Relay sensor placement in wireless sensor networks
This paper addresses the following relay sensor placement problem: given the set of duty sensors in the plane and the upper bound of the transmission range, compute the minimum number of relay sensors such that the induced topology by all sensors is globally connected. This problem is motivated by practically considering the tradeoff among performance, lifetime, and cost when designing sensor n...
متن کاملproposing 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 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 کاملMultiple Sink and Relay Placement in Wireless Sensor Networks
Wireless sensor networks are subject to failures. Deployment planning should ensure that when a sink or sensor node fails, the remaining network can still be connected, and so may require placing multiple sinks and relay nodes in addition to sensors. For network performance requirements, there may also be path-length constraints for each sensor node. We propose two local search algorithms, GRAS...
متن کاملDesign and evaluation of two distributed methods for sensors placement in Wireless Sensor Networks
Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...
