MaISAM: A New Fast QoS Aware Mobility Management Protocol for “ALLIP” Networks

Several solutions have been proposed to couple QoS with mobility management in a way that can satisfy the real-time requirements. The most of these solutions depend on RSVP which suffers from many drawbacks. "Next Step In Signaling" protocol suite (NSIS) presents a new promised framework that can be used to signal for different QoS models and cover the drawbacks of RSVP. This paper proposes a new solution named MalSAM (Mobility management aware Next Step In Signaling for "All-IP" Mobile communication networks). MalSAM supports a fast and a smooth handoff simultaneously with a fast reservation of resources during and after the handover. It integrates the Mobile IP Fast Authentication protocol (MIFA) with QoS-NSIS Signaling Layer Protocol (QoS-NSLP). This is achieved by adding a new object to accommodate MIFA messages. The main advantages of MalSAM are its simple network architecture without introducing new entities and its fast handover and fast resources reservation.
