Label Switching (MPLS) is an emerging technology that aims to address many of the existing issues associated with packet forwarding in today's Internetworking environment. It provides a method of forwarding packets at a high rate of speed by combining the speed and performance of Layer 2 with the scalability and IP intelligence of Layer 3. In a traditional IP (Internet Protocol) routing network...

In recent times, there have been many advances in the field of information theory and wireless sensor network (WSN) technologies. Network coding is a new paradigm in data transport and promises to change many aspects of WSN. In this paper, we introduce an analytical framework to study the performance of network coding based multipath routing, and proposes a Network Coding based Multipath Routin...

We present a novel geographical routing scheme for spontaneous wireless mesh networks. Greedy geographical routing has many advantages, but suffers from packet losses occurring at the border of voids. In this paper, we propose a flexible greedy routing scheme that can be adapted to any variant of geographical routing and works for any connectivity graph, not necessarily Unit Disk Graphs. The id...

The packet routing problem, i.e., the problem to send a given set of unit-size packets through a network on time, belongs to one of the most fundamental routing problems with important practical applications, e.g., in traffic routing, parallel computing, and the design of communication protocols. The problem involves critical routing and scheduling decisions. One has to determine a suitable (sh...

Pure all-optical packet-switched networks in which both header processing and packet routing are carried out in the optical domain overcome the bandwidth bottlenecks of optoelectronic conversions and therefore are expected to meet the needs of next generation high speed networks. Due to the limited capabilities of available optical logic devices, realizations of pure all-optical packet-switched...

Mobile Ad-Hoc Network (MANET) is a wireless network without infrastructure. Self-configurability and easy deployment feature of the MANET resulted in numerous applications in this modern era. Efficient routing protocols will make MANETs reliable. The open and dynamic operational environment of MANET makes it vulnerable to various network attacks. A common type of attacks targets at the underlyi...
