A multiple criteria algorithm for planning the itinerary of mobile sink in wireless sensor networks
The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...
متن کاملCalculation of an Optimum Mobile Sink Path in a Wireless Sensor Network
A wireless sensor network (WSN) is a collection of spatially distributed, resourceconstrained sensor nodes, deployed within an application area, to monitor a specific event or set of events. These sensor nodes are standalone devices without access to a continuous energy source and are located either within or close to the phenomena they are observing. The nodes communicate with one or more cent...
متن کامل3D Path Planning Algorithm for Mobile Anchor-Assisted Positioning in Wireless Sensor Networks
Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...
متن کاملProlonging Network Lifetime in Wireless Sensor Networks With Path-Constrained Mobile Sink
Many studies in recent years have considered the use of mobile sinks (MS) for data gathering in wireless sensor networks (WSN), so as to reduce the need for data forwarding among the sensor nodes (SN) and thereby prolong the network lifetime. Moreover, in practice, often the MS tour length has to be kept below a threshold, usually due to timeliness constraints on the sensors data (delay-critica...
متن کاملDynamic Trajectory Design of Mobile Sink in Wireless Sensor Network
This paper proposes an algorithm to determine a mobile sink trajectory to cover the entire target area in a timely manner and dissemination of data with lesser delay. The proposed algorithm is based on Hilbert Space Filling Curve algorithm with dynamic control of graph order according to network density. The simulation results show that by overlaying smaller order curve on greater order curve i...
