Hi all,
We intend to implement channel hopping using ns2 simulator. Has anyone tried
to implement hopping in ns2?
Our approach:
We found that each channel (class WirelessChannel) keeps a linked list of all
nodes listening on that channel. For a mobilenode to hop we wrote code to
dynamically add and remove the node from this list. However, on running ns
we get a segmentation fault. The code we wrote looks something like:
MobileNode* n = node that hops;
WirelessChannel new = next channel to hop to;
WirelessChannel current = current channel of node n;
new.addNodeToList(n);
current.removeNodeFromList(n);
It would be great of someone share thier experience in implementing channel
hopping in ns2.
I cannot help with the channel hopping. But to find problems with linked
lists etc. in the C++ part of the code it is always a very good idea to
run ns-2 using valgrind. Simulations will use a lot more time to run,
but every strange or wrong memory access will be recognized.
