Performance Analysis on Homogeneous LEACH and EAMMH Protocols in Wireless Sensor Network

Wireless sensor network establishes a network with randomly distributed sensor devices that are connected together through some types of wireless communication networks. Such sensors are responsible for recognizing the physical or environmental conditions for multi-purpose usability and ease of deployment. This network has some limitations such as prone to network failure, and limited power and capacity of sensor devices. Several routing strategies have been originated by the researchers to improve many applications for such a network. Among the routing techniques, the clustering algorithm can increase the life span and efficiency of the network. The main feature of a cluster-based network is to minimize energy dissipation and delay of the system. This paper investigates the performance of two cluster-based routing protocols namely homogeneous Energy-Aware Multi-Hop Multi-Path Hierarchical (EAMMH), and Low-Energy Adaptive Clustering Hierarchy (LEACH) routing strategies for homogeneous nodes, sink nodes, dead nodes and other common scenarios. In this research paper, we observe that LEACH works better for small networks where there is a small number of nodes, while EAMMH works better for larger networks consisting of a large number of nodes.
