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 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 کاملRelay node placement to heal partitioned wireless sensor networks
The wireless sensor networks deployed in hostile environments suffer from a high rate of node failures. Such failures may convert a fully-connected sensor network into multiple disjoint sub-networks, leading to the network partition problem. The placement of relay nodes is the only way to restore the lost connectivity because these devices, compared to the sensor nodes, have a higher energy bac...
متن کاملRelay 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 کاملOptimal Node Placement in Multiple Relay Wireless Networks
This thesis explores the optimal node placement for linear Gaussian multiple relay networks of an arbitrary size and with one source-destination pair. Consider the model that signal attenuation grows in magnitude as 1 dδ with distance d in the low attenuation regime (path loss exponent δ < 3/2). Under the condition that the minimum achievable rate from source to destination is maintained, we de...
