To speed up the HART task execution, this chapter next presents a latency sensitive HART task migration scheme for efficiently orchestrating tasks among human mobile users (MUs), central and decentralized computational agents (cloud/cloudlets), and robots across converged FiWi network infrastructures. Moreover, this chapter describes a bandwidth allocation scheme that allocates timeslots to MUs' broadband and task migration traffic at the same time. Furthermore, this chapter presents performance evaluation results of the proposed scheme. Importantly, this chapter compares the performance of the proposed task migration scheme with traditional schemes. This chapter is finally concluded by summarizing important findings and outlining open research issues for HA...

The Tactile Internet lies at the nexus of computerization, automation, and robotization. While necessary, low task execution time and ultra-reliable human-robot connectivity are not sufficient to unleash the full potential of the resultant human-agent-robot teamwork (HART) applications. In this paper, we propose a context- and self-aware HART-centric allocation scheme for both physical and digital tasks to coordinate the automation and augmentation of mutually beneficial human–machine coactivities while spreading ownership of robots across users over integrated fiber-wireless (FiWi) Tactile Internet infrastructures. In addition to realizing collective context-awareness via HART-centric task coordination, we aim at exploiting local self-awareness in order to improve the energy-delay performance of robots. Further, we present an analytical framework to estimate the packet transmission delay and human–robot connection reliability. Our results indicate that our proposed context- and self-aware HART-centric task coordination scheme obtains a low task execution time while minimizing the energy consumption and operational expenditures (OPEX) of mobile robots.

However, given human users’ different preferences for real-time HART task execution, e.g., lower delay and monetary cost, the selection of proper task coordination services has emerged as an important research problem by taking dynamically changing cloud agent/robot resources, network bandwidth utilization, as well as delay-sensitive and delay-tolerant HART task properties into account. To cope with these challenges, in this paper, we explore the synergy between caching, computation, and communications for achieving cost-effective HART task execution. To exploit the locality of different HART-centric tasks and local/non-local cloud agent/robot resources for different HART-centric task execution, we consider integrated fiber-wireless (FiWi) enhanced networks with computation task offloading as well as fiber backhaul sharing and WiFi offloading capabilities. More precisely, to minimize task execution delay and monetary cost, we propose a user preference aware HART task coordination framework that selects the appropriate dedicated or non-dedicated robot and cloud agent for given caching and computing HART task execution requirements. Further, to cope with varying bandwidth resources, we propose a proactive bandwidth allocation policy for the execution of both delay-sensitive and delay-tolerant HART tasks execution across FiWi enhanced network infrastructures. We evaluate the performance of our proposed preference aware task offloading scheme and compare it to various baseline schemes in terms of different key performance indicators, including the task execution time and monetary cost saving ratio, communication to computation ratio, and offloading gain overhead ratio. Our findings indicate that the proposed delay cost saving policy exhibits a 27% higher task execution time saving ratio and a 48% lower monetary cost saving ratio than the proposed monetary cost saving policy in a typical scenario.

As for passcode, a 4 bit binary number is used. To input the pass code, four two state switches are utilized. The pass code is stored in a memory. It can be changed after unlocking the lock system using valid pass code. We use D type flip-flops as memory. The comparator unit compares input codes with the stored code to generate the signal required to open the lock. The system is hardware implemented and has the versatility in application.

Bangladesh is one of the most disaster-prone countries in the world, and it has failed to offer a productive disaster administration framework that can help victimized people in times of need, particularly during the salvage and alleviation stages. Thus, there is a need for a framework that may help in the productive procurement of supplies to disaster zones. The always-diminishing cost of mobile phones and wide system scope of cellular innovation has empowered cellular telephones to work even in remote areas. The Android operating system also expands its ubiquity among youngsters for its minimal effort and high effectiveness. Since the utilization of cell telephones in Bangladesh is broad, the outline of a disaster administration framework as a portable application is paramount. The usage of such a framework would be a helpful instrument for post-disaster administration. The application environment for the proposed framework is Google"s Android operating system in light of the fact that it is the most prevalent portable working framework today. We outline both server side and client side interfaces for better disaster recovery operations. The proposed framework is useful for both disaster victims and the rescuers. The GPS of advanced mobile phones is utilized for discovering the area of the client, and is fit for sending their area directions to the server. The server corresponds with a legitimate database of the organization, and the organization distinguishes the current position of a disaster victim. Organizations included in post-disaster administration utilize Google Maps, which shows the position of disaster victims with an asked-for disaster severity number and his versatile number. The volunteers of the salvage group to pass on the message for making essential move. The server site classes the alleviation choice which originates from the victim and store into the database for further utilization. The proposed framework in this project may serve as a good starting point for a post disaster management system in Bangladesh.
