Hi Hang Su,

Giorgio has explained the difference quite well. I'd just like to add
a point to it.
Essentially, MANETs are a type of mesh network, i.e. a subset of
'mesh' networks.

Mesh networking to the mesh topology, which means that each node has a
point-to-point and point-to-multipoint connectivity with other nodes,
(thereby forming a mesh). Mobile ad-hoc networking, on the other hand,
is networking among nodes that 1) form a network on the fly (ad-hoc
manner), and 2) which could also be mobile.

A mesh network can also be formed by wireless nodes that are static,
e.g. mounted on lamp posts. That said, there are currently very few
implementations of 'mesh networks' that are true MANETs.

Regards,
Pankaj.
