STARS: A Statistical Traffic Pattern Discovery System for MANETs

STARS: A Statistical Traffic Pattern Discovery System for MANETs ABSTRACT Many anonymity enhancing techniques have been proposed based on packet encryption to protect the communication anonymity of mobile ad hoc networks (MANETs). However, in this paper, we show that MANETs are still vulnerable under passive statistical traffic analysis attacks. To demonstrate how to discover the [...]

Defending Against Collaborative Attacks by Malicious Nodes in MANETs: A Cooperative Bait Detection Approach

Defending Against Collaborative Attacks by Malicious Nodes in MANETs: A Cooperative Bait Detection Approach ABSTRACT In mobile ad hoc networks (MANETs), a primary requirement for the establishment of communication among nodes is that nodes should cooperate with each other. In the presence of malevolent nodes, this requirement may lead to serious security concerns; for instance, [...]

VSPN: VANET-Based Secure and Privacy-Preserving Navigation

VSPN: VANET-Based Secure and Privacy-Preserving Navigation ABSTRACT In this paper, we propose a navigation scheme that utilizes the online road information collected by a vehicular ad hoc network (VANET) to guide the drivers to desired destinations in a real-time and distributed manner. The proposed scheme has the advantage of using real-time road conditions to compute [...]

PSR: A Lightweight Proactive Source Routing Protocol For Mobile Ad Hoc Networks

PSR: A Lightweight Proactive Source Routing Protocol For Mobile Ad Hoc Networks ABSTRACT Opportunistic data forwarding has drawn much attention in the research community of multihop wireless networking, with most research conducted for stationary wireless networks. One of the reasons why opportunistic data forwarding has not been widely utilized in mobile ad hoc networks (MANETs) [...]

AASR: Authenticated Anonymous Secure Routing for MANETs in Adversarial Environments

AASR: Authenticated Anonymous Secure Routing for MANETs in Adversarial Environments ABSTRACT Anonymous communications are important for many applications of the mobile ad hoc networks (MANETs) deployed in adversary environments. A major requirement on the network is to provide unidentifiability and unlinkability for mobile nodes and their traffics. Although a number of anonymous secure routing protocols [...]

Sleep Scheduling for Geographic Routing in Duty-Cycled Mobile Sensor Networks

Sleep Scheduling for Geographic Routing in Duty-Cycled Mobile Sensor Networks ABSTRACT Recently, the research focus on geographic routing, a promising routing scheme in wireless sensor networks (WSNs), is shifting toward duty-cycled WSNs in which sensors are sleep scheduled to reduce energy consumption. However, except the connected-k neighborhood (CKN) sleep scheduling algorithm and the geographic routing [...]
