ABSTRACT: An important challenge for All-IP wireless networks is the development of solutions that jointly provide QoS and mobility. Several approaches have been proposed to support a fast handoff simultaneously with a fast re-reservation of resources. These approaches however do not match the real-time requirements. Transparent QoS-aware mobile IP fast authentication protocol (T-QoMIFA) is proposed to satisfy the requirements of delay sensitive applications. T-QoMIFA integrates ReSource reserVation Protocol (RSVP) with MIFA through introducing a new RSVP object called " mobility object " used to carry the mobility Information. In this paper we present an analytical model to evaluate the performance of T-QoMIFA compared to Hierarchical Mobile RSVP (HMRSVP) with respect to the sum of handoff latency and reservation time, the expected number of dropped packets and the expected number of the best-effort packets sent while reservation is in progress. Movement patterns and dropping of control messages are taken into account in our analysis. Our study shows that T-QoMIFA clearly outperforms HMRSVP. T-QoMIFA achieves a fast handoff and a fast re-reservation of resources. The dropped and the best-effort packets are minimized using T-QoMIFA. Therefore, T-QoMIFA is an efficient protocol even if control messages have been dropped.

ABSTRACT: A main challenge in all-IP networks is how to deliver real-time services with suitable QoS while moving in the network. Mobile IP (MIP) is the standard mobility management protocol in IP system. However, MIP is unsuitable for QoS-sensitive applications. Mobile IP fast authentication protocol (MIFA) is proposed to shorten the handoff time. Although, MIFA presents a good solution to provide seamless mobility, it supports no QoS. Resource reservation protocol (RSVP) is a known IP-based reservation mechanism. It is widely used to reserve resources on a certain path of routers throughout the Internet. However, RSVP does not notice the mobility of mobile devices. In this paper we propose a new QoS-enabled mobility management framework for IP-based networks. In this framework we integrate MIFA with RSVP to support fast QoS re-reservation during and after the movement. We extend RSVP by adding a new object called mobility object. MIFA messages are encapsulated in this object. Our proposal enables the correspondent node to use the old path while the new one is in progress. Thus, the time required to establish a new reservation is hidden from the application. Additionally, our proposal allows simple network architectures and doesn't introduce any new entities to the network

ABSTRACT: 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.
