Rapid advances in Wireless Sensor Networks (WSNs) indicate that they are becoming increasingly complex. Consequently users and applications are becoming more demanding. Due to unique characteristics of WSNs, like small dimensions and limited resources and capabilities, energy consumption is imposed as one of the key factors. WSNs are becoming the primary research field for many ...
Sensor networks are expected to play an essential role in the upcoming age of pervasive computing. Due to their constraints in computation, memory, and power resources, their susceptibility to physical capture and use of wireless communications, security is a challenge in these networks. The scale of deployments of wireless sensor networks require careful decisions and ...
In non-stationary environment, dynamic resource reservation schemes operating in harmony with the variability in demand patterns may provide efficient mechanisms for resource utilization and guarantee QoS (Quality of Service) compliance. In this paper, the authors identify the challenges that need to be addressed in designing a three level core which consists of policy making, packet ...
Cloud computing, is an emerging computer technology that provides users to remotely store their data in a server and provide services on-demand. Since remote data storage is here, data security and privacy is the most critical issues. Users can read, write and store data to cloud. To protect the confidentiality of the data stored, the ...
Many of the public cloud computing services have appeared for data storage in group applications. Two important problems that arise when sharing group data in public cloud are the privacy and security of group member’s data. Cloud service providers are separate administrative entities and users don’t have access to the cloud internal operational details. Because ...
Wireless mesh network is the emerging to be the dominant technology for next generation wireless networking as it is advantageous over other wireless technologies. Load balancing mechanism at router level is essential for wireless mesh network in configuring and maintaining the topology of the network. The performance of network paths is governed by routing metrics. ...
The problem of Optical Character Recognition (OCR) needs, as a first prerequisite, a good and powerful algorithm for binarization of scanned text. Most of the available algorithms used for binarization, uses the concept of thresholding. Such algorithms, in spite of being powerful, simple and the one with very small computational cost, are sometimes less efficient ...
Intrusions are those activities that violate the security policies of a system and intrusion detection systems are used to identify those intrusions. As the networks and new technologies are growing fast new intrusions are also introduced day-by-day. Therefore supervision of communication systems get more complicated. Intrusions are detected using alerts. Correlation of alerts is by ...
Due to the vast diversity of available cloud services, it is difficult for a customer to decide which cloud service satisfies their requirements at the most. To ease the customer’s cloud service selection process an efficient ranking algorithm is required. Quality of Service (QoS) helps in identifying the customer’s requirements and thereby aiding in optimal ...
Some wise scientist once said that control system is a system where the authors can shut down the machine whenever they want. That’s the difference between controlled and uncontrolled machine. Their paper is about make this control system efficient and dynamic. As the name suggest control is for controlling the motor from remote place, look ...
