Abstract:Real-time packet based services such as Voice over IP (VoIP) have stringent packet delivery requirements, characterized by very low packet loss (in the order of 1% -2%) and tight air-interface delay budgets in the order of tens of milliseconds (ms). In the context of IEEE 802.16e, VoIP service raises additional challenges since the MAP overhead, and hence the required resources dedicated to the control traffic, can grow very large in the presence of multiple simultaneous connections, limiting the amount of res… Show more
