Steps need to discover the neighbors in MANET

There are many ways to get/prepare a neighbor list at a node. For example,

1) at routing layer (example: you may enable hello mechanism in AODV and resolve neighbor list at a node)

2) at mac layer (like the way in which it is done in SMAC)

3) directly getting the information from GOD (this should be done only for statistical purposes – not for using that information in protocol desigh – but most people wrongly handle this information in their protocol design)
