“…Das proposed a similar scheme that only makes advance reservations when the MN is near the edge of the current cell [8]. In this scheme, the BS continually measures the signal strength from the MN.…”

“…The current BS then makes an advance reservation in the cell with the strongest signal and the two cells adjacent to that. Das states that to ensure seamless QoS, the width of the peripheral region at the edge of the cell should be such that the least possible time to traverse the region is greater than the time to set up a reservation [8].…”

Future wireless cellular networks will be Internet Protocol (IP) based. Users of wireless devices in these networks will expect to run real-time applications that require guarantees of Quality of Service (QoS). Such a user will expect the same seamless QoS that he would receive if he were running real-time applications on a wired network. Achieving seamless QoS in a mobile environment implies that a reservation should be re-established at the new Base Station (BS) before hand-over occurs. However, making these advance reservations is wasteful of valuable bandwidth in the wireless network. This paper proposes a protocol, called the Mobility Monitoring Based Advance Reservation Protocol (M²BARP), which aims to reduce the bandwidth overhead of making advance reservations. The protocol makes use of information about a Mobile Node's (MN) mobility to make a single advance reservation when the MN is about to hand-over. Unlike previous work, M²BARP takes advantage of overlapping cells to help to provide a more seamless QoS by reducing the number of calls dropped at handover.

Abstract-We consider the problem of dynamically assigning application sessions of mobile users or user groups to service points. Such assignments must balance the trade-off between two conflicting goals. On the one hand, we would like to connect a user to the closest server in order to reduce network costs and service latencies. On the other hand, we would like to minimize the number of costly session migrations, or handoffs, between service points. We tackle this problem using two approaches. First, we employ algorithmic online optimization to obtain algorithms whose worst-case performance is within a factor of the optimal. Next, we extend them with opportunistic heuristics that achieve near-optimal practical average performance and scalability. We conduct case studies of two settings where such algorithms are required: wireless mesh networks with mobile users and wide-area groupware applications with or without mobility.
