You can scan through headers like this:

In above code I tried to find  Ipv4Header

And it is possible to access it like:


if (m_isIpv4HeaderFound)
{
NS_LOG_DEBUG("Header Found");
Callback constructor = item.tid.GetConstructor();

NS_ASSERT(!constructor.IsNull());
ObjectBase *instance = constructor();
NS_ASSERT(instance != 0);
Ipv4Header *ipv4Header = dynamic_cast (instance);
NS_ASSERT(ipv4Header != 0);
ipv4Header->Deserialize(item.current);
delete ipv4Header;
}

This is a short explanation on how I added NS-3 (version 3.6) to Eclipse (Galileo). I use first part from NS-3 Wiki

Adding Mercurial to Eclipse

First download eclipse IDE for C++ developers from http://www.eclipse.org
* Install eclipse into you operating system
* Install mercurial eclipse plugin:
- Go to help->software update
- Click on available software
- Click on add a site
- Add http://www.vectrace.com/eclipse-update/ taken from http://www.vectrace.com/mercurialeclipse/ then click on mercurialeclipse and check the box and click on install
* We suppose that you already have mercurial installed on your machine

Making a Clone of NS-3 in Eclipse

After you that you need to add the NS-3 from the repository:

Select: New -> Other, and it would be like picture below:

Eclipse mercurial after new project

Then press next. now you need to enter “Repository location URL” that is: http://code.nsnam.org/ns-3-dev

in case you want to have different versions of the NS-3 you need to define the “Clone directory name”, in the figure below I chose ns-3.7-dev

Clone the NS-3 to workspace

Now you just need to wait for the project files be cloned. then you will find a copy of the project you wanted like below:

A clone made of NS-3.7-dev in clipse

Since the folder is not know as a C++ project it is necessary to be converted to so right click on project name and select: new -> convert to a C/C++ project the rest of settings should be same as picture below:

Convert to C++ project

Configuring the Build system

We know that build system for NS-3 is Waf so we need to change the build configuration from build/make to Waf. so right click on project and select the properties then choose the “C/C++ Build”.

In the “Builder setup” choose “External Builder”

Remove the check from “Use default build command”

change “Build command” to ${workspace_loc:/ns-3.7-dev/waf}

Behaviour setting

in Behavior tab, clear both “Build on resource save (Auto save)” and “Build (Incremental build)

Behaviour setting

Now all you need to do is to push  apply and Ok. you will notice that Waf starts to build the whole project.

ACTION:	[s|r|D]: s -- sent, r -- received, D -- dropped
WHEN:	the time when the action happened
WHERE:	the node where the action happened
LAYER:	AGT -- application,
	RTR -- routing,
	LL  -- link layer (ARP is done here)
	IFQ -- outgoing packet queue
               (between link and mac layer)
	MAC -- mac,
	PHY -- physical
flags:
SEQNO:	the sequence number of the packet
TYPE:	the packet type
		cbr -- CBR data stream packet
		DSR -- DSR routing packet (control packet
                generated by routing)
		RTS -- RTS packet generated by MAC 802.11
		ARP -- link layer ARP packet
SIZE:	the size of packet at current layer, when packet goes down,
        size increases, goes up size decreases
[a b c d]:	a -- the packet duration in mac layer header
		b -- the mac address of destination
		c -- the mac address of source
		d -- the mac type of the packet body
flags:
[......]:	[
		source node ip : port_number
		destination node ip (-1 means broadcast) : port_number
		ip header ttl
		ip of next hop (0 means node 0 or broadcast)
		]

After lots of googling I got this useful blog with lots of must-to-have links for NS2, ZigBee and most of the tools to do the simulation.

We are going to have a course project for network simulation on WPAN and ZigBee and these rare resources are very handy to start with.

NS2 for IEEE 802.15.4/ZigBee LR-WPANs :

1. Simulation of IEEE 802.15./ZigBee With NS-2
2. IEEE 802.15.4 Mac Implementation in NS-2
3. Low Rate Wireless Personal Area Networks (LR-WPANs) NS-2 Platform
4. Simulative Investigation of ZigBee/802.15.4Zigbee/IEEE 802.15.4
