Reducing Handover Delay by Location Management in Mobile WiMAX Multicast and Broadcast Services

Mobile Worldwide Interoperability for Microwave Access (WiMAX) includes a multimedia Multicast/Broadcast Service (MBS), but delay-sensitive applications such as video and audio streaming require the combination of efficient handling of wireless-link bandwidth and reduced handover delays, which remains a challenge. To reduce the handover delay in the MBS, the IEEE 802.16e standard introduces an MBS zone, which is a group of base stations that are broadcasting the same multicast packets. However, this raises the MBS traffic load on Mobile WiMAX networks, particularly the wireless part.
