Comparison of LEACH and PEGASIS Hierarchical Routing Protocols in Wireless Sensor Networks

چکیده
The efficiency of wireless sensor network largely depends on the routing protocol used. Routing is a major challenge for sensor networks as it presents a trade-off between responsiveness and efficiency. Hierarchical class of routing protocols introduces a structure on the network to achieve stability, energy efficiency and scalability. There are various protocols existing in this category. In this paper, we analyse Low Energy Adaptive Clustering Hierarchy (LEACH) and Power Efficient GAthering in Sensor Information System (PEGASIS) hierarchical protocols. This work analyzes these protocols on the basis of total enery consumed, overheads, and sensors lifetime and provides a comparison of LEACH and PEGASIS with simulation results.

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

متن کاملCBERP: Cluster Based Energy Efficient Routing Protocol for Wireless Sensor Network
Since all sensor nodes in wireless sensor networks work by their own embedded batteries, if a node runs out of its battery, the sensor network cannot operate normally. In this situation we should employ the routing protocols which can consume the energy of nodes efficiently. Many protocols for energy efficient routing in sensor networks have been suggested but LEACH and PEGASIS are most well kn...
