Growth of wireless ad hoc networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
The utility of a node in an energy-limited wireless ad hoc network is defined as a positive linear function of the number of bits that the node sends as a source and the number of bits that it receives as a destination. First, we show that under the one-to-one traffic model in which every node wants to send traffic to a randomly chosen destination node,

Routing in wireless ad hoc networks

International Journal of Internet Protocol Technology, 2012
A routing strategy that finds a path to be followed by packets from a source node to a destination node used in traditional wired networks cannot be directly applied in ad hoc wireless networks due to their highly dynamic topology, absence of established infrastructure for centralised administration, bandwidth constrained wireless links, and energy ...

Security in Wireless Ad Hoc Networks [PDF]

, 2009
Operating in open and shared media, wireless communication is inherently less secure than wired communication. Even worse, mobile wireless devices usually have limited resources, such as bandwidth, storage space, processing capability, and energy, which makes security enforcement hard.

Wireless Ad Hoc Networking

2005
Mobile ad hoc networks represent a new form of communication consisting of mobile wireless terminals (e.g., handset, PDAs, notebooks). These type of networks are wireless multi-hop packet networks without any fixed infrastructure and centralized administration, in contrast to today’s wireless communications, which is based on a fixed, pre-established ...

Flooding in wireless ad hoc networks

Computer Communications, 2001
In an ad hoc network, each host assumes the role of a router and relays packets toward final destinations. This paper studies efficient routing mechanisms for packet flooding in ad hoc wireless networks. Because a packet is broadcast to all neighboring nodes, the optimality criteria of wireless network routing are different from that of the wired ...

On the scalability of ad hoc wireless networks [PDF]

, 2008
This dissertation considers the problem of scaling ad hoc wireless networks now being applied to urban mesh and sensor networks scenarios. Ad hoc networks involve multi-hop communication which has inherent scaling problems in that throughput per node drops as the square root of the number of nodes in the network. We investigate mechanisms for improving

Ad Hoc Wireless Networks

2004
Ad hoc networks offer a radical alternative to existing cellular and fixed networks for providing communications. These networks form on the fly from the communications devices themselves without needing any infrastructure or centralised control. Devices communicate directly with each other and by forming chains of transceivers they relay information ...

Wireless Agents in Ad Hoc Networks

2003
With the current trend toward ubiquitous computing comes wireless devices capable of direct, peer-to-peer communication. Such devices will be capable of forming the nodes of ad hoc networks. In the near future, it is expected that ad hoc networks will be saturated with heterogeneous hardware and software requiring mechanisms to facilitate ...

Ad Hoc Networks and the Wireless Internet

2003
Those of you who are Star Trek fans, or have ever watched any movie or TV episode from this series, must have noticed total absence of wires in their universe: crew member communicate by touching their Starfleet badges, doctors diagnose (and further more cure) patients simple by moving sophisticated instruments (so called “tricorders”) over patients ...
