Evaluating the performance of reactive I-LEACH

Due to limited battery of sensor nodes, energy efficiency found to be a main constraint in WSN. Therefore the main effort has been done to enhance the network stability period and life time by minimizing the energy consumption. To achieve these objectives we propose a technique in which, an integrated scheme will work in such a way that, selection of cluster head will be made on the basis of three level decision tree. In this, residual energy is considered one of main parameter in decision tree; protection mechanism is also used to maintain the balance between clusters. The location of base station is also optimized in such a way that base station will be placed in the high node density region at runtime. Proposed technique is deliberate and executed in MATLAB. Proposed algorithm provides better results than existing clustering protocols.
