Aodv on wsn

[omowun...@gmail.com]

Hello all,
Please i tried to implement aodv in wsn, but some SIGSEGV, Segmentation fault and from gdb debuger I got the following report:

Program received signal SIGSEGV, Segmentation fault.
0x00000000004170b5 in ns3::PeekPointer<ns3::Ipv4> (p=...) at ./ns3/ptr.h:281

Pls what do you advice that I do?

Thanks in advance.

Hi,

When you say you want to implement AODV in WSN, do you mean in the lr-wpan module?
It can not be done because lr-wpan uses IPv6 (6LowPAN) and current AODV implementation in NS-3 only works for IPv4.
That's why you get NULL pointer for the Ipv4 object.

Hello, It was ipv4 I was using in the aodv, but was just trying to implement ad-hoc in the network. Also, please do you mean that 6LoWPAN can't be simulated in ns3 yet?

Hi,

I still haven't understood how you simulate a WSN. Do you use regular WiFi or the lr-wpan module? They are different. You can use AODV with WiFi but not with lr-wpan (at the moment).
6LoWPAN can be simulated in NS-3, there is a module for that. In addition the ns-3-dev (and future releases) has coupled 6LoWPAN with lr-wpan module. Hence, you can have IPv6 networks on top of lr-wpan.

I did the aodv on regular wifi.

Then just follow the examples for AODV and WIFI in /examples/wireless and /src/aodv/examples
