Pervasive Computing “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it ” – Mark Weiser Think: writing, central heating, electric lighting, water services, … Not: taking your laptop to the beach, or immersing yourself into a virtual reality 10/20/2021 7

Smart Kitchen • Cooks to watch television, browse the Internet, play DVDs or CDs, check email or even order groceries online. • Can monitor stuff within fridge and notify You when you are running out of milk. • Maybe even call you if it detects that a store nearby has a sale of something that you are running out off. • Maybe help you with your diet by monitoring what and when you eat and trying to give you tips and where you may be gaining pounds 10/20/2021 15

Smart Kitchen • Stove that automatically selects the right temperature and cooking mode based on the type of food. • Download recipes into range and follow along with the instructions. Oven automatically controls temperature and cooking times as per recipe • Coffee machine that can detect the owners cup and brew a cup according to that owners preferences • Microwaves that read UPC barcode and figure out cooking times 10/20/2021 16

Smart Cars • The intelligent automobile combines improved features for navigation, communication, maintenance and safety - and with silicon-based driver recognition through smart cards or fingerprints, all this can be efficiently personalized. • Getting traffic updates to feed into GPS • Voice recognition, Keyless entry, On-star • Internet enabled cars for people to check emails, browse etc while on the road (hopefully not the driver) 10/20/2021 17

Trauma Pod • A DARPA-sponsored project to enable a future generation of unmanned medical systems to save lives on the battlefield • A Trauma Pod will have no human medical personnel on-site to conduct the surgery and will be small enough to be carried by a medical ground or air vehicle. • A human surgeon will conduct procedures from a remote location using teleoperated surgical manipulators with support from automated robotic systems • Phase 1 will perform an unmanned surgical procedure within a hospital OR space. 2005: da Vinci Surgical Robot 2020: Automated Trauma Pod treats wounded soldiers on the battlefield. 10/20/2021 18

UMBC’s role in Trauma Pod • Our role focuses on using RFID technology to track the location and use of medical tools and supplies in the OR • And to integrate this information with • Legacy supply chain systems • Hospital and patient records 10/20/2021 19

Mo. GATU: TIVO for Mobile Computing A mobile computing vision and a problem • Devices “broadcast” information and service descriptions via short-range RF (802. 11, Bluetooth, UWB, etc. ) • As people and their devices move, they can access this data, but only while it’s in range • The data may be out of range when it’s needed • Devices must anticipate their information need so they can cache data when it’s available • Based on user model, preferences, schedule, context, trust, … • Compute a dynamic utility function to create a “semantic” cache replacement algorithm 10/20/2021 23

Mo. GATU’s distributed belief model • Mo. GATU is a data management module for MANETs • Devices send queries to peers • Ask its vicinity for reputation of untrusted peers that responded -- trust a device if trusted before or if enough trusted peers trust it • Use answers from (recommended to be) trusted peers to determine answer • Update reputation/trust level for all responding devices • Trust level increases for devices giving what becomes final answer • Trust level decreases for devices giving “wrong” answer • Each devices builds a ring of trust… 10/20/2021 24

Service Discovery and Composition • Develop a peer-to-peer caching based distributed service discovery mechanism • • Integrated with routing layer for better performance Uses semantic service descriptions Caching of “neighboring services” Selective forwarding of requests • Broker-based Service Composition • • Dynamic Broker selection based mechanism Distributed Broker-based mechanism Utilizes the peer-to-peer service discovery layer Source-monitored fault-tolerance 10/20/2021 25
