Verification of Directed Acyclic Ad Hoc Networks

by Parosh Aziz Abdulla, Mohamed Faouzi Atig, Othmane Rezine
"... Abstract. We study decision problems for parameterized verification of a formal model of ad hoc networks. We consider a model in which the net-work is composed of a set of processes connected to each other through a directed acyclic graph. Vertices of the graph represent states of indi-vidual proces ..."

Ariadne: a secure on-demand routing protocol for ad hoc networks," in

by Yih-Chun Hu , Adrian Perrig , David B Johnson - Proc. 8th ACM International Conf. Mobile Computing Networking , , 2002
"... Abstract An ad hoc network is a group of wireless mobile computers (or nodes), in which individual nodes cooperate by forwarding packets for each other to allow nodes to communicate beyond direct wireless transmission range. Prior research in ad hoc networking has generally studied the routing prob ..."

Intrusion Detection in Wireless Ad-Hoc Networks

by Yongguang Zhang, Wenke Lee , 2000
"... As the recent denial-of-service attacks on several major Internet sites have shown us, no open computer network is immune from intrusions. The wireless ad-hoc network is particularly vulnerable due to its features of open medium, dynamic changing topology, cooperative algorithms, lack of centralized ..."

the vulnerabilities of a wireless ad-hoc network, the reason why we need intrusion detection, and the reason why the current methods cannot be applied directly. We then describe the new intrusion detection and response mechanisms that we are developing for wireless ad-hoc networks. 1. INTRODUCTION A wireless ad-hoc

Energy Aware Routing for Low Energy Ad Hoc Sensor Networks

by Rahul C. Shah, Jan M. Rabaey , 2002
"... The recent interest in sensor networks has led to a number of routing schemes that use the limited resources available at sensor nodes more efficiently. These schemes typically try to find the minimum energy path to optimize energy usage at a node. In this paper we take the view that always using lo ..."

that show increase in network lifetimes of up to 40% over comparable schemes like directed diffusion routing. Nodes also burn energy in a more equitable way across the network ensuring a more graceful degradation of service with time.

Focused crawling: a new approach to topic-specific Web resource discovery

by Soumen Chakrabarti, Martin van den Berg, Byron Dom , 1999
"... The rapid growth of the World-Wide Web poses unprecedented scaling challenges for general-purpose crawlers and search engines. In this paper we describe a new hypertext resource discovery system called a Focused Crawler. The goal of a focused crawler is to selectively seek out pages that are relevan ..."

that are relevant to a pre-defined set of topics. The topics are specified not using keywords, but using exemplary documents. Rather than collecting and indexing all accessible Web documents to be able to answer all possible ad-hoc queries, a focused crawler analyzes its crawl boundary to find the links

Random Waypoint Considered Harmful

by Jungkeun Yoon, Mingyan Liu, Brian Noble , 2003
"... This study examines the random waypoint model widely used in the simulation studies of mobile ad hoc networks. Our findings show that this model fails to provide a steady state in that the average nodal speed consistently decreases over time, and therefore should not be directly used for simulation. ..."

Distributed topology control for power efficient operation in multihop wireless ad hoc networks

by Roger Wattenhofer, Li Li, Paramvir Bahl, Yi-min Wang , 2001
"... Abstract — The topology of wireless multihop ad hoc networks can be controlled by varying the transmission power of each node. We propose a simple distributed algorithm where each node makes local decisions about its transmission power and these local decisions collectively guarantee global connecti ..."

Topology Control in Wireless Ad Hoc and Sensor Networks

by Paolo Santi - ACM Computing Surveys , 2005
"... Topology Control (TC) is one of the most important techniques used in wireless ad hoc and sensor networks to reduce energy consumption (which is essential to extend the network operational time) and radio interference (with a positive effect on the network traffic carrying capacity). The goal of thi ..."

. In this article, we state several problems related to topology control in wireless ad hoc and sensor networks, and we survey state-of-the-art solutions which have been proposed to tackle them. We also outline several directions for further research which we hope will motivate researchers to undertake additional
