On Efficient And Scalable Support Of Continuous Queries In Mobile Peer-To-Peer Environments

Technology Used: Java IEEE 2011 An efficient and scalable query processing framework for continuous spatial queries in mobile peer-to-peer (P2P) environment is proposed. Due to the limitations in mobile P2P environments, for example, user mobility, limited battery power, limited communication range, and scarce communication bandwidth, it is costly to maintain the exact answer of continuous [...]

Dynamic Conflict-Free Transmission Scheduling for Sensor Network Queries

Technology Used: Java IEEE 2011 Download IEEE Projects 2011 Basepaper ABSTRACT With the emergence of high data rate sensor network applications, there is an increasing demand for high-performance query services. To meet this challenge, we propose Dynamic Conflict-free Query Scheduling (DCQS), a novel scheduling technique for queries in wireless sensor networks. In contrast to earlier [...]

Fast Detection of Mobile Replica Node Attacks in Wireless Sensor Networks Using Sequential Hypothesis Testing

Technology Used: Java IEEE 2011 Download IEEE Projects 2011 Basepaper ABSTRACT Due to the unattended nature of wireless sensor networks, an adversary can capture and compromise sensor nodes, make replicas of them, and then mount a variety of attacks with these replicas. These replica node attacks are dangerous because they allow the attacker to leverage [...]

A Privacy-Preserving Location Monitoring System for Wireless Sensor Networks

Technology Used: Java / J2EE IEEE 2011 Download IEEE Projects 2011 Basepaper Monitoring personal locations with a potentially untrusted server poses privacy threats to the monitored individuals. To this end, we propose a privacy-preserving location monitoring system for wireless sensor networks. In our system, we design two in-network location anonymization algorithms, namely, resource and quality-aware [...]

Localized Multicast Efficient and Distributed Replica Detection in Large-Scale Sensor Networks

Technology Used: Dot Net IEEE 2010 Due to the poor physical protection of sensor nodes, it is generally assumed that an adversary can capture and compromise a small number of sensors in the network. In a node replication attack, an adversary can take advantage of the credentials of a compromised node to surreptitiously introduce replicas [...]

VEBEK Virtual Energy-Based Encryption And Keying For Wireless Sensor Networks

Technology Used: Dot Net IEEE 2010 Designing cost-efficient, secure network protocols for Wireless Sensor Networks (WSNs) is a challenging problem because sensors are resource-limited wireless devices. Since the communication cost is the most dominant factor in a sensor’s energy consumption, we introduce an energy-efficient Virtual Energy-Based Encryption and Keying (VEBEK) scheme for WSNs that significantly [...]

Secure Data Collection in Wireless Sensor Networks Using Randomized Dispersive Routes

Technology Used: Dot Net IEEE 2010 Compromised-node and denial-of-service are two key attacks in wireless sensor networks (WSNs). In this paper, we study routing mechanisms that circumvent (bypass) black holes formed by these attacks. We argue that existing multi-path routing approaches are vulnerable to such attacks, mainly due to their deterministic nature. So once an [...]
