After 6LowPAN stack. Every node can have the different internet IPv6 address. So,

  1. Is 6LOWPAN stack is present in GATEWAY or sensor mote as well?

  2. In a case of sensor mote, is a GATEWAY required? Can't 6LOWPAN enable sensor to directly connect to IPv6 Router?

Correct me if I am missing some fact or data.

In any case, a 6LoWPAN enabled Sensor Network needs a Gateway to interact with an end user who might be using a standard 802.11 WLAN or a 802.3 Ethernet based network.

The Gateway needs to translate the 6LoWPAN enabled IPv6 addresses into addresses that standard networks can understand and communicate. For instance, if a node with 6LoWPAN enabled on it with Header Compression has Address ::1 there needs to be some defined way to know how to access this sensor node over a connected network. For that you need a gateway which does translation for you.

Have a look into 6lbr by CETIC for some more implementation specific example.
