“…These works under stand mobility as a particular case of IP multi homing, in which the terminal uses several IP addresses in one or several interfaces and is able to control which IP address is used for each flow. Examples of these approaches can be found using the Shim6 [16] and Mobile SCTP [17] protocols. In [18], authors try to provide a framework for service continuity for IMS based networks using the Shim6 layer to provide IP mobility support.…”

This paper presents TRIM+, an architecture for transparent mobility management with route optimiza tion in IMS based networks. The design of our architecture is based on a previous work referred to as TRIM. TRIM was originally devised to provide transparent mobility support in the IMS, although transpar ency came at the cost of using a suboptimal data path between communicating end points. TRIM+ main tains transparency as a design criterium, and thus end user applications, running at the mobile node and its correspondent communication peers, are unaware of mobility management procedures. Additionally, the proposed design defines a set of route optimization procedures, allowing compliant devices to use the optimal data path for media communications. Furthermore, TRIM+ addresses packet loss management in scenarios where the media path cannot be maintained during the handover of the MN. To this end, our architecture enables the MN to request buffering capacity in its home network to temporarily store incoming media traffic during the handover, which would otherwise be dropped. This mechanism, as well as route optimization procedures, are executed transparently to the end user applications running at the communicating end points. As a proof of concept, we have implemented a software prototype of the TRIM+ architecture, deploying it over a real IMS testbed. By means of a set of experiments, we have val idated the mechanisms proposed in this paper, considering both UDP and TCP user traffic.

“…The management of mobility in the transport layer is made exclusively by Stream Control Transmission Protocol (SCTP) [8] and its extension: Dynamic Address Reconfiguration (DAR) [9]. SCTP extended with DAR constitute Mobile SCTP (MSCTP) [10] [11] [12].…”

“…The CN sends at this moment all the messages to the new IP address of MS via the foreign network. And finally, when the MS leave definitively the coverage area of the home network, it informs the CN to delete the first IP address of the association, which the CN confirms with an ACK [10] [11] [12]. To use MSCTP, the only requirement is that the both endpoints should implement MSCTP protocol.…”

“…It is noted that this slight under-estimation can be helpful to prevent the excessive data transmission when the new path is in congestion. From these empirical results, we can see that the modified WBEST Now, we will compare the performance of the proposed congestion control scheme with the two existing schemes: the normal mSCTP (conservative) scheme [4] and the Cellular SCTP (aggressive) scheme [11]. In particular, we consider Cellular SCTP (C-SCTP) without bicasting mechanism, since the main purpose of this paper is to analyze the performance of the congestion control schemes during handover.…”

“…It is noted that the Stream Control Transmission Protocol (SCTP) [2] was proposed to support IP handover in the transport layer with the help of the multi-homing feature and dynamic address reconfiguration extension [3], which is called mobile SCTP (mSCTP) [4]. mSCTP handover allows a mobile node (MN) to dynamically add a new IP address or delete an old IP address to or from the current SCTP association, as MN moves across different IP networks.…”

This paper proposes a new congestion control scheme of mobile Stream Control Transmission Protocol (mSCTP) for vertical handover across heterogeneous wireless/mobile networks. The proposed scheme is based on the estimation of available bandwidths in the underlying network as a cross-layer optimization approach. For congestion control of mSCTP, the initial congestion window size of the new primary path is adaptively configured, depending on the available bandwidth of the new link that a mobile node moves into. By ns-2 simulation, the proposed scheme is compared with the existing congestion control schemes in the throughput perspective. From the numerical results, we can see that the proposed mSCTP congestion control scheme could give better performance than the existing schemes in the wireless networks with an amount of background traffic.
