In this paper, we discuss optimal controller placement for Software Defined Networks (SDN) and propose a non-zero-sum game based distributed technique. Our proposed technique is a simple and low-complexity solution which runs in real-time. This can be implemented as an optimization engine at each SDN controller. The optimization engine at each controller(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)
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. These(More)
Internet of Things (IoT) devices are typically deployed in resource (energy, computational capacity) constrained environments. Connecting such devices to the cloud is not practical due to variable network behavior as well as high latency overheads. Fog computing refers to a scalable, distributed computing architecture which moves computational tasks closer(More)
Multipath Transport Control Protocol (MPTCP) has been originally proposed for the data centers. MPTCP aggregates multiple interfaces available at the end devices to provide improved throughput and reliability. These features of MPTCP can also be exploited in robotic and drone1 based communications. The biggest challenge observed in drone communication is(More)
