Performance evaluation of the push-mode-multicast based candidate access router discovery (PMM CARD)

摘要: In order to provide nomadic users with QoS-enabled services, advanced mobility management will prove be of fundamental importance in the future Internet. It has been widely recognized that basic Mobile IPv4/v6 protocols could perform poorly, especially QoS-demanding applications. One main steps achieve seamless handover is quick discovery surrounding wireless coverage at each access router (AR), i.e., IP addresses and service capabilities (SCs) candidate routers (CARs) hand over to. The rapid knowledge allows mobile nodes (MNs) speed-up process, whereas information about SCs are important for selection most appropriate (target router, TAR) among set CARs, according a given criterion (e.g., load balancing).In this paper, we first describe (CARD) solutions proposed within framework IETF SEAMOBY WG, which inspired research field. Then, propose distributed push-mode-multicast based CARD (PMM CARD) approach compare it proposals. novelty our solution use push-mode multicast transmissions, enables an efficient distribution network, together significant reduction latency due explicit queries remote entity.Then, develop theoretical model compute signaling burden associated different solutions. Our analysis shows that, even though amount required implement all approaches generally low, gives certain improvement proposals terms average load. addition, results obtained by simulation campaign show effectiveness PMM time needed ARs discover coverage.
