12. Middleware is the link
13. Research Domains Middleware is a third-party computer software allowing to abstract, publish and interconnect services to exchange and process information. 13 [Le Mouël 2016]
14. Research Domains Ambient Intelligence is an IT vision focusing on an efficient and ergonomic support to human well-being and society concerns - anywhere, anytime - by using communicating, invisible, non-intrusive everyday-life embedded objects. 14 [Le Mouël 2016]

21. 1. How to deal with dynamism? 2. How to overcome scalability issues? 3. How to distribute decision-making? Research Contributions 21
22. Dynamism - Why is dynamism a challenge? - Services / Devices Heterogeneity ↗ - Mobility / Adaptation Needs ↗ - Complementary Proposals - Contextual Spontaneous Service Composition 22
23. 23 Ambient Environment
24. 24 Execution Environment Heterogenous Not Reliable Mobile
25. 25 Application Execution Flow
26. 26 Where? Application Ambient Environment
27. 27 What? Fine-grained Method-level Coarse-grained Bundle & Service-level [Golchay 2016] [Ibrahim 2008, Ben Hamida 2010]
28. 28 When? Automatic Proximity Cloud Spontaneous Semantic Service Composition [Golchay 2016] [Ibrahim 2008]
29. 29 How? Graph Cut with Multiple Destinations Collaborative Decision Cache Graph Coloring ACO Algorithms [Golchay 2016] [Ben Hamida 2010, Golchay 2016]
30. 30 ~10 devices ~50-100 services [Ben Hamida 2010] [Golchay 2016] [Ibrahim 2008] Time (ms) Node Number Execution Time AxSel with adaptation AxSel without adaptation Efficient ~25-55ms
31. Guidelines - Dynamism - Engineering Granularity - good offloading performance - Environment Volatility - good reactivity - Service & Semantics - bad scalability? 31
32. 1. How to deal with dynamism? 2. How to overcome scalability issues? 3. How to distribute decision-making? Research Contributions 32
33. Scalability - Why is scalability a challenge? - Services / Devices ↗ - Discovery, Information Dissemination? - One proposal - Pri-REIN - Prioritized Event Matching in Pub/Sub 33 [Qian 2015]
34. 34 Subscriber S1 channel.subscribe( (topic = « Temperature », value = [25,35]), (topic = « Location », value = [7,13]) ) Publisher P1 channel.publish( (topic = « Temperature », value = 28), (topic = « Location », value = 12) ) Matching Time?
35. 35 Subscribers Topic Ranges Geometric Point Enclosure Problem
36. 36 Index Structure: H-Tree - Interval-based - Tagging non-matching subscribers REIN
38. 38 Pri-REIN S3 will be served before S1 + Matching Time intervals
40. Guidelines - Scalability - Message-oriented Middleware - asynchronous - Distributed Publish/Subscribe - efficient, QoS - Engineering - genericity - Content Relevancy? 40
41. 1. How to deal with dynamism? 2. How to overcome scalability issues? 3. How to distribute decision-making? Research Contributions 41
42. Autonomy - Why is distributing decision-making a challenge? - Partial Knowledge - Local vs Global Optimization - One solution for one use-case - Ant-inspired Guidance Service in Smart City 42 [Lèbre 2016]
43. 43 Short-Path Problem Guidance Service Fuel Consumption Travel / Waiting Time Optimization
44. 44 Local vs Global Optimization Decision Partial Data
45. 45 When moving & service connected, what data to exchange? Path modification decision?
46. Ant-inspired Distributed Decision-making 46 ACO (Ant Colony Optimization) Vehicle Ant Pheromone Evaporation
47. 47 Data exchange: Pheromone map of vehicle m : Travel time at the maximum allowed speed Travel time measured by m at time t 0 The more is high, the more the information is old Pheromone evaporation: Pheromone validity time Evaporation gradient 0.5 init for unknown places
48. PKP KPP PDLAIS PPE CS 11,6 % 1,8 % 3,7 % 7,9 % 3,7 % Travel Time Gain k-path without pheromone k-path with pheromone Autonomous Intersections Local Pheromone Centralized Solution Normal Traffic 48
49. 49 k-path without pheromone k-path with pheromone Autonomous Intersections Local Pheromone Centralized Solution Earthquake PKP KPP PDLAIS PPE 80 % 40 % 20 % 20 % Arrival Percentage PKP KPP PDLAIS PPE CS 98 % 85 % 78 % 89 % 78 % Accident Arrival Percentage
50. Guidelines - Autonomy - Local decisions - can be globally efficient - Local decisions - robustness - Greatly depends on the use-case - Smart City: traffic ≠ parking 50 Tradeoff in favor of local decisions [Lin 2015, Lèbre 2016]
51. Concluding Remarks - Technology is here! - Middleware Dynamism, Scalability, ok! - Smart Middleware: Natural Receptacle for Autonomy! - Engineering 51
52. Concluding Remarks - Why are not Middleware & Ambient Intelligence in production ? - (when Middleware & Cloud Computing are main trend!) 52 & Internet of Things & Vehicular Networks
