In WSN, delay sensitive means minimizing the delay of event driven wireless sensor network for which events occur occasionally by using asynchronous sleep wake scheduling protocol (SWSP). SWSP can be significantly reduced the energy consumption without incurring the communication overhead the clock synchronization needed for synchronous SWSP. In WSN most of the energy consumed through when the sensor nodes are on waiting for an event to occur. SWSP is an effective mechanism to increase the lifetime of WSN. This article presents the energy consumption by the mobile sensor nodes using 802.11 media access control (MAC) and sensor media access control (SMAC) protocols and calculates total energy consumption in the network which helps to make a good balance between energy efficiency and delay. Also the investigation report is presented which explains the throughput and end to end delay of nodes and estimate the life time of sensor networks based on delay (latency). Network Simulator-2 is used for experimentation.
