Review Paper On Wireless Sensor Networks

Advances in sensor technology and computer networks have enabled distributed sensor networks (DSNs) to evolve from small clusters of large sensors to large swarms of micro sensors, from fixed sensor nodes to mobile nodes, from wired communications to wireless communications, from static network topology to dynamically changing topology. To design these networks, the factors needed to be considered are the coverage area, mobility, power consumption, communication capabilities etc. In this paper a survey is given regarding the analysis of AC structure and DHC structure, flat tree and DG Network, sensor architecture design, Ad-hoc sensor networks, sensor applications and also an overview on the client/server model and Mobile-Agent Based network. Keywords— Sensor network structure, Sensor architecture design, Ad hoc wireless sensor networks, and Data processing paradigm.
