“…The recursive analysis used for calculating the decision on soft or hard handoff will be chosen as the comparison in our work. Reaz et al (2010) provide an efficient handoff scheme for multiclass networks, and this scheme performed soft handoff for interclass and intraclass mobility in a wireless network and can perform low-loss location management. Hence, we will take this scheme into consideration as our location management method in order to decrease the ratio of packet loss and the delay of handoff.…”

With the popularity of vehicular networks, how to maintain high quality of the seamless live streaming service is a great challenge. In this work, an adaptive seamless live streaming dissemination system for heterogeneous vehicular networks to tackle this challenging issue is presented. First, differential service is presented in this work to ensure that paid users can satisfy the live steaming service. Based on users' service-level agreement, an adaptive bandwidth allocation policy is proposed in this work to attain seamless handoff. In addition, because vehicles enter into the areas of hotspots, we also present a mechanism not only to prevent the insufficient bandwidth in advance, but also to make sure the paid users have higher priority than free users to obtain the seamless streaming service. When an unavoidable congestion occurs, we compress the streaming videos with a Region of Interest approach based on the content and characters of the video in order to maintain the service quality of paid users and reduce the required bandwidth for the streaming services. A series of simulation results show that our mechanism achieves better performance in terms of bandwidth utilization, packet loss ratio, and blocking probability. The capability of self-adaption in volatile real-time vehicular environment assists in the effectiveness and practicability of our proposed approach.

Abstract-Due the complexity of the wireless environments, single technology cannot be efficient to provide demands of mobile users. Hence, in cooperation with heterogeneous wireless technologies, the next generation of wireless systems makes it possible to communicate everywhere. Providing high performance and data rate is what this cooperation has promised to meet. So issues related to the heterogeneity of wireless environment like handover should be addressed. With the appearance of overlapping wireless networks, MNs have to switch their connections between different access technologies having different capabilities and characteristics. In this case, the handover process is more complex and is known as Vertical Handover. In this paper, we focus on the vertical handover management and use an extension of SIP to support vertical handover with bicasting. Delay reduction and SIP signaling messages overhead reduction are the challenges we have tried to improve with our proposed method. To evaluate our proposed method, we use the OPNET Modeler 14.5 and it's Performance for real-time service besides examining the VoIP. Simulation has been performed on UMTS/WLAN networks. The results show that our technique can improve latency and throughput.
