QUERY BASED SELF ORGANIZATION IN SENSOR NETWORKS

Abstract

A mobile sensor network is composed of a distributed collection of nodes, each of which is capable of sensing many types of information from the environment, including temperature; light; humidity; radiation etc. Nodes are densely deployed either inside the phenomenon or very close to it. Each node monitors its surrounding area, gathers application-specific information, and transmits the collected data to a “master” node. Also these nodes possesses self organizing capabilities e.g. starting from some compact initial configuration, the nodes in the network can spread out to collect the desired information.. This allows random deployment in inaccessible terrains or disaster relief operations .These could involve: in the air, under water, on bodies, in vehicles, and inside buildings. Another unique feature of sensor networks is their cooperative effort and onboard processing in response to queries. So instead of sending the raw data to the nodes responsible for the fusion, they use their ...
