In the world of Internet of Things (IoT), it is desired that every IoT device is able to communicate with the network all the time. Among various technologies to enable network connectivity, Long Term Evolution (LTE) is by far the most ubiquitous technology to provide coverage for IoT devices. The IoT devices are inherently resource constraint and efficient communication is one of the primary requirements...
Indoor wireless communication using Wireless Fidelity (WiFi) is becoming a major need for the success of Internet of Things (IoT) and cloud robotics in both developed and developing countries. With different operating conditions, interference, obstacles and type of building materials used, it is difficult to predict the path loss components in an indoor environment, which are crucial for the network...
Licensed Assisted Access (LAA) has been proposedby 3rd Generation Partnership Project (3GPP) in order touse Long Term Evolution (LTE) in the un-licensed band. Asthe centralized control of LAA has to co-exist with existingdistributed Wireless Fidelity (WiFi), efficient Listen Before Talk(LBT) technique is required to reduce interference and improvespectral efficiency. In this paper, we have proposed...
Robotics is penetrating into all aspects of human life from being a helper at daily chores to a technician performing precision operations at warehouse. Deploying mobile robots and Unmanned Aerial Vehicles (UAV) to conduct search and rescue operations during industrial accidents and natural disasters is one of the recent applications of robotics. These robots/UAVs are controlled remotely over wireless...
Information Centric Networking (ICN) advocates the philosophy of accessing the content independent of its location. Owing to this location independence in ICN, the routers en-route can be enabled to cache the content to serve the future requests for the same content locally. Several ICN architectures have been proposed in the literature along with various caching algorithms for caching and cache replacement...
With the advancement of smart phone technologies cellular communication has come to a stage where available bandwidth has surpassed the user demands. Moreover, the well organized yet stubborn architecture of cellular networks sometimes creates hindrance to the optimal usage of the network resources. Due to this, a User Equipment (UE) experiencing a poor channel to the evolved NodeB (eNB) suffers with...
Information Centric Networking (ICN) has been envisioned as the next alternate way of communication for the future Internet. In ICN, the en-route routers cache the popular content to serve the future requests locally rather than getting them from the source on every repeated request for the same content. Several caching and cache replacement policies have been proposed in the literature. All these...
Information Centric Networks (ICN) envisions a radical shift from existing host-centric networking of the Internet to a content centric networking. Caching is an important and integral part of ICN. In ICN, the requested contents that are downloaded from the original source are stored at intermediate on-path routers. With increase in similarity in the requests by multiple users, similarity of contents...
Machine-to-Machine (M2M) communication is expected to be one of the major application areas of cellular communications in near future. In cellular M2M communication, although, the gateway layer provides smooth management to underlaying cellular networks, it over-burdens the network in terms of delay and bandwidth utilization. Therefore, with the recent advancements in direct Device-to-Device (D2D)...
Information Centric Networks (ICN) has emerged as a new Internet paradigm where the users are being provided seamless access to contents rather than the host as in classical approach. For ICN realization, the current Internet requires architectural changes. These changes must be incorporated such that existing applications continue running without any difficulties. In this paper, we introduce a novel...
Device-to-Device (D2D) communication underlaying a cellular infrastructure has recently gained tremendous interest not only by the researchers but also by cellular operators and equipment manufacturers. In this paper, we have introduced a novel D2D communication scheme which can be realized by a D2D discovery mechanism along with a two-phase interference-aware optimal D2D uplink scheduling scheme...
Information Centric Networks (ICN) is proposed as an alternative design for content-based communication rather than host-to-host-based communication. In ICN architecture, the data are cached or stored at intermediate routers to satisfy future demands locally without repeatedly getting it from the original source. For ICN architecture to work efficiently, caching policies must be defined such that...
Information Centric Networking (ICN) has been proposed as an alternative design for the Internet with a focus on content centric communication rather than host-to-host communication such as telnet or ftp. This requires the data to be cached or stored at intermediate routers to satisfy the future demands for the same contents locally. The existing caching policies are either suboptimal or not suitable...
In a distributed control wireless ad-hoc network, network performance is significantly effected by multi-user interference. In such networks, transmit power control can enhance the energy usage as well as the QoS performance. Although, the effects of hidden/exposed terminals on the system throughput in wireless ad-hoc networks have been studied extensively, the IEEE 802.11 with variable transmit power...
In a typical cognitive radio network (CRN), secondary users can only access the channel when they do not harmfully interfere with the primary users. Therefore, an accurate estimation or prediction of interference from secondary users to primary users is essential. In this paper, we tackle the problem of interference estimation in a channel in presence of one PU and multiple SUs. We solve this problem...
The extremely long propagation delay between interplanetary nodes poses challenges to the investigation of Store-and-forward Deep Space Autonomous Network (DSAN). Long propagation delay combined with scarcity of energy at the planetary wireless nodes and relays, introduces new dimensions to the congestion control challenge. In this paper, we take advantage of long propagation delay between nodes and...
In a wireless sensor network, as the sensor nodes have limited energy, it is important to minimize nodal energy consumption due to message communication to extend the network lifetime. Existing forwarding protocols either do not consider network performance and energy saving jointly, or they are not distributed. In this paper, we propose a hybrid approach, called minimum consumption maximum remaining...
