The emergence of pervasive computing systems such as Internet Suspend/ Resume has facilitated ubiquitous access to a user’s personalized computing environment by layering virtual machine technology on top of distributed storage. This usage model poses several new challenges, such as establishing trust in unmanaged hardware that a user may access, and efficiently migrating virtual machine (VM) s...

Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. In fact, better modeling of SDI complexities will lead to more reliable plans for its development. A state...

GNU Compiler Collection (GCC) needs a strategy to support future multicore architectures, which will probably include heterogeneous accelerator-like designs with explicit management of scratchpad memories. Some have further restrictions; for example, SIMD has limited synchronization capabilities. Some platforms will probably offer hardware support for streaming, transactions, and speculation. T...

Ad hoc networks are a type of mobile network that functions without any fixed infrastructure. One of the weaknesses of ad hoc networks is that a route used between a source and a destination is likely to break during communication. To solve this problem, one approach consists of selecting routes whose nodes have the most stable behavior. Another strategy aims at improving the route repair proce...

Publish/subscribe system is a wide-area communication infrastructure which allows data distribution across unlimited number of publishers and subscribers. Both publishers and subscribers have the ability to express their interest in form of events, or a pattern of events by sending the subscription to the publish/subscribe network. The provisioning of basic security mechanisms such as authentic...
