WSN-Wireless sensor networks are greatly in focus for the researchers. The use of WSN is foreseen for bringing massive changes in data gathering, processing and broadcasting. One of the most central design concerns in WSN is energy consumption. Hierarchical routing protocols are best acknowledged in respect to energy efficiency. Mobility based clustering (MBC) provides fruitful packet delivery rate,...
The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency,...
In WSN, sensors near the sink have to relay the data of the nodes away from the sink and as a result they drain their energy very quickly. It result in network partitioning and can significantly limit the network lifetime. This problem is termed as hotspot problem. Recently, formation of hot spot or energy hole near the sink has emerged as a critical issue for data gathering in WSN. In this paper,...
Intermittently connected wireless sensor networks (WSN) for scientific environmental monitoring raise the issue for reliable data gathering which is a key factor for having a consistent data stream as a result. First, measurements must be taken and securely saved on a node. Per node local repository for measurements is a basic mechanism for making possible to retransmit any block of data towards a...
We develop energy-efficiency data gathering schemes for wireless sensor networks (WSN), where the channel is characterized by the slow Rayleigh fading. We consider the homogeneous WSN which consists of a large number of sensor nodes equipped with the identical hardware. In the WSN, the sensor nodes are distributed randomly in a specific area. A mobile base station periodically stops by the area to...
