Energy consumption is a vital resource to be controlled to extend the longevity of a wireless sensor network. In a multihop routing, lifetime as well as throughput of the network could be increased by selecting the forwarding node intelligently. The existing energy-aware routing protocols either do not jointly consider the network performance and energy(More)
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,(More)
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,(More)
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(More)
Cognitive radio networks (CRNs) have received considerable attention and viewed as a promising paradigm for future wireless networking. Its major difference from the traditional wireless networks is that secondary users are allowed to access the channel if they pose no harmful interference to primary users. This distinct feature of CRNs has raised an(More)
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(More)
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(More)
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.
