Architectures of mobile middleware: A taxonomic perspective

Complex decentralized applications, developed for emerging mobile computing paradigm, need support of mobile middleware platforms to enable coordination of active components of these applications. Recent works demonstrated that tuple space model can act as coordination medium for mobile middleware platforms, which are termed as tuple space based mobile middleware. Importance of these middleware are escalating day-by-day with changing network scenario, thereby demanding a better understanding of their current and future research directions. This motivating factor drives us to present a taxonomy of architectures for tuple space based mobile middleware. Proposed taxonomy is the new of its kind and is based on distribution pattern of tuple spaces within middleware and nature of identification of these tuple spaces. Multiple existing tuple space based mobile middleware are also considered and classified according to proposed taxonomy.
