“…Researches on dynamic service selection were focused in a matching between the user's request and the available service based on matching keywords (Zhang et al, 2018) and requires the requester to specify several constraints including the dependency of atomic, the user's preference and so on (Jin‐zhonga et al, 2010; Toma, Roman, et al, 2005). The composability of Web services is also important in service selection (Omrana et al, 2012). Recently, Tiwari and Mishra (2018)) proposed a CPN based Reliability in Composite Web Service (CPN‐RCWS).…”

E-government has become a strategic tool for managing public administration. It makes it possible to improve interoperability between government's computer systems agencies. Taking profit to technological advances, notably the internet and web services, it has been associated with service-oriented architectures (SOA). Serviceoriented e-government has thus grown rapidly in developed countries. He has also gradually established itself in many projects in developing countries to take advantage to the economic benefits derived from SOA. However, when the activity of stakeholders becomes important in an e-government based on SOA, the scalability becomes a major challenge. This is even more striking in developing countries, which suffer from less robust infrastructures and poor energy supply. The scalability has its origins mainly in dynamic service composition operations. This is why this work proposes to improve the dynamic service composition layer to deal with the scalability in case of service-oriented e-government in developing countries. This makes it possible to construct and dynamically enrich each system with a service composition server, a registry and a library of requests associated with their composite services. Thus, each system checks its ability to process a request locally before sending it to a higherlevel system. The paper demonstrates that using this participatory approach, the latency of the majority of end-user requests is significantly shortened. Beyond this important aspect, our approach can provide with a good solution for Cameroon suffer from infrastructural insufficiency and energy instability. The evaluation of this architecture gave us satisfactory results.
