proposing a novel algorithm for fault-tolerant relay node placement in wireless sensor networks
wireless sensor networks are composed of hundreds or thousands of small nodes called sensor that work together and are associated with a specific task or tasks to do. each of these nodes includes sensor, processor, communication components, a small memory and a source of energy. it is expected that wireless sensor networks will be used widely in many applications in near future. scalability and...
متن کاملPartial Fault-Tolerant Relay Node Placement in Heterogeneous Wireless Sensor Networks
Existing work on placing additional relay nodes in wireless sensor networks to improve network connectivity typically assumes homogeneous wireless sensor nodes with an identical transmission radius. In compare, this paper addresses the problem of deploying relay nodes to provide fault tolerance with higher network connectivity in heterogeneous wireless sensor networks, where sensor nodes have d...
متن کاملOptimal Node Placement in Wireless Underground Sensor Networks
Wireless Underground Sensor Networks (WUSNs) are active and emerging area of application of Wireless Sensor Networks (WSNs), whereby sensor nodes are located under the ground environment. The communication between the nodes is done underground, with the aim of sensing events to transmit the sensed events to the sink, which is normally in the terrestrial environment. The most challenging issue i...
متن کاملRelay Node Placement in Wireless Sensor Networks: A Survey
Recently, wireless sensor networks (WSNs) have been immensely used in many real-life outlines, and have become very important. These sensors sense some physical phenomenon and then gathered information is processed. Sensor nodes may be affected from a huge distortion in severe surroundings, that causes the network to get split into multiple disjoint segments. Now to join these segments (in WSNs...
متن کاملEfficient Node Placement for Congestion Control in Wireless Sensor Networks
Wireless sensor nodes are small, embedded computing devices that interface with sensors/ actuators and communicate using short-range wireless transmitters. Such nodes act autonomously, but cooperatively to form a logical network, in which data packets are routed hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless Sensor Network (WSN) comprises of a potential...
