There is advantage of fixed physical location for airfield lighting in airport lamp monitoring using WSN, but some lamps location is irregular, which caused large consumption of the cluster head nodes in this logic region, early death, the formation of voids during transmission, and these voids undermined the entire wireless sensor networks energy balance, reduced the WSN lifetime. To solve these...
The increased interest in use and area of Wireless sensor networks(WSN) have led to designing of many new routing protocols in which energy awareness is of great consideration. In this paper LEACH and its two variants LEACH-E, LEACH-EX is analyzed by simulation. Their performance is compared by varying parameters such as initial energy, probability of CH node election and size of the packet.
Recently, special types of routing protocols are designed for sensor networks. Almost all of these routing protocols have considered the energy efficiency as the ultimate objective in order to maximize the lifetime of the whole network. The different types of routing protocols available in WSN are data centric, hierarchical, and location-based and on demand routing protocols. Low-Energy Adaptive Clustering...
Wireless sensor networks(WSN) deploy a large number of sensor nodes in the monitoring region, collecting information which is sent to the target users by wireless means after simple treatment. As the wireless sensor nodes are usually deployed in inaccessible or high-risk areas and are in large numbers, replacing batteries becomes very difficult. The nodes are usually one-time battery-powered so there...
In the existing clustering protocol, cluster heads (CHs) usually transmit data to Sink directly with long-distance transmission and huge energy consumption. To solve this problem, an inter-cluster gateway-based energy-efficient routing protocol (IGER) is proposed in this paper. It makes cluster heads evenly distributed, chooses appropriate nodes to be gateways for inter-cluster communication to share...
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...
