Energy Efficient A-Leach Routing Protocol

چکیده
Leach was the first most Routing Protocol used clustering concept in wireless sensor networks. Leach algorithmre-clustering process play vital role to gather data in cycles known as round. During each round a specific percentage of total nodes are elected as cluster heads (CHs). Each node get chance to become CH according to their probability in particular round. It is possible that not a single node is selected as CHs and few of nodes have to act as forced CH by ignoring residual energy, nodes location, and other significant parameter, which is the main reason for CH failure. Therefore to overcome this limitation Energy Efficient A-Leach Routing protocol is proposed which uses the forward/backward multi hop path approaches to increase the lifetime of WSNs and allow CHs to transmit their gathered data to Base Station (BS).

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 کاملLeach Routing Algorithm Optimization through Imperialist Approach
Routing is an important challenge in WSN due to the presence of hundreds or thousands of sensor nodes. Low Energy Adaptive Clustering Hierarchy (LEACH) is a hierarchical routing and data dissemination protocol. LEACH divides a network domain into several sub-domains that are called clusters. Non-uniformity of cluster distribution and CHs selection without considering the positions of other sens...

Designing a protocol stack for wireless sensor network (WSN) is a challenging task due to energy, computational, communication and storage constraints. Energy spent for communication between sensor nodes dominates the energy spent for the computation [1]. Multi-hop short range communication between wireless sensor nodes is energy efficient compared to single-hop long range communication. Hierar...
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...

Wireless sensor network (WSN) requires robust and energy efficient communication protocols to minimise the energy consumption as much as possible. However, the lifetime of sensor network reduces due to the adverse impacts caused by channel fading and interference in WSN. A cluster based cooperative multi input multi output (MIMO) routing scheme is proposed as a solution for this problem. Two MI...
متن کاملA Clustering Method for Energy Efficient Routing in Wireless Sensor Networks
Low-Energy Adaptive Clustering Hierarchy (LEACH) is one of the most popular distributed cluster-based routing protocols in wireless sensor networks. Clustering algorithm of the LEACH is simple but offers no guarantee about even distribution of cluster heads over the network. And it assumes that each cluster head transmits data to sink over a single hop. In this paper, we propose a new method fo...
