A Software Solution for Mobile Context Handoff in WLANs *
This paper presents a software solution for mobile context handoff in IEEE 802.11 Wireless Local Area Networks (WLANs) for a context-aware system in the campus area at Fatih University. This project provides a seamless mobility infrastructure to mobile applications that were developed as a part of SOWCAS (Service-Oriented Wireless Context-Aware System) project. SOWCAS is a distributed pervasive system having a context-aware middleware server, proxy servers and mobile clients that support context-awareness and high adaptation to context changes for heterogeneous indoor and outdoor mobile applications. A handoff daemon named as Scriptex in Perl scripting language was developed. Scriptex provides a generic solution that is free from operating system and hardware implementations.
