Service Architectures, Alternative Architectures, and Looking Ahead
Kuok-Shoong Daniel Wong · 2011
This chapter first examines services and service architectures in mobile wireless networks. It gives examples of how certain service enablers, such as multimedia broadcast multicast services (MBMS), are built, looks at the larger picture of models of service architecture (e.g., intelligent network (IN), OSA), and shows how the industry has advanced from the early days to more recent models. Then the chapter considers a number of alternative network architectures, such as mobile ad hoc networks, mesh networks, sensor networks, and vehicular networks. In many application scenarios, these might be connected to, or eventually connected to, a wired network infrastructure; however, communications between nodes in these networks may traverse multiple wireless links in getting from source to destination. Moreover, significant communications between a pair of nodes in such networks may occur without any wired links in the path between the two nodes. Controlled Vocabulary Terms intelligent networks; mesh networks; mobile ad hoc networks; service-oriented architecture; vehicular ad hoc networks; wireless sensor networks
