ZoneTrust: Fast Zone-Based Node Compromise Detection and Revocation in Wireless Sensor Networks Using Sequential Hypothesis Testing

projects 2012 ZoneTrust: Fast Zone-Based Node Compromise Detection and Revocation in Wireless Sensor Networks Using Sequential Hypothesis Testing- projects 2012 – Dependable and Secure computing Due to the unattended nature of wireless sensor networks, an adversary can physically capture and compromise sensor nodes and then mount a variety of attacks with the compromised nodes. To minimize the damage incurred by the compromised nodes, the system should detect and revoke them as soon as possible. To meet this need, researchers have recently proposed a variety of node compromise detection schemes in…

Handling Selfishness in Replica Allocation over a Mobile Ad Hoc Network

projects 2012 Handling Selfishness in Replica Allocation over a Mobile Ad Hoc Network– Mobile Computing, projects 2012 Abstract:Handling Selfishness in Replica Allocation over a Mobile Ad Hoc Network In a mobile ad hoc network, the mobility and resource constraints of mobile nodes may lead to network partitioning or performance degradation. Several data replication techniques have been proposed to minimize performance degradation. Most of them assume that all mobile nodes collaborate fully in terms of sharing their memory space. In reality, however, some nodes may selfishly decide only to cooperate partially,…

Toward Reliable Data Delivery for Highly Dynamic Mobile Ad Hoc Networks

projects 2012 Toward Reliable Data Delivery for Highly Dynamic Mobile Ad Hoc Networks- Mobile Computing, projects 2012 Abstract:Toward Reliable Data Delivery for Highly Dynamic Mobile Ad Hoc Networks This paper addresses the problem of delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. Most existing ad hoc routing protocols are susceptible to node mobility, especially for large-scale networks. Driven by this issue, we propose an efficient Position-based Opportunistic Routing (POR) protocol which takes advantage of the stateless property of geographic routing and the…

Fast Data Collection in Tree-Based Wireless Sensor Networks

projects 2012 Fast Data Collection in Tree-Based Wireless Sensor Networks– Mobile Computing, projects 2012 Abstract:Fast Data Collection in Tree-Based Wireless Sensor Networks We investigate the following fundamental question – how fast can information be collected from a wireless sensor network organized as tree? To address this, we explore and evaluate a number of different techniques using realistic simulation models under the many-to-one communication paradigm known as convergecast. We first consider time scheduling on a single frequency channel with the aim of minimizing the number of time slots required (schedule length)…
