The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the co...

The number of mobile computers is increasing at a phenomenal rate, and efficient support for mobility will make a decisive difference to the Internet's future performance. This, along with the growing importance of the Internet and the web indicates the need to pay attention to supporting mobility. Mobile IPv6 (MIPv6) is a protocol to deal with mobility for the next generation Internet (IPv6). ...

Performance evaluation of protocols and mechanisms in wireless networks require a good representation of client mobility. The number of mobility models has been developed, to emulate the changes of location in time of mobile wireless devices in communication networks, such as e.g. mobile phones, tablets, netbooks, palmtops. Mobility models are used to verify the protocols and algorithms develop...

Agent based micro-mobility protocols such as Hierarchical Mobile IPv6 deploy special IPv6 nodes called Mobility Agents that act as an anchor point between the Mobile Node and the Home Agent providing localized mobility support. The location and the number of MAs deployed within the network can affect the performance of the protocol. This paper deals with the problem of Mobility Agent (MA) locat...

The 5th generation mobile and wireless communication systems are expected to accommodate exploding traffic, increasing number of devices, and heterogeneous applications driven by proliferation of IoT and M2M technologies. The centralized mobility management architecture in a current mobile core network cannot satisfy these emerging requirements. In this paper, we introduce novel architecture of...

This seminar deliberates the challenges of using small, low-cost robotic nodes with limited processing capabilities in collaborative search and rescue. We have attempted to employ selfdesigned mobility models suited to the mobility patterns of such nodes. Mobility models have traditionally been used to represent movement patterns in Ad-hoc network devices like cell phones, laptops, etc. The stu...

A Mobile Ad-Hoc Network (MANET) is a selfconfiguring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. In this paper, we have studied the effects of various mobility models on the performance of two routing protocols Dynamic Source Routing (DSRReactive Protocol) and Destination-Sequenced DistanceVector (DSDV-Proactive P...

Existing generative mobility models, used to produce mobility data for simulated agents in, e.g., wireless network simulations, suffer from a number of limitations. Most significantly, existing models are not representative of actual human movement. We introduce a new mobility model based on state-of-the-art work in understanding pedestrian mobility patterns in urban areas, known as Space Synta...

Abstract The convergence of wireless and Internet Protocol (IP) has led to the need for IP to handle mobility. The Mobile IP protocol was developed to facilitate IP mobility. However, it has a number of shortcomings...

To realize the full potential of mobile multimedia, mobility protocols are needed to handle situations when nodes move while in a multimedia session. Many mobility protocols have been proposed for IP-based networks. In some important cases in using these mobility protocols such as mobile IPv6 with route optimization, a problem can arise when both nodes are mobile and move simultaneously. The pr...
