Proximity services supporting network virtual memory in mobile devices

ABSTRACT

Wireless networked embedded terminals like personal digital assistants, cell-phones or sensor nodes are typically memory constrained devices. This limitation prevents the development of applications that require a large amount of run-time memory space. In a wired cum wireless scenario, a potentially unlimited amount of virtual memory can be found on remote servers installed on the wired network. However, virtual memory access requires performance constrained and lossless data flows against terminal handover between coverage areas. In this work, we present an infrastructure aimed at providing efficient remote memory access to mobile terminals in a wireless LAN connected to a multi-hop network. The behavior of the infrastructure has been theoretically studied, implemented and tested w.r.t. various traffic conditions and handover events.
