The Impact of Channel Randomness on Coverage and Connectivity of Ad Hoc and Sensor Networks
Abstract-- In this paper, we first present an analytical procedure for the computation of the node isolation probability and coverage in an ad hoc network in the presence of channe...

Local Detection of Selfish Routing Behavior in Ad Hoc Networks
Reputation mechanisms for detecting and punishing free-riders in ad hoc networks depend on the local detection of selfish behavior. Although naive selfish strategies based on drop...

GKMPAN: An Efficient Group Rekeying Scheme for Secure Multicast in Ad-Hoc Networks
We present GKMPAN, an efficient and scalable group rekeying protocol for secure multicast in ad hoc networks. Our protocol exploits the property of ad hoc networks that each membe...

Dynamic Connectivity in ALOHA Ad Hoc Networks
We consider an ad hoc network which uses multihop routing and slotted ALOHA for its MAC contention. We show that the minimum time required for a packet to reach the destination fr...

A Distributed Trust Management Framework for Detecting Malicious Packet Dropping Nodes in a Mobile Ad Hoc Network
In a multi-hop mobile ad hoc network (MANET) mobile nodes communicate with each other forming a cooperative radio network. Security remains a major challenge for these networks du...

Cognitive networks achieve throughput scaling of a homogeneous network
We study two distinct, but overlapping, networks which operate at the same time, space and frequency. The first network consists of

Reputation-Based Attack-Resistant Cooperation Stimulation (RACS) For Mobile Ad hoc Networks
In mobile ad hoc networks (MANET), nodes usually belong to different authorities and pursue different goals. In order to maximize their own performance, nodes in such networks ten...
