Wireless Sensor Network (WSN) comprises a large number of tiny sensor nodes. These nodes are intelligent of sensing and monitoring the environmental or physical condition like temperature, sound, pressure, motion, etc. and communicating with other nodes. Sensor nodes in WSN have limited power and energy constraint hence it becomes necessary to efficiently use these resources. Energy consumption is...
Extended network lifetime and load balancing are important requirements for many WSN applications. There are many clustering routing schemes for homogeneous proactive and reactive WSNs but they suffer from the problem of uneven load distribution and back transmission. This paper presents an energy efficient load balanced clustering scheme with away cluster head (ACH) scheme and free association mechanism...
This paper proposes a simple Wireless Sensor Network (WSN)-based water level and water quality monitoring system for fish ponds. The proposed architecture uses RGB color sensors and provides a low cost and real-time monitoring system to grow healthy fish and avoid anomalies such as overflow or low water level and the death or disease of fishes for unhealthy water (e.g., rise of acid level due to the...
Recently many Wireless Sensor Network (WSN)-based agriculture monitoring systems have been implemented mostly for developed countries. WSN in these monitoring systems uses tree topology and multi-hop dynamic flooding routing protocol that are not energy efficient and has a single point of failure. Though some protocols use zone-based routing they consider that a large number of sensors are deployed...
Integration of sensors, embedded operating systems, wireless networking technology, wireless sensor networks, is a new information gathering and processing technologies, in environmental monitoring has a very good application and advantages. This paper introduced a method model based on ZigBee-technology. Depending on specific situation in environment, LEACH communication protocol was chosen. The...
LEACH (Low Energy Adaptive Clustering Hierarchy) is a clustering-based protocol that utilizes randomized rotation of the cluster-heads to evenly distribute the energy load among the sensor nodes in the network. This classical protocol has been widely used in wireless sensor network (WSN). However, it has the disadvantage of irrationality of electing cluster-head and of unbalanced energy consumption...
The design of routing protocol gradually becomes the research core of network layer in the various research areas of wireless sensor networks. This article starts from analyzes the wireless sensor networks architecture, it mainly researches the routing protocol LEACH for wireless sensor network, as directly sends data between the cluster node and the base station, the cluster node far away from the...
