Design of an Unstructured and Free Geo-Coordinates Information Brokerage System for Sensor Networks using Directional Random Walks

The main problem studied in this paper is how to design an efficient method for information brokerage in sensor networks that do not use an overlay layer to organize the network and when geo-coordinates are not provided. We present a method for the solution of this problem using Directional Random Walks (DRWs) which main purpose is to construct a straight path of relaying nodes in the network.
