The overall work package structure of SALUS and its breakdown is represented in figure below. The project has been split into 8 complementary work packages that will all converge to the global objective of SALUS to design, implement and evaluate a next generation communication network concept for Public Protection and Disaster Relief (PPDR) agencies, supported by network operators and industry, which will provide security, privacy, seamless mobility, QoS and reliability support for mission-critical PMR voice and broadband data services.
The main interactions between WPs are described below.
WP1: Management, is responsible for the overall management of the project, which includes the close monitoring of the project milestones, on-going tasks and resource consumption. WP1 activities include the organisation of management and technical meetings, audit preparation meetings, audits and facilitate the infrastructure for the compilation and delivery of internal or public documents, exchange of messages (e-mail reflectors, document templates, project FTP and web server, amongst others). WP1 is the interface with the EC for every issue that concerns the project; it conveys the information to the partners such as payments and timely delivery of project documents.
WP1 outputs are mainly the interim reports (every 6 months) in addition to – following FP7 guidance notes on project reporting – two periodic reports (every 18 months), one Final Report and a Report on the distribution of the EU financial contribution.
WP2: Use Cases Definition and PPDR Requirements, will develop the SALUS use cases from the three proposed scenarios: City Security, Temporary Protection and Disaster Recovery. The use cases will play a key role in the evaluation of the PPDR user community needs as they migrate into the future, and enables partners to assess how the new terminal capabilities may impact on long term evolution PPDR networks. With this in mind this activity will be performed with strong involvement of end-users and their organisations. The developed scenarios and use cases will become a reference point for further work on the system architecture (WP3), implementation and proof-of-concept (WP7). Furthermore, WP2 will also collect PPDR user requirements regarding different scenarios, enabling SALUS to create an overall view of current and future technologies that could be exploited to meet the requirements and support the development of the business cases in WP4.
The main outputs for WP2 are the SALUS use cases and the user requirements definition.
WP3: Enterprise Architecture Analysis and Specification, will use the uses cases developed in WP2 to determine the system level requirements that are necessary to design future PPDR systems – including the analysis of PPDR organisation strategy and information flows. System level requirements will be analysed and classified depending on the PPDR requirements (WP2) and the preliminary market study surveyed at WP4 and, will also receive feedback from the system integration (WP7) to incorporate improvements in the final SALUS prototype. WP3 will also enhance the Enterprise Architecture Framework in a way that it will be appropriate for the development of PPDR broadband networks and by the PSC-E community. This new SALUS Enterprise Architecture will be responsible for defining the functional building blocks of the System Architecture and their interfaces, describing the operational procedures for instantiating a concrete PPDR network based on the SALUS Enterprise/System Architecture, defining the procedural workflows of headquarters and operators involved in PPDR operations and defining solutions for interoperability with legacy systems and migration options.
The main outputs of WP3 are the system requirements, the Enterprise Architecture and the System Architecture, including security requirements.
WP4: Economic and Business Case Analysis, performs economical and business analysis of next generation PPDR networks with the goal to foresee the evolution of PPDR systems and associated business cases. Toward this goal this WP is committed to collect statistical data related to police forces and first responders in order to set-up a database of PPDR organisations across Europe which will also include relevant PPDR events. Other high priority goal of WP4 is the contribution towards spectral requirements of broadband PPDR networks. WP4 activities include proposals to spectrum regulation bodies for future PPDR spectrum allocations, including solutions that exploit the use of white spaces or opportunistic behaviour.
The main outputs of WP4 are the SALUS techno-economic analysis tool, PPDR organisations (and events) database, business analysis, risk assessment and performance metrics, PPDR spectrum requirements and frequency allocation proposals, PPDR total cost of ownership (TCO) and migration roadmap.
WP5: PPDR Security and Privacy, is responsible for the development and specification of the end-to-end security architecture between existing and next generation PPDR networks. This work will be based on trusted enterprise architecture and integrated down to in-field operations. The security architecture will be capable of providing strong authentication, confidentiality, integrity, intrusion detection and location privacy and also address redundancy (using ad hoc networks, sensors) for services continuity in extreme cases (e.g. when using augmented reality approaches where classical positioning cannot be used). Additionally, WP5 will design and develop security extensions for seamless mobility, propose end-to-end security and privacy support for interoperable PPDR communication systems and, develop and validate methods and techniques for flow based Intrusion Detection within the context of PPDR wireless systems. To address all these challenges, WP5 will use the use cases and the user requirements specified in WP2 and the overall architecture and interface definitions from WP3.
The main outputs of WP5 are the security and privacy analysis of TETRA/TETRAPOL PPDR, LTE and Wi-Fi networks, an interoperable architecture for security extensions for seamless mobility, PPDR end-to-end security and privacy mechanisms and, intrusion detection approaches and mitigation techniques.
WP6: PMR Services on PPDR Broadband Networks, has the goal to port and further enhance typical PMR voice and data services to operate on a LTE based broadband PPDR network with long-range Wi-Fi ad-hoc extensions. Towards this goal, WP6 will use the use cases and the user requirements specified in in WP2 and the overall architecture and the interface definitions provided by WP3 to design and implement: (i) Quality of Service, Quality of Experience and resilience solutions in multi-interface and multicast broadband PPDR networks; (ii) seamless and fast handover mechanisms in multi-interface and multicast broadband PPDR networks and (iii) interfaces, protocol and middleware components necessary to support PMR basic and supplementary voice and data services over broadband PPDR networks, such as LTE and ad-hoc IEEE 802.11 wireless technologies.
The main outputs of WP6 are connectivity, QoS and resilience solutions, seamless and fast vertical handover mechanisms, PMR-over-LTE services definition and protocol and middleware components for multi-interface PPDR broadband networks.
WP7: System Integration, Use Cases Validation and Evaluation of Broadband PPDR Platform, is responsible for the integration of the components and mechanisms to be developed in WP5 and WP6, according to the Architecture defined in WP3 and to build a working prototype of the SALUS PPDR platform to be used in the three Use Cases defined by WP2. The methodology for the validation of the use cases will involve the following steps: a) deployment of hardware and communications infrastructure; b) deployment of the PPDR platform; c) PPDR user training; d) trial activities; e) information collection and reporting. Furthermore, WP6 evaluation activities will be conducted in parallel with integration of the SALUS PPDR platform, including functionality, performance and security validation.
The main outputs of WP7 are the SALUS PPDR platform (prototype) and the evaluation and validation of the three use cases (City Security, Temporary Protection and Disaster Recovery). In addition, the lessons learned from the PPDR platform integration and the Use Case evaluation will be fed into WP3 for prototype improvements.
WP8: Exploitation Roadmap, Dissemination and Standardisation, is responsible for disseminating the knowledge generated by SALUS to the public by focused activities, to interact with the wider community and, to ensure post-project impact through an exploitation strategy. The dissemination activities include the organization of two SALUS conferences and a yearly advisory panel, the setup of a project web site, the creation of promotional material and other media (posters, brochures, etc.), publications at technology magazines/journals and conferences, talks given at workshops, exhibitions and industrial/end-users fora and, inter-project liaison activities. WP8 also includes standardization activities that, through standard liaisons, aim to contribute to the standardisation of protocols and architectures in relevant standardisation bodies, primarily IETF, ETSI, TETRA, TETRAPOL, 3GPP,TIA, WiMAX, IEEE 802.21. IPR rules and partner’s individual exploitation plans are also included in WP8 to ensure appropriate technology transfer activities are stimulated. Finally, WP8 activities also include training, which would be crucial to guarantee the success of the transfer of knowledge learned throughout the project. The estimated audience shall be between 10 and 20 participants per meeting and a at least 2 seminars will be organized. depending on the interest showed by the industry
The main outputs of WP8 are the dissemination, standardization and training activities related to SALUS and transfer of knowledge for SALUS technologies, the project web site, promotional material and demonstration media, individual partner’s exploitations plans, IPR statement and the report on the societal implications.
