“…In [31,32], the authors have proposed migration techniques specifically for the mobile ad hoc networks. Several other techniques of core migration have been proposed in [33][34][35][36]. In this paper, we bring in the unique perspective of looking at service disruption in addition to tree cost which none of the previous work addresses.…”

“…Due to the characteristics of the DiffServ network, AF1 given the highest priority in the AF class can drop to the lowest priority class when switching networks. A single network may apply a uniform policy, but it is not easy to apply the same policy in a multinetwork, given the different characteristics of Internet Service Providers (ISPs) [ 3 , 4 ]. As seen in Figure 1 , if there are networks A, B and C and packets will be transmitted from A to B and C and networks A and C have the same AF packet priority order, but B simply provides AF, when a packet departing network A enters network B, the packet with AF1 value will lose its value and be provided with service as an AF packet.…”

This study suggests an approach to effective transmission of multimedia content in a rapidly changing Internet environment including smart-phones. Guaranteeing QoS in networks is currently an important research topic. When transmitting Assured Forwarding (AF) packets in a Multi-DiffServ network environment, network A may assign priority in an order AF1, AF2, AF3 and AF4; on the other hand, network B may reverse the order to a priority AF4, AF3, AF2 and AF1. In this case, the AF1 packets that received the best quality of service in network A will receive the lowest in network B, which may result in dropping of packets in network B and vice versa. This study suggests a way to guarantee QoS between hosts by minimizing the loss of AF packet class when one network transmits AF class packets to another network with differing principles. It is expected that QoS guarantees and their experimental value may be utilized as principles which can be applied to various mobile-web environments based on smart-phones.
