Imposing the constraint of timely delivery on usual messages is referred as time-constrained messages. The utility of such messages depends upon the time at which they arrive at their destination. Due to contention among randomly arriving messages at each node/link and multi-hops between the source and destination that a message must travel, it is difficult to guarantee the timely delivery of such messages. In case of faulty links or node, it is likely impossible for messages to reach at required destination in time.
