Considerations for multiple network and service provider environments are regarded as essential for the successful deployment of convergence services in NGN. Event driven service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers. This paper first describes the deployment model of NGN convergence(More)
PRoPHET is a probabilistic routing protocol for Delay Tolerant Networks (DTNs). In PRoPHET, the delivery probability is calculated based on the history of encounters and transitivity. However, if two nodes meet frequently during a short time interval, the delivery probability between these nodes increases rapidly. To solve this problem, PRoPHETv2 uses the(More)
