Security in wireless ad hoc network
International Journal of Internet Protocol Technology, 2017The mobile ad hoc network is open medium, easy to deploy and free of the centralised control network. But these features of mobile ad hoc network come along with security attacks, such as black hole attack and grey hole attack. In black hole attack malicious node degrades security and performance of network.

Coverage in wireless ad-hoc sensor networks [PDF]
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003 Sensor networks pose a number of challenging conceptual and optimization problems such as location, deployment, and tracking. One of the fundamental problems in sensor networks is the calculation of the coverage. In Meguerdichian et al. (2001), it is assumed that the sensor has uniform sensing ability.

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 ...

Flooding in wireless ad hoc networks
Computer Communications, 2001In 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

Wireless Agents in Ad Hoc Networks
2003With 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 ...

NONACK in wireless ad hoc network
2014 Innovative Applications of Computational Intelligence on Power, Energy and Controls with their impact on Humanity (CIPECH), 2014A wireless ad hoc sensor network (WSN) is made up of a number of geographically spread apart sensors each with a reasonable amount of signal processing and data networking ability coupled with wireless communication. One of the major challenges wireless sensor networks face today is security.

Ad Hoc Networks and the Wireless Internet
2003Those 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 ...

Wireless Mobile Ad Hoc Networks
2011NS2 classifies communication networks into three main categories. First, wired networks are characterized by wired communication links. Chapter 7 shows a simple form of the wired links called SimpleLinks which can be used to connect regular Node discussed in Chap. 6.

Wireless ad hoc nanoscale networking
IEEE Wireless Communications, 2009Wireless ad hoc communication on the nanoscale will require thinking outside of the traditional radio spectrum. New applications will utilize new forms of wireless communication channels. For example, nanoscale communication will enable precise mechanisms for directly interacting with cells in vivo.
