We consider applications, such as indoor navigation, evacuation, or targeted advertising, where mobile users equipped with a smart-phone class device require access to sensor network data measured in their proximity. Specifically, we focus on efficient communication protocols between static sensors and users with changing location. Our main contribution is to predict a set of possible future paths…

Range Enhanced Packet Classification Design on FPGA
The future of fast Internet needs powerful routers to support abundant network functionalities, such as firewall, QoS, and virtual private networks by classifying the packets into different categories based on a set of predefined rules, so-called multi-field packet classification. Traditional packet classification that considers only 5 tuple fields is not sufficient for today’s complicated network requirements. OpenFlow switch was born to…
A symbolic system synthesis approach for hard real-time systems based on coordinated SMT-solving
We propose an SMT-based system synthesis approach where the logic solver performs static binding and routing while the background theory solver computes global time-triggered schedules. In contrast to previous work, we assign additional time to the logic solver in order to refine the binding and routing such that the background theory solver is more likely…
Representation of spectrum sensing experimentation functionality for federated management and control
Spectrum sensing is one of the core functionalities of a true cognitive radio (CR) that supports operation over a broad range of frequencies and can autonomously adapt transmission parameters to the operating environment. There are several types of hardware ranging from sophisticated (i.e. Nutaq Radio420X FPGA mezzanine card) to low cost (i.e. WiSpy) that can be used to…
Performance analysis in direction oriented graded cognitive network using Bayesian model approach for path determination
Some of the challenges involved in current Internet routing are limitations of the process enabling routing techniques, handling of explosion of messages and absence of awareness about the environment. This paper presents a comparative analysis using Bayesian model of a network having a randomly distributed quality parameters when subjected to quality grading and direction oriented for optimal…
Cooperative sensing under imperfect feedback channels in dynamic spectrum access networks
In this paper, cooperative spectrum sensing under perfect and imperfect feedback channels is investigated. In particular, the optimal number of cognitive radios (CRs) required to minimize the total error of the sensing process when a perfect/imperfect reporting channels is derived. We show that the total error is always greater than zero regardless of the number…
A 340 mV-to-0.9 V 20.2 Tb/s Source-Synchronous Hybrid Packet/Circuit-Switched 16 × 16 Network-on-Chip in 22 nm Tri-Gate CMOS
A 16 × 16 mesh network-on-chip (NoC) is fabricated in 22 nm tri-gate CMOS for high-throughput, energy-efficient on-chip interconnect in multi-core processors and systems-on-chip. The NoC connects 256 nodes that are each in their own voltage and clock domain using 5-port routers and 112 b, 855 μm data links. Source-synchronous operation eliminates global clock distribution…
Optimal Configuration of Network Coding in Ad Hoc Networks
In this paper, we analyze the impact of network coding (NC) configuration on the performance of ad hoc networks with the consideration of two significant factors, namely, the throughput loss and the decoding loss, which are jointly treated as the overhead of NC. In particular, physical-layer NC and random linear NC are adopted in static…
Implementation of network intrusion detection system using variant of decision tree algorithm
As the need of internet is increasing day by day, the significance of security is also increasing. The enormous usage of internet has greatly affected the security of the system. Hackers do monitor the system minutely or keenly, therefore the security of the network is under observation. A conventional intrusion detection technology indicates more limitation…
Mobile Sink based Adaptive Immune Energy-Efficient Clustering Protocol for Improving the Lifetime and Stability Period of Wireless Sensor Networks
Energy hole problem is a critical issue for data gathering in Wireless Sensor Networks. Sensors near the static sink act as relays for far sensor and thus will deplete their energy very quickly, resulting energy holes in the sensor field. Exploiting the mobility of a sink has been widely accepted as an efficient way to…
