then you can check it out from the mip-reg.cc file.

Since past few days, I have been trying to set the range by the setting the value of radius variable of a particular node. This is what radius variable does according to NS Manual: $mobilenode radius r The radius r denotes the node’s range. All mobilenodes that fall within the circle of radius r with the node at its center are considered as neighbours. This info is typically used by the gridkeeper.. But, today I found out that this is not affecting the way the traffic is sent, i.e., the range is still 250m, the default value. Please help me as to how can I set the range of the nodes. This is is very much imperative for my project. Please help. -- Regards, Mayank Daga Senior Undergraduate Student, Department of Information Technology, National Institute of Technology, Durgapur, India

Re: [ns] How to Drop Packets From a Particular Sender
Hi Mats, I agree with you. In fact, function drop(p) will check whether the packet is in used before dropping it. But the function drop(p) only exists for an NsObject. Objects not derived from class NsObject may not define this function. If you guys would like to use Packet::free(p), you are responsible for consistency check. Failing to do so may result in errors like segmentation fault. Best, Teerawat On 3/13/2009, Mats Folke mats.fo...@ericsson.com wrote: Hi!
