Applications of wireless sensor network (WSN) often expect knowledge of the precise location of the nodes. Many different localization protocols have been proposed that allow nodes to derive their location rather than equipping them with dedicated localization hardware such as GPS receivers, which increases node costs. We provide a brief survey of the major approaches to software-based node loc...

In a wireless sensor network (WSN), node localization is key requirement for many applications. The concept of mobile anchor-based not new concept; however, the anchor nodes gains much attention with advancement in Internet Things (IoT) and electronic industry. this paper, we present range-free algorithm sensors three-dimensional (3D) networks based on flying anchors. nature also suitable vehic...

In many researches on load balancing in MultiSink WSNs, sensors usually choose the nearest sink as destination for sending data. If all sensors in this area all follow the nearest-sink strategy, sensors around nearest sink called hotspot will exhaust energy early and this sink is isolated from network. In this paper, we propose a load balancing scheme for multi-sink WSNs. A mobile anchor with d...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...

Because the received signal strength indicator (RSSI) value greatly changes, the direct use of RSSI value has more errors in the positioning process as the basis to calculate the position of anchor nodes. This paper proposes a RSSI node localization algorithm based on constraint particle swarm optimization (PSO-RSSI). In the algorithm, particle swarm optimization is used to select anchor nodes ...

This article presents a hybrid scheme for 3-D localization in mobile Wireless Multimedia Sensor Networks. For minimizing the localization error, this paper proposes efficient trajectory estimation patterns and periodic calibration of nodes’ position. Within this hybrid solution, that uses inertial measurements for location determination, the nodes’ position is periodically validated using an an...

A piece of Hovering Information is a geo-localized information residing in a highly dynamic environment such as a mobile ad hoc network. This information is attached to a geographical point, called the anchor location, and to its vicinity area, called anchor area. A piece of hovering information is responsible for keeping itself alive, available and accessible to other devices within its anchor...

In GPS-denied indoor environments, localization and tracking of people can be achieved with a mobile device such as a smartphone by processing the received signal strength (RSS) of RF signals emitted from known location beacons (anchor nodes), combined with Pedestrian Dead Reckoning (PDR) estimates of the user motion. An enhacement of this localization technique is feasible if the users themsel...

Abstract Smart Internet of Vehicles (IoV) as a promising application in Things emerges with the development fifth generation mobile communication (5G).

due to limitations in computing resources of mobile nodes, mobile ad-hoc networks (manets) are very fault-prone. so far, redundancy at different levels of the network has been considered an efficient strategy to enhance the fault-tolerance of networks. indeed, ad-hoc networks are extremely redundant; therefore, natural redundancy to fault tolerance enhancement has a great impact on the network ...
