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…
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.…
Virtualized cognitive network architecture for 5G cellular networks
Cellular networks have preserved an application agnostic and base station (BS) centric architecture1 for decades. Network functionalities (e.g. user association) are decided and performed regardless of the underlying application (e.g. automation, tactile Internet, online gaming, multimedia). Such an ossified architecture imposes several hurdles against achieving the ambitious metrics of next generation cellular systems. This article first highlights the features…
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…
Ant Colony Optimization-Based Adaptive Network-on-Chip Routing Framework Using Network Information Region
The network-on-chip (NoC) system can provide more scalable and flexible on-chip interconnection compared with system bus. The performance of on-chip adaptive routing algorithms greatly relies on the adopted network information. To the best our knowledge, previous routing algorithms utilize either spatial or temporal network information to improve performance. However, few works have established a framework on analyzing the network information nor showed…
