TCP Performance in Ad Hoc Networks [PDF]

open access: yes, 2000
Ad hoc networks are mobile wireless networks which do not have any kind of fixed infrastructure. The routing layer in an ad hoc network ties the network together into a seamless entity and provide transparent services to higher layer protocols.

A Review of routing protocols for mobile cognitive radio ad hoc networks [PDF]

open access: yesarXiv, 2012
Ad hoc network is a collection of wireless mobile nodes that dynamically form a temporary network without the use of any existing network infrastructure or centralized administration. A cognitive radio is a radio that can change its transmitter parameters based on interaction with the environment in which it operates.

Hierarchical Design Based Intrusion Detection System For Wireless Ad hoc Network

open access: yes, 2010
In recent years, wireless ad hoc sensor network becomes popular both in civil and military jobs. However, security is one of the significant challenges for sensor network because of their deployment in open and unprotected environment.

An Effective Black Hole Attack Detection Mechanism using Permutation Based Acknowledgement in MANET [PDF]

open access: yesarXiv, 2014
With the evolution of wireless technology and use of mobile devices, Mobile Ad-hoc Network has become popular among researchers to explore. A mobile ad-hoc network (MANET) is a self-configuring network of mobile routers (and associated hosts) connected by wireless links.

Determining design parameters for Ad-hoc wirless sensor networks. [PDF]

open access: yes, 2003
This paper considers the design of wireless sensor networks in which a set of smart battery-powered sensor nodes cooperatively form an ad hoc communications network for monitoring and control applications. The paper examines ways of extending the life of

Evaluating Wireless Reactive Routing Protocols with Linear Programming Model for Wireless Ad-hoc Networks [PDF]

open access: yesJ. Basic. Appl. Sci. Res., 3(1)1170-1181, 2013, 2013
In Wireless Ad-hoc Networks, nodes are free to move randomly and organize themselves arbitrarily, thus topology may change quickly and capriciously. In Mobile Ad-hoc NETworks, specially Wireless Multi-hop Networks provide users with facility of quick communication.

The Effect of Eavesdropping and Wormhole Attacks on Mobile Ad Hoc Network [PDF]

open access: yes, 2009
Security has become the main concern to grant protected communication between mobile nodes in an unfriendly environment. Wireless Ad Hoc network might be unprotected against attacks by malicious nodes.

Performance Evaluation of on demand and Table driven Protocol for Wireless Ad hoc Network [PDF]

open access: yesarXiv, 2012
Mobile Adhoc Network is a wireless network without infrastructure.It is a kind of wireless adhoc network,and is a self configuring network of mobile routers connected by wireless links.The routers are free to move randomly and organize themselves arbitrarily,thus the network's wireless topology may change rapidly and unpredictably.

Can place‐based crime prevention impacts be sustained over long durations? 11‐Year follow‐up of a quasi‐experimental evaluation of a CCTV project

open access: yesCriminology &Public Policy, EarlyView.
Abstract Research summary A long‐standing critique of place‐based crime prevention interventions has been that any reductions in crime are often short‐lived. If researchers do not carry out longer‐duration follow‐ups, we cannot know for sure if the effects of these interventions will persist, decay, or even strengthen.
