“…In [4], an advanced agent-based architecture to provide guaranteed quality to the Mobile users in a WLAN is presented for a VoD (Video on Demand) Service. In it, the Access Points manage the user's mobility (handoff) and implement the management policies of the QoS (reservation, allocation and distribution of the bandwidth).…”

One of the multimedia services offered by the campus network of the Polytechnic University of Valencia is TV over IP. This service works well in the devices connected directly to the wired network but we have detected some problems when the receivers access to the campus network through wireless IEEE 802.11, especially when devices roam across the Campus. In this paper we propose and evaluate a server-based solution to minimize the packet loss and reduce the lack of service when the mobile devices roam from an Access Point to another Access Point in the wireless network. This solution uses a location system to modify the behaviour of standard multicasting protocols in order to get a near-seamless multicast WiFi roaming.

“…Media and protocol adaptations are proposed in [21] to meet channel conditions. In [22] the authors develop a distributed system to improve streaming services performance on user mobility cases. This system predicts user handoffs and controls the state of the streaming sessions to reduce packet loss and negative effects.…”

DSMeM Streaming: distributed system to mitigate the effects of performance anomaly and user mobility on IEEE 802.11 WLANs

On IEEE 802.11 wireless LANs (WLAN) the clients have control over the handoff procedure; a client decides the best AP (access point) to be associated to and when and where to change its association to a new AP. This simple handoff management technique can have negative effects for both static and mobile clients of the same cell, since some wireless clients remain associated with their current AP even when a better AP is reachable. Combined with handoff latencies, this mobility method can have a negative effect on various services with severe restrictions regarding delivery rate and delay. In this paper, a distributed and transparent system that monitors channel conditions, manages user data based on its knowledge and induces client handoffs when a better AP is reachable, is presented. One of the strongest points of the proposed solution is that it can work in currently deployed IEEE 802.11 WLANs without the server, clients or APs having to introduce new software.

“…However, PRIMATE prediction technique is centralized, scarcely scalable, and requires dedicated hardware; in addition, PRIMATE exploits kernel-level client modifications (data interceptors) that should be statically installed at each participant [21]. Another similar research proposal is [22], which describes a proxy-based mobile agent middleware for multimedia streaming: it proposes to employ proxies, called Virtual Servers, to assist roaming users but, differently from MUM, its proxies do not support proactive buffer movement and can be deployed only in intra-domain, ad-hoc, and statically installed network environments with specialized custom APs.…”

Abstract. New deployment scenarios tend to consider the requirement of session continuity for service provisioning, especially multimedia streaming, to limited heterogeneous portable devices roaming among wireless localities. In particular, multimedia streaming should not experience any interruption while clients roam in wired-wireless integrated networks based on the standard besteffort Internet. The paper proposes an application-level middleware approach to proactively overcome Wi-Fi handoff and maintain multimedia session continuity in the wireless Internet by exploiting mobile proxies running on the wired network. Mobile middleware proxies locally support resource-limited clients, avoid packet losses during handoffs, pre-fetch local buffers with multimedia contents before handoff occurrence, and possibly reconfigure/renegotiate ongoing sessions after handoffs. Experimental results show that, notwithstanding the application-level implementation, mobile proxies can avoid streaming discontinuities with good efficiency in wireless-wired integrated networks even if their pro-activity is based on simple and lightweight handoff prediction techniques.
