Awake/Sleep Mechanism Using LEACH Protocol in WSN - An Energy Efficient Approach

The hierarchical clustering, like the LEACH protocol, utilizes the Cluster Head system for collecting and aggregating and transmitting data. The Cluster Heads are chosen in arbitrary after each round based on the information transmitted by the sensor node. Cluster Heads or the non-Cluster Head nodes which are at a greater distance from the Base Station will consume extra energy in sending information from a similar distance. The ASLEEP mechanism is induced in the traditional LEACH protocol. Accordingly, the new methodology expands the lifetime of the network to a greater extent. The time of talk interval should be set with the base time expected to effectively get the whole message from all the sensor nodes. The sleep mechanism in LEACH consequently changes the sensor nodes exercises, in this way accomplishing low power utilization and low message inactivity. This drags out the network's lifetime by a component that directly relies upon the level of redundancy. In any event, during the low duty cycle, the sleep time of adjoining nodes times are coordinated.
