In this paper we analyze the impact of different ad hoc routing schemes on TCP traffic in multihop ad hoc wireless networks. Our hypothesis is that beyond a certain network size the uncontrolled broadcast transmission of routing messages will seriously degrade the performance of the TCP protocol. We experimentally determine the admissible operation ranges of MANETs where the level of such degra...

The key challenges in mobile Ad Hoc networks are efficient and dynamic routing. An ad hoc routing protocol is a standard that controls the way computing devices route packets in a mobile ad hoc network. The aim of ad hoc routing protocol is to establish correct and efficient route between pair of nodes that requires minimum overhead and bandwidth consumption. A number of ad hoc routing protocol...

This paper investigates combining opportunistic routing techniques with multipath routing for achieving reliability and timeliness in fast-changing network conditions. We present two approaches, WIMOP and DOMR, based on source routing and distributed routing, respectively. Instead of using broadcast packets as in most opportunistic routing work, we use unicast with promiscuous listening so that...

In this paper we present an new ad hoc routing system based upon simple principles regarding the routing strategy and the implementation approach. In the routing area we (re-)introduce the end-to-end principle, letting the communicating end nodes make the decisions concerning the behaviour of intermediate nodes. We adopt a routing strategy that is a mixture of on-demand and pro-active routing i...

In wireless sensor networks (WSNs), it is inappropriate to use conventional unicast routing due the broadcast storm problem and spatial diversity of communication-links. Opportunistic-Routing (OR) benefits low duty-cycled WSNs by prioritizing multiple candidates for each node instead selecting one as in unicast-routing. OR reduces sender waiting time, but also suffers from duplicate packets wak...

Vehicular networks are a promising application of mobile ad hoc networks. In this paper, we introduce an efficient broadcast technique, called CB-S (Cell Broadcast for Streets), for vehicular networks with occlusions such as skyscrapers. In this environment, the road network is fragmented into cells such that nodes in a cell can communicate with any node within a two cell distance. Each mobile ...

Packet-switching WDM ring networks with a hotspot transporting unicast, multicast, and broadcast traffic are important components of high-speed metropolitan area networks. For an arbitrary multicast fanout traffic model with uniform, hotspot destination, and hotspot source packet traffic,we analyze themaximumachievable long-run average packet throughput, which we refer to as multicast capacity,...

For service providers, the ability to offer broadcast IPTV services with high availability and reliability is imperative to remain competitive in an increasingly crowded industry. Meeting customer expectations for a high-quality IPTV service requires a network architecture and routing system that can handle the challenges of delivering broadcast video to millions of users simultaneously while a...

Security has become one of the majorissues for data communication over wired and wireless networks. Different from the past work on the designs of network security algorithms and system infrastructures, we will propose a dynamic broadcast routing algorithm that could randomize delivery paths for data transmission. The algorithm is easy to implement and compatible with popular routing protocols,...

Ad hoc networks lack pre-designated routers and physical infrastructure, which makes routing in these networks a challenging task. To overcome the problems associated with this, virtual backbone has been proposed as the routing infrastructure of ad hoc networks. A well-known and well researched approach for constructing virtual backbone is Connected Dominating Set (CDS). It overcomes the broadc...
