Relevance Precise Protocol Structural Design for Wireless Sensor Networks

Wireless Sensor Networks are networks composed of large number of tiny, batter dependent sensor nodes comprising of restricted on-board storage, processing and radio potentials. Nodes sense the information from the surroundings around them and forward it to the central node which is labelled as Base Station. In view of the fact that the nodes consume lots of energy for this processing of data, the architectural protocols and algorithms has to be attentive to provide an efficient routing. Because of efficient routing, the network lifetime can be raised. In general, the real life purposes depend upon the concept of heterogeneity despite homogeneity. In his paper, a protocol is proposed which works upon the implementation of heterogeneous sensors which are differ in the energies of each other. The first simulation is done by using LEACH (Low Energy Adaptive Clustering Hierarchy) which is entirely a homogeneous energy protocol. Subsequently, the second simulation comes out to be more effective which uses H-LEACH (Heterogeneous LEACH). This proposed H-LEACH uses the heterogeneous sensors which considerably reduces the energy consumption and prolong the lifetime of network.
