“…Identifying the failed service is straightforward for the centralized protocol as compared to the decentralized one since the local proxy controls the execution of each service in the centralized protocol. However, in the decentralized protocol, as discussed in Yaser Fawaz et al [26], the failed service can be identified through the use of acknowledgment messages (ACKs). When an ASP executes an adaptation service S and forwards the partially adapted data to the next ASP, it sends an ACK message to the local proxy to inform that the service S has been executed.…”

Multimedia content adaptation has been proved to be an effective mechanism to mitigate the problem of devices and networks heterogeneity and constraints in pervasive computing environments. Moreover, it enables to deliver data taking into consideration the user's preferences and the context of his/her environment. In this paper, we present an algorithm for service composition and protocols for executing service composition plan. Both the algorithm and the protocols are implemented in our distributed content adaptation framework (DCAF) which provides a service-based content adaptation architecture. Finally, a performance evaluation of the algorithm and the protocols is presented.
