As the future generation networks are envisioned to be heterogeneous in nature, seamless mobility in such networks is an important issue. While IETF work groups have standardized various mobility management protocols, such as Mobile IPv6 (MIPv6), Fast Handovers for Mobile IPv6 (Predictive FMIPv6, and Reactive FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), Proxy Mobile IPv6 (PMIPv6) and Fast Handov...

An ad-hoc network is an aggregation of wireless nodes forming a provisional network without any established infrastructure. To facilitate communication within such network, a routing protocol is used to discover and setup routes between nodes. The goal of the routing protocol is to have an efficient route establishment between a pair of nodes, so that messages can be delivered in a timely manne...

The raise of demanding multimedia content and the increasing number of mobile devices originated a rapid growth of mobile Internet traffic, which is expected to continue increasing with an exponential behavior in the next years. In order to cope with this rapid increase, service providers are already developing new strategies, such as the selective traffic offloading through the wireless local ...

Over the past years a number of IP micro-mobility protocols have been proposed as an extension or complement of Mobile IP. Although the development of these protocols has generated considerable interest in industry and academia, none of them have been widely deployed. The main reason of this lack of real-life usage of micro-mobility proposals is that the RFCs or drafts of these protocols do not...

Mobile IP is a powerful protocol which supports Internet mobility and scales reasonably with the number of users within a system. Due to the high roundtrip delay of the Internet and due to Mobile IP’s control overhead, Mobile IP causes connections of a mobile node to be interrupted for up to 5 seconds for each change of its attachment point to the Internet. This interruption induces TCP to run ...

Opportunistic Routing (OR) is an effective and enhanced routing scheme for wireless multihop environment. OR is an approach that selects a certain number of best forwarders (candidates) at each hop by taking the advantage of the broadcast nature of the wireless medium to reach the destination. When a set of candidates receive the packet, they coordinate with each other to figure out which one h...

In this paper, we describe our efforts leading to the implementation of transparent user mobility in a nextgeneration tactical network for the Polish Armed Forces. We discuss the management architecture, the implementation, and how various problems related to the communication technologies employed by the network have been overcome to achieve the goal. We also comment on how our approach compli...

To support IP-mobility of networks in motion, IETF proposed Network Mobility (NEMO) protocol that uses various signaling messages to ensure connectivity of the mobile nodes with the Internet and to maintain security of ongoing sessions by protecting the binding updates. As the next-generation wireless / mobile network is supposed to be a unified network based on all-IP technology, compounded by...
