We use space shift keying (SSK), which is the simplest form of spatial modulation (SM), to present and analyze the idea of spatial modulation in line-of-sight (LOS) conditions. We show that SSK can operate effectively in LOS conditions provided that the antennas are properly placed at TX and RX such that a high-rank LOS-MIMO channel…

Liar, Liar, IM on Fire: Deceptive language-action cues in spontaneous online communication
With an increasing number of online users, the potential danger of online deception grows accordingly – as does the importance of better understanding human behavior online to mitigate these risks. One critical element to address such online threat is to identify intentional deception in spontaneous onlinecommunication. For this study, we designed an interactive online game…
Reliable data communication over HF link using System on Chip technology
HF communication is one of the important aspects in military radio communication, even though it has been seen as a difficult and tedious task because of instability of ionosphere layer. To make HFcommunication becomes easier, many digital techniques have been introduced. It is also desirable to have all these techniques implemented in a single radio. This can be achieved…
Energy Efficient COGnitive-MAC for Sensor Networks Under WLAN Co-existence
Energy efficiency has been the driving force behind the design of communication protocols for battery-constrained wireless sensor networks (WSNs). The energy efficiency and the performance of the proposed protocol stacks, however, degrade dramatically in case the low-powered WSNS are subject to interference from high-power wireless systems such as WLANs. In this paper we propose COG-MAC, a novel cognitive medium…
A Cognitive Approach for Performance Enhancement of Wireless Mesh Networks
Providing the required quality of service (QoS) for clients in a wireless mesh network (WMN) is a challenging task. This is due to the complex architecture of the WMN and unpredictable behavior of the wireless links and the intermediate nodes. This can be alleviated by introducing a cognitive mechanism within the WMN. In this paper, a WMN is developed,…
Designing multi-level connectivity for IoT-enabled SmartX Boxes
In this paper, we discuss about a futuristic design for multi-level connectivity that plays the pivotal role in enabling IoT services employing the hyper-convergent SmartX Boxes.
IoT service framework based on mega data center and micro data center in PMIPv6 environment for smart devices
Internet of Things (IoT) is a new technology that allows many smart devices to interact with each other after they are connected to the Internet. Smart devices can communicate with each other as well as with other applications to gather useful information/tracking items/provide location which can be used to improve that service or obtain feedback.…
Energy Efficiency Maximization Framework in Cognitive Downlink Two-Tier Networks
To support the surge in wireless data traffic, the spectrum and energy efficiencies of cellular networksshould be largely increased. Heterogeneous two-tier architecture has been identified as one key solution. However, small-cell deployment raises questions about the resulting energy efficiency and interference mitigation. Therefore, we propose an energy-efficient and cognitive spectrum sharing scheme between primary macrocell and secondary small…
Business modeling for TV white space networks
Database-assisted TV white space network is a promising paradigm of dynamic spectrum sharing, and can effectively improve spectrum utilization and alleviate spectrum scarcity via centralized control of TV white space databases residing in the cloud. In this article, we discuss business modeling for a database-assisted TV white space network, which is very important for wide commercialization of this…
Efficient multiple personal wireless hub assignment in next generation healthcare facilities
Low power wireless sensors, personal wireless hub (PWH) and receivers can reduce the workload of the paramedic staff in a hospital. In this paper, we use multiple PWHs to transfer sensor data to the main central controller, which helps the wireless sensor devices. A well designed multiple PWH assignment and power control scheme can reduce…
