Distributed Positioning Technique in Wireless Ad Hoc Sensor Networks
To support processing and collaboration, every node in the network needs to know the identity and location of its neighbors. This can be easily obtained in a planned network and quite hard in ad hoe networks whose topology is constructed and updated in real time. Selflocation using GPS may not be feasible but an effective distributed positioning algorithm is to be used. The proposed technique i...
متن کاملRobust Positioning Algorithms for Distributed Ad-Hoc Wireless Sensor Networks
A distributed algorithm for determining the positions of nodes in an ad-hoc, wireless sensor network is explained in detail. Details regarding the implementation of such an algorithm are also discussed. Experimentation is performed on networks containing 400 nodes randomly placed within a square area, and resulting error magnitudes are represented as percentages of each node’s radio range. In s...

Key attributes of types of networked systems are the severely computational and energy resources, and an rational environment. This paper is a study of nication security aspects of these networks. imitations and specific architecture of sensor all for customized security mechanism...
متن کاملPositioning in mobile Ad-Hoc Networks
This Semester Thesis gives in a first chapter a short introduction to mobile ad-hoc networks with its applications, to the Bluetooth technology and to positioning in adhoc networks. In the second part, the Receiver Signal Strength Indicator (RSSI) is examined and analyzed, if this value can additionally be used for measuring a distance between two nodes. Unfortunately the result shows, that the...
متن کاملMobility-enhanced positioning in ad hoc networks
This paper discusses and investigates the effects of mobility on positioning of wireless ad hoc networks. We present a Mobility-enhanced Ad hoc Positioning (MAP) scheme, where we leverage on the mobility of nodes within the network. The scheme uses the hop counts information from fixed reference nodes to perform positioning and improves accuracy by using mobile nodes to “bridge” gaps within nei...
