As the existence of diverse network technologies, QoS signaling is needed to guarantee the end-to-end QoS for users in complex network environment. Compared with the previous QoS signaling with resource reservation, NSIS (next steps in signaling) proposed by IETF is better in flexibility and scalability. This paper proposes a new mobility-aware scheme for QoS NSLP (NSIS signaling layer protocol) in...
In order to avoid the problem caused by single point of failure of the root AAA (authentication, authorization, and accounting) server in hierarchical AAA mobility management (HAMM), a novel robust fault tolerant scheme for hierarchical AAA (RFT-HA) is proposed in Mobile IPv6. In this scheme, the period of detecting the root AAA server's (RAAAS) failure is decreased by adopting ICMPv6 and Diameter...
The paper concentrates on the trends of integrating cellular network with multi-hop network. A new adaptive mode select mechanism which comprises three parts has been proposed. Based on the normalized reference zone calculated by the mechanism, mode selection between multi-hop mode and cellular mode can be executed. Based on simplified simulation analysis, it is verified that the algorithm we proposed...
