ABSTRACT

The communications capability of devices and continuous transparent information routes are indispensable components of future oriented automation concepts. Communication is increasing rapidly in industrial environment even at field level. In any industry the process can be realized through sensors and can be controlled through actuators. The process is monitored on the central control room by getting signals through a pair of wires from each field device in Distributed Control Systems (DCS). But the latest trend is elimination of wires i.e., wireless networks.Wireless sensor networks - networks of small devices equipped with sensors, microprocessor and wireless communication interfaces. In 1994, Ericsson Mobile communications, the global telecommunication company based in Sweden, initiated a study to investigate, the feasibility of a low power, low cost ratio interface, and to find a way to eliminate cables between devices. Finally, the engineers at the Ericsson named the new wireless technology as "Blue tooth" to honor the 10th century king if Denmark, Harald Blue tooth (940 to 985 A.D).The goals of blue tooth are unification and harmony as well, specifically enabling different devices to communicate through a commonly accepted standard for wireless connectivity.

LITERATURE SURVEY The field of smart sensor networks based on wireless link has gained a significant amount of momentum in recent years.1. Professor A.J. Sammes, BSc, MPhil, PhD. have proposed the concept of wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks. In wireless sensor networks, communication takes place with the help of spatially distributed autonomous sensor nodes equipped to sense specific information. wireless sensor networks, especially the ones that have gained much popularity in the recent years, are, typically, ad hoc in nature and they inherit many characteristics/features of wireless adhoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-configure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up wireless sensor networks fast in situations where there is no existing network setup or in times when setting up a fixed infrastructure network is considered infeasible, for example, in times of emergency or during relief operations. wireless sensor networks find a variety of applications in both the ;ilitary and the civilian population worldwide such as in cases of enemy intrusion in the battlefield, object tracking, habitat monitoring, patient monitoring, fire detection, and so on. This paper attempts to provide a comprehensive guide on fundamental concepts.2. Roberto Verdone is full Professor at the University of Bologna, Italy. He has been performing research in wireless networks since 1991.Hehave proposed a model for the sensor networks based on wireless technology. Wireless sensor networks have been widely studied in the past years, and the scientific literature reports many outcomes that make them applicable for some applications. For some others, research still needs to find solutions to some of the challenges posed by networks of possibly hundreds or thousands of nodes. The course is intended for researchers, both from academia and industry, and engineers, as it covers both theoretical and practical issues. Many results achieved on field tests and real life applications will be shown to validate models and assumptions used in theoretical approaches; case studies will be discussed. Applications of. Wireless sensor networks that will be discussed include energy consumption reduction in buildings, health monitoring and industrial process control. All measurements ofwireless sensor networks, and field tests shown, have been carried out by the Authors research group at the University of Bologna. The course will move from description of fundamental issues of wireless networks, andin particular, towards discussion on the current trends of research and technology innovation in the field.

3. Professor Yik-Chung Wu, Qasim Chaudhari, and Erchin Serpedin has proposed a concept that With the help of recent technological advances in micro electromechanical systems and wireless communications, low cost, low power, and multifunctional wireless sensing devices have been developed. When these devices are deployed over a wide geographical region, they can collect information about the environment and efficiently collaborate to process such information, forming the so-called wireless sensor networks. These are a special case of wireless ad hoc network and assume a multi hop communication without a common infrastructure, where the sensors spontaneously cooperate to deliver information by forwarding packets from a source to a destination. The feasibility of WSNs keeps growing rapidly, and WSNs have been regarded as fundamental infrastructures for future ubiquitous communications due to a variety of promising potential applications: monitoring the health status of humans, animals, plants, and the environment; control and instrumentation of industrial machines and home appliances.
