Evaluation of low energy adaptive clustering hierarchy routing protocol for wireless sensor network over high altitude plaftform

Curently, Wireless Sensor Network (WSN) is applied in many fields such as industrial plants, security, medical, as well as weather and environmental monitoring. The constraint of the use of WSN is the limited power of each sensor node, which means energy consumption efficiency is an important issue in WSN. Routing is a function in WSN which consumes a considerable amount of energy. One of the routing protocol that can increase the energy efficiency of WSN is Low Energy Adaptive Clustering Hierarchy (LEACH). In this research, energy consumption and the number of dead nodes of LEACH are evaluated using MATLAB simulation. The results show that elevation angle and number of clusters affect the energy consumption and number of dead nodes. HAP-WSN system with clustering topology will reduce energy consumption and minimize the number of dead nodes. From a set of simulations, it can be seen that energy consumption for 0° is greater than energy consumption for 10°. It can be also seen that the number of optimum cluster is 4 for both elevation angels.
