P-MIP: Paging Extensions for Mobile IP

As the number of Mobile IP users grows, so will the signalling overhead associated with Internet mobility management in the core IP network. This presents a significant challenge to Mobile IP as the number of mobile devices scale-up. In cellular networks, registration and paging techniques are used to minimize the signalling overhead and optimize the mobility management performance. Currently, Mobile IP supports registration but not paging. In this paper, we argue that Mobile IP should be extended to support paging to improve the scalability of the protocol to handle large populations of mobile devices. To address this, we introduce P-MIP, a set of simple paging extensions for Mobile IP, and discuss the construction of paging areas, movement detection, registration, paging and data handling. We present analysis and simulation results for Mobile IP with and without paging extensions, and show that P-MIP can scale well supporting large numbers of mobile devices with reduced signalling under a wide variety of system conditions.

Transmission in mobile cloudlet systems with intermittent connectivity in emergency areas

The recent development of Mobile Cloud Computing has helped in solving numerous real-life problems. The rate of growth of mobile devices has been increasing at a very high pace. Mobile devices have made substantial contributions in managing emergency situations. Owing to the mobility of mobile devices, cloudlets, and their intermittent connectivity, it may become very difficult to handle emergency situations. To address this problem, a transmission model is proposed for mobile cloudlet systems, where a mobile device is used to designate a cloudlet by using the Borda scores Method and the mobile device can offload a part of its application to this cloudlet. The simulation results demonstrated that the proposed work makes a significant comtribution toward alleviating the problems associated with emergency situations.     

Minimizing the Handoff Latency in Ad-Hoc Networks When Streaming Media to Mobile Devices

The number of mobile devices connecting to networks independently of a fixed point of attachment is increasing. These wireless networks differ in bandwidth, size and location of the coverage area, access costs and network characteristics. Mobile multimedia devices such as PDA's, palmtops and laptops will also vary greatly in size and processing power. The common denominator however, is that all these devices will require the optimal delivery of networked multimedia data.One interesting problem is the delay imposed upon mobile receivers when switching between wireless cells. We provide a solution to this in the form of an extension of Mobile IP's hand-off algorithm. Our solution involves the exploitation of mobility prediction to predict a mobile terminal's future location based on its previous history (i.e., the last cell that it has been in) and for the media stream to be already present and cached by next cells base station ready for receiving by the mobile device.We cater specifically for continuous media applications, which can be especially effected by severe degradation in quality due to movement between cells. We present the results of a series of simulations of the Mobile IP++ protocol, which demonstrate the effectiveness of the ad-hoc protocol when mobile hosts move in predictable patterns between cells.

Resource Management Strategies for the Mobile Web

The success of the Mobile Web is driven by the combination of novel Web-based services with the diffusion of advanced mobile devices that require personalization, location-awareness and content adaptation. The evolutionary trend of the Mobile Web workload places unprecedented strains on the server infrastructure of the content provider at the level of computational and storage capacity, to the extent that the technological improvements at the server and client level may be insufficient to face some resource requirements of the future Mobile Web scenario. This paper presents a twofold contribution. We identify some performance bottlenecks that can limit the performance of future Mobile Web, and we propose and evaluate novel resource management strategies. They aim to address computational requirements through a pre-adaptation of the most popular resources even in the presence of irregular access patterns and short resource lifespan that will characterize the future Mobile Web. We investigate a large space of alternative workload scenarios. Our analysis allows to identify when the proposed resource management strategies are able to satisfy the computational requirements of future Mobile Web, and even some conditions where further research is necessary.
