I tried doing the following. But I am still not able to find it.

packet_field_offset, 1, FALSE);
loc_name_length = tvb_get_ntohs(tvb, packet_field_offset);
As noted, that's not the length - the two octets before the string are
0x06 and 0x05, neither of which are the length of an 8-ASCII-character/
9-octet (including the terminating '\0') string.
Also, if the name length is 1 octet, you don't fetch it with
tvb_get_ntohs(), as that fetches *two* octets; you fetch it with
tvb_get_guint8(). If it's 2 octets, the length in the
proto_tree_add_item) call should be 2, and you should do
packet_field_offset += 2;
after fetching the name length. And the two octets before the string
aren't the length, in any case - 0x0605 is a lot more than 8 or 9.
Do you have a spec for this protocol? If so, check it to see what it
says about the location name.
