Towards a hybrid approach of Primitive Cognitive Network Process and Self-Organizing Map for computer product recommendation

Products have similarities which can be analyzed to recommend products to consumers with different preferences. This paper combines Primitive Cognitive Network Process (PCNP) and Self-Organizing Map (SOM) to cluster products into appropriate categories on the basis of consumer preferences and product similarities. PCNP is an ideal alternative of Analytic Hierarchy Process (AHP) to quantify the […]

Channel, Queue and Delay Aware Resource Allocation in Buffer-Aided Relay-Enhanced OFDMA Networks

Resource allocation is an important factor in providing different varieties of services in next generation broadband wireless systems. In this paper we consider dynamic routing and subchannel allocation for providing Quality of Service (QoS) in the downlink of OFDMA networks enhanced with buffering relays. Specifically, we consider satisfying the QoS requirements of both delay-sensitive users […]

Scaling Limits of MEMS Beam-Steering Switches for Data Center Networks

Transparent optical circuit switching can improve the aggregate bandwidth, scalability, and cost of data center networks provided it can meet the performance requirements on switching speed, port count, and optical efficiency. Here, we examine the theoretical scaling limits of transparent non-blocking optical switches based on MEMS electrostatic tilt mirror devices. Using physical optics and electromechanics, […]

A Potential-Game Approach for Information-Maximizing Cooperative Planning of Sensor Networks

This paper presents a potential-game approach for distributed cooperative selection of informative sensors, when the goal is to maximize the mutual information between the measurement variables and the quantities of interest. It is proved that a local utility function defined by the conditional mutual information of an agent conditioned on the other agents’ sensing decisions […]

Swarm and Classical Based Routing Schemes in Wireless Sensor Network

The wireless Sensor Network is basically an application specific network. It is not possible to generalize an optimal solution for the WSN problems. It totally depends upon application selection and resource availability. Since in WSN a large no of sensor nodes are deployed so each sensor behaves as receptor and forwarder for the data from […]

Impact of Solar Panels on Power Quality of Distribution Networks and Transformers

This paper presents an investigation on the impact of solar panels (SPs) on the power quality of distribution networks and transformers. Both solar farms and residential rooftop SP are modeled with the distribution network according to Canadian Utility data. Total harmonic distortion of voltages and currents on both sides of the distribution transformer are monitored […]

On analyzing Indian cellular traffic characteristics for energy efficient network operation

Recent proliferation of mobile devices and high market demand have pushed power consumption of cellular networks to high levels in India. At the same time, the marginal gains to telecom operators for providing services have dwindled. Thus, a gap is slowly building up in the demand and supply of telecom services. The effect is adverse […]

Engineering Parallel Algorithms for Community Detection in Massive Networks

The amount of graph-structured data has recently experienced an enormous growth in many applications. To transform such data into useful information, fast analytics algorithms and software tools are necessary. One common graph analytics kernel is disjoint community detection (or graph clustering). Despite extensive research on heuristic solvers for this task, only few parallel codes exist, […]

Countermeasure for Reinforcement Swap Attack against Directed Diffusion in Wireless Sensor Networks

Directed Diffusion is a data centric protocol that focuses on the energy efficiency of the networks. It is interest based routing protocol in which communication occur hop-to-hop rather than end-to-end in wireless sensor networks. Hop-to-hop communication provides link diversity which helps to overcome obstacles like failure of intermediate node on communication path. Directed Diffusion protocol […]

Design of an automotive safety system using Controller Area Network

Most of the people are using vehicles which have become the most important part in our life for comfort transportation. In existing system the main snags are cost as well as the first one are glaring effect accidents due to opposite vehicle headlight illumination at night time driving. Second one is the short circuit fault […]
