Development of an IEEE 802.21 Media Independent Information Service

Media independent vertical handover in hybrid networks — From standard to implementation

“…According to the tests exemplified in [9], the current implementation of the MIIS can provide a response in less than 100 milliseconds for hundreds of clients generating requests, if a regular use server is used. Given this fact, the web-service solution for the MIIS is not to be neglected.…”

“…The call to the Information Service will be made through a web-service request, as detailed in [9], were some serving rate capabilities are given for MIIS entity, proving that this solution could offer good performances. According to the tests exemplified in [9], the current implementation of the MIIS can provide a response in less than 100 milliseconds for hundreds of clients generating requests, if a regular use server is used.…”

A Survey of Context Aware Vertical Handover Management Schemes in Heterogeneous Wireless Networks

“…A project was introduced with the support of NATO called reconfigurable interoperability of wireless communications systems (RIWCoS). The project was later on briefly described in different research works [32][33][34][35]. RIWCoS modified the existing MIH standard for integrating new services to support user centricity and making handover decisions on the basis of different contexts like MN's position extrapolation, maximum data flow rate, and signal power of a PoA.…”

A streaming application for vertical handover testing in wireless hybrid access networks

“…2). The target laptop used to demonstrate the vertical handover is connected to the Internet, and hosts of RIWCoS software modules [6][7][8] [9]. Another laptop is configured as a wireless access point, in order to have the possibility of customizing the bridge easier.…”

“…Given the fact that at that date, several drafts of the standard already existed, the architecture of the system, aims for implementing the components defined there. RIWCoS Project, briefly described in [6][7][8] [9], proposes an overall architecture for reconfigurable interoperability in hybrid communication infrastructures that assures service continuity, based on IEEE 802.21 standard. An Interoperability Manager was introduced to provide MIH Function and ensure the cooperation between the component technologies (see Fig.…”
