Use this code to avoid using 2012 features:
with numbered as (
   select *, row_number() over (partition by wait_type order by snapshot_time desc) as rownum
   from monitoring.waits
)
select  w1.wait_type, w2.snapshot_time,
       w1.waiting_tasks_count – w2.waiting_tasks_count as diff_wait_count,
       w1.wait_time_ms – w2.wait_time_ms as diff_wait_time,
       1000 * datediff(second, w2.snapshot_time, w1.snapshot_time) as diff_ms
from numbered w1
join numbered w2 on w2.wait_type = w1.wait_type
where w1.rownum = 1 and w2.rownum = 2
order by diff_wait_time desc, wait_type;

Thanks for the code, do you mind helping the same with SQL SERVER 2008 or 2008 R2. As We donot have LEAD or LAG functions.
Thanks in advance.
Regards
Murali
