The project work has been divided in the subsequent workpackages each producing concrete results, measured through deliverables (and milestones) and covering all aspects of the project, from management and technical developments to the demonstrations and dissemination of results.

Work package 1:                                                             Project Management and Impact Monitoring
Task 1.1 (Project Co-ordination-Administrative & Management)
Task 1.2 (Project Promotion and Web-site): The relevant activities for this task are the specification and development of the project website which will be the base for the dissemination activities. Moreover, other plans will include the project promotion through LinkedIn and Facebook.
Task 1.3 (Project Promotion and Web-site): The relevant activities for this task are the specification and development of the project website which will be the base for the dissemination activities. Moreover, other plans will include the project promotion through LinkedIn and Facebook.

D1.2: Final project management report                                                             [M24]

Work package 2:                                                             Architecture, Scenarios and Validation Strategy
Task 2.1 (System Requirements and Architecture): This task will establish project?s technical, business and social requirements, will design the high-level INCEPTION architecture and the specification of the system?s components, interfaces and APIs.
Task 2.2 (Design of demonstrations and validation scenarios): This task will cope with the design and validation part of the foreseen scenarios. Based on system requirements and architecture established in Task 2.1 a detailed plan for the project demos will be produced, including identification of equipment type, description of interfaces and interconnection among the several components. Validation procedures will be defined as well as success metrics for the different scenarios in order to validate the project outcomes against the objectives.

Work package 3:                                                             Participatory Sensing Economics and Game Theoretical Aspects
Task 3.1 (Market Service-Algorithmic and Game Theoretical Aspects): This task will develop the Market Service module and will consist of two subtasks. The first one is the algorithmic component, where given the available data and the set of requests, we need to decide which requests are satisfied and by which data. We will investigate the computational complexity and the design of efficient approximation algorithms and heuristics. The second subtask will deal with price-setting and game theoretic aspects. Given the allocation of data to requests, one then needs to decide how to charge the users, aiming to optimise the economic benefits of the involved participants and creating an efficient, sustainable market of sensor data. The pricing scheme should resolve various issues such as:
  1. Fairness: e.g. in the case that multiple users are using the same data, each user should contribute according to how important it is for her.
  2. Truthfulness: Users are entities who first care to maximize their own utility. The pricing then should be in a form that prevents the players from misreporting their true willingness to pay.
  3. Simplicity: It is typically the case in auctions and other mechanism design settings that the users know exactly how the pricing rule works and what their strategy should be, but for this to happen, we have to ensure that the rule should be simple enough so that all users can easily understand it.
We will study the design of such pricing schemes and compare them with regard to the above-mentioned properties.
Task 3.2 (Incentive Mechanisms ): This task will design and implement appropriate incentive mechanisms. One promising approach is based on some internal virtual currency to encourage users to participate to the system by providing their sensor data. The basic idea is that users have accounts and obtain income by selling sensor data, which they need to spend it in order to have access to applications. This is a more general mechanism than simple direct reciprocation (tit-for-tat), since a user may get virtual money by generating income useful to application A, and spend it to access application B. Sophisticated applications may offer incentives by offering different qualities and charge users differently.

Work package 4:                                                             Participatory Sensing Communication Infrastructure
Task 4.1 (Market Service-Algorithmic and Game Theoretical Aspects): To efficiently implement the Marketplace, this task will design and build efficient advanced data structures where all descriptions of data available to the system will be stored, as well as efficient access methods to search for available data. Data will be modelled as multidimensional messages which are either individual or streams. The BigTable will be implemented as a service, where publishers advertise data items they sell and subscribers are able to query for items they want to acquire.
Task 4.2 (INCEPTION Connectivity Middleware-ICM) ): This task will design and implement a middleware-type of architecture that i) provides an extensible and interoperable programming framework, ii) is designed to encompass large growth in scale and iii) supports real-time, fault-tolerant execution by making mobility and potential disconnections and failures transparent to the other entities in the system. The middleware will be responsible for implementing the appropriate mechanisms for sensor data collection and monitoring, user profiling, performing system re-con?guration in response to disconnections, and message routing. Furthermore, this task will provide the APIs for operating over heterogeneous devices and operating systems.
Task 4.3 (Applications):This task will design and implement a set of simple applications designed to demonstrate the project principles and assist the evaluation of the project. The applications will be designed to run on Android and iOS operating systems and will be evaluated in a laboratory environment in the context of WP5. After the end of the project these applications will be provided for free to users and developers through the Android and iStore marketplaces and project?s web-site.

Work package 5:                                                             Prototype Deployment, Demonstration and Evaluation
Task 5.1 (System Integration):This task aims to achieve the expected functionality at system level, as well as validate the proper interworking of system components, functions and available applications. More specifically, will develop an integrated prototype and check the system architecture compliance to the sub-system requirements and interfaces as defined in WP1. Furthermore, will fine-tune and update the sub-system and the interfaces, verify their conformity (functional and performance) and recommend performance improvements and features for future design iterations.
Task 5.2 (Incentive Mechanisms ): This task will provide a complete evaluation of the produced system according to the requirements, project objectives and success measures as defined in WP1. The results will be recorded in D5.2 (INCEPTION system evaluation report). Furthermore, the demo results will be analysed and evaluated in terms of quantitative and qualitative indicators, such as: platform/software functionality, accuracy of transmitted and stored data, system usability in terms of ease of use and accessibility etc.
