Dynamic Secure-Aware Real Time Scheduling Algorithm for Packet Switched Network

Now a day wireless networks are mostly preferred over wired networks because wireless networks are flexible and required no wire. If we talk about successful communication then end to end delivery of message is very important. In a heavy loaded networks scheduling of packets are key, by the proper scheduling of packets we can improve the guarantee ratio hence overall performance of the network is improved. If we focus on real time communication then real time packet scheduling plays an important role for enhance the performance of the system. In any network security plays a vital role, to protect the data from intruder and many security threats proper security of data is very important. So we can say that overall performance of the system is a combination of security and scheduling. In this paper we talk about real time packet scheduling in wireless networks. Here we use Dynamic Secure-Aware Real-Time Scheduling Algorithm for Packet Switched Network [DSASA]. This is a dynamic real time packet scheduling technique which reduce packets drop, increase guarantee ratio of data traffic and provide security for data packets

A critical analysis of research potential, challenges and future directives in industrial wireless sensor networks

In recent years, Industrial Wireless Sensor Networks (IWSNs) have emerged as an important research theme with applications spanning a wide range of industries including automation, monitoring, process control, feedback systems and automotive. Wide scope of IWSNs applications ranging from small production units, large oil and gas industries to nuclear fission control, enables a fast-paced research in this field. Though IWSNs offer advantages of low cost, flexibility, scalability, self-healing, easy deployment and reformation, yet they pose certain limitations on available potential and introduce challenges on multiple fronts due to their susceptibility to highly complex and uncertain industrial environments. In this paper a detailed discussion on design objectives, challenges and solutions, for IWSNs, are presented. A careful evaluation of industrial systems, deadlines and possible hazards in industrial atmosphere are discussed. The paper also presents a thorough review of the existing standards and industrial protocols and gives a critical evaluation of potential of these standards and protocols along with a detailed discussion on available hardware platforms, specific industrial energy harvesting techniques and their capabilities. The paper lists main service providers for IWSNs solutions and gives insight of future trends and research gaps in the field of IWSNs
