A Survey on Delay Constraint Scheduling in Wireless Sensor Network

Wireless sensor network concept consist sensor nodes which are developed in the specific area senses and transmit data point to point. Delay constraint is the important point in the WSN. The delay guaranteed scheduling and flow control in WSN. Delay guaranteed are important for delay sensitive applications in WSN, Where data delivery is required in a timely manner e. g packet are send if they do not received a specified period or deadline. So we defined extension of the stability region, namely the constrained stability region in which the scheduling policy stabilizes the network regarding the delay constrained. The resulting policy that guarantees delay constraints.
