Hi Sulaifa,

The situation in Abu Dhabi is remains difficult, but there are new school openings planned for April next year and you may benefit from this.
GEMS have just announced their relocated and expanded school http://whichschooladvisor.com/news/gems-announces-new-indian-school-in-abu-dhabi/, and Global International Indian School is expanding.  We also recently found the following information https://www.facebook.com/InternationalIndianSchoolAbuDhabi.  You will definitely find that it is only the newer schools that will be able to assist and you should definitely not wait until your arrival to contact them.   Good Luck.
