ABSTRACT A mobile ad-hoc network (MANET) consists of wireless mobile hosts (nodes) that communicate with each other over wireless link, in the absence of a fixed infrastructure. Routes between two hosts in MANET may consists of hops through other hosts in the network, due to the limitation of broadcasting range of each host Movement of hosts... Continue Reading

ABSTRACT Active networking is the emerging technology that will provide new network environment where lots of potential applications can be enhanced and developed. Current IP network is somehow good at simple packet forwarding, but it desperately needs some flexibility to support QoS and has to meets some restraint in certain environment. Active...

ABSTRACT On-demand routing protocols use route caches to make routing decisions. Due to mobility, cached routes easily become stale. To address the cache staleness issue, prior work in DSR used heuristics with ad hoc parameters to predict the lifetime of a link or a route. However, heuristics cannot accurately estimate timeouts because topology... Continue Reading

A huge number of studies have been done supporting seamless mobility networks and mobile technologies over the years.  The recent innovations in mobile technologies have unveiled another revolution from the static architectural approach for client-server network relationships to more dynamic, and even mobile approaches. Due to the special... Continue Reading

ABSTRACT IP multicast is facing a slow take-off although it has been a hotly debated topic for more than a decade. Many reasons are responsible for this status. Hence, the Internet is likely to be organized with both unicast and multicast enabled networks. Thus, it is of utmost importance to design protocols that allow the progressive deployment...

ABSTRACT The Transmission Control Protocol (TCP) wad designed to provide reliable end-to-end delivery of data over unreliable networks. In practice most TCP deployments have been carefully designed in the context of wired networks. Ignoring the properties of wireless Ad hoc Network can lead to TCP implementations with poor performance. In order to... Continue Reading

Abstract A Mobile Ad-hoc Data Network (MADNET) is a self-configuring, infrastructure-less network of mobile devices (nodes) where nodes communicate with each other using multi-hop wireless links. Node failures and arbitrary movement of nodes at higher node velocity break the routes and lead to the frequent operation of rebuilding routes that... Continue Reading

Abstract The modern-day automobile is no longer just an analog and mechanical entity. Currently, the most basic of vehicular functions have been computerized. The dedicated hardware assigned to these tasks are electronic control units (ECU). Automobiles consist of a number of ECUs networked together to ensure proper functioning of the vehicle. The...

ABSTRACT Multicast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack... Continue Reading
