Virtual Coordinate Backtracking for Void Traversal in Geographic Routing
Geographical routing protocols have several desirable features for use in ad hoc and sensor networks but are susceptible to voids and localization errors. Virtual coordinate systems are an alternative solution to geographically based routing protocols that works by overlaying a coordinate system on the sensors relative to well chosen reference points. VC is resilient to localization errors; how...
متن کاملVRAC: Virtual Raw Anchor Coordinates Routing in Sensor Networks -- Concepts and Experimental Protocol
In order to make full use of geographic routing techniques developed for large scale networks, nodes must be localized. However, localization and virtual localization techniques in sensor networks are dependent either on expensive and sometimes unavailable hardware (e.g. GPS) or on sophisticated localization calculus (e.g. triangulation) which are both error-prone and with a costly overhead. In...
متن کاملVirtual Raw Anchor Coordinates: A New Localization Paradigm
A wide range of applications in wireless sensor networks rely on the location information of the sensing nodes. However, traditional localization techniques are dependent on hardware that is sometimes unavailable (e.g. GPS), or on sophisticated virtual localization calculus which have a costly overhead. Instead of actually localizing nodes in the physical two-dimensional Euclidean space, we use...
متن کاملStateless and Delivery Guaranteed Geometric Routing on Virtual Coordinate System
Stateless geographic routing provides relatively good performance at a fixed overhead, which is typically much lower than conventional routing protocols such as AODV. However, the performance of geographic routing is impacted by physical voids, and localization errors. Accordingly, virtual coordinate systems (VCS) were proposed as an alternative approach that is resilient to localization errors...
متن کاملLogical coordinate assignment for geographic routing in wireless sensor networks
In this paper, we propose a distributed protocol to build a logical coordinate system based on the hop counts of each node to four selected landmarks, and the real location information is not needed. Our designed protocol uses the sink node as one of the landmarks and then selects three other sensor nodes near the corners of the sensor network as landmarks. The simulation results show that our ...
