Abstract:
Networking system refers to the technique which allows users to share the information and resources. It requires robust wireless communication protocols that are energy efficient and provides low latency. In wireless sensor network, energy efficiency is an important issue to create a healthy communication system. The applications of WSN covers a wide range and provides remote monitoring using networked micro-sensors. Sometimes while requiring high performance from the network, they suffer from resource constraints that do not appear in more traditional wired computing environments. Nodes which contain limited bandwidth are mainly battery operated, which is considered as limited available energy. Cluster formation process helps to ensure sometimes hierarchical structure where the CH nodes form the higher level and the cluster-member nodes form the lower level. For dealing with the harsh environment, an application specific protocol architecture is comparatively more preferable than the traditional layered approach. LEACH (Low-Energy Adaptive Clustering Hierarchy) is an architecture for remote micro-sensor networks that combines the ideas of energy-efficient cluster-based routing and media access together with application-specific data aggregation to achieve good performance in terms of system lifetime. In order to prolong the life span of the entire network, this work provides a simulation of ‘Balanced LEACH’ protocol with a second selection of the cluster heads each round to keep the constant and near-optimal cluster heads number. Main objective of this work is about proposing a simulation which can ensure a lifetime efficient networking or data transmission. All the simulations are performed using MATLAB. For reducing information loss for the data aggregation property of LEACH-B a simulation which has modified the “LEACH-B” has been proposed to ensure optimization and more robustness. Regarding clustering algorithm, MATLAB coding shows the rate of change of energy of nodes which results the curves of change of number of nodes with respect to the change of rounds. Separate MATLAB curves have been executed for normal and advanced nodes using LEACH-B, CogLEACH and WST-LEACH protocol. In the simulation which has been shown, the timing of the first node dying in the case of modified LEACH-B protocol is 4.37% more than that of LEACH-B protocol. The MATLAB curves also show that the energy lowering rate of Modified LEACH-B which performs almost 2 times better than that of LEACH-B protocol.
