Minimizing Delay And Maximizing Lifetime For Wireless Sensor Networks With Any Cast

IEEE 2010 In this paper, we are interested in minimizing the delay and maximizing the lifetime of event-driven wireless sensor networks for which events occur infrequently. In such systems, most of the energy is consumed when the radios are on, waiting for a packet to arrive. Sleep-wake scheduling is an effective mechanism to prolong the [...]

A Fault Tolerant Communication Architecture Supporting Critical Monitoring With Wireless Sensor Networks

IEEE 2010 This paper deals with an integrated MAC and Routing protocol, able to manage faults occurring in Wireless Sensor Network (WSN). To this end, the protocol design has been inspired by the cross-layer principle to minimize both the signaling overhead and power consumption. After an accurate functional characterization, the performance is presented for the [...]

A Cooperative Diversity-Based Robust Mac Protocol In Wireless Ad Hoc Networks

IEEE 2011 In interference-rich and noisy environment, wireless communication is often hampered by unreliable communication links. Recently, there has been active research on cooperative communication that improves the communication reliability by having a collection of radio terminals transmit signals in a cooperative way. This paper proposes a medium access control (MAC) algorithm, called Cooperative Diversity [...]

Mitigating Selective Forwarding Attacks With A Channel-Aware Approach In WMNS

IEEE 2010 In this paper, we consider a special case of denial of service (DoS) attack in wireless mesh networks (WMNs) known as selective forwarding attack (a.k.a gray hole attacks). With such an attack, a misbehaving mesh router just forwards a subset of the packets it receives but drops the others. While most of the [...]

Optimize Storage Placement In Sensor Networks

IEEE 2010 Data storage has become an important issue in sensor networks as a large amount of collected data need to be archived for future information retrieval. Storage nodes are introduced in this paper to store the data collected from the sensors in their proximities. The storage nodes alleviate the heavy load of transmitting all [...]

Secure Data Collection In Wireless Sensor Networks Using Randomized Dispersive Routes

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 adversary acquires the routing [...]

SSUM: Smart Server Update Mechanism For Maintaining Cache Consistency In Mobile Environments- Mobile Computing

IEEE 2010 This paper proposes a cache consistency scheme based on a previously proposed architecture for caching database data in MANETs. The original scheme for data caching stores the queries that are submitted by requesting nodes in special nodes, called query directories (QDs), and uses these queries to locate the data (responses) that are stored [...]

Binrank: Scaling Dynamic Authority-Based Search Using Materialized Subgraphs – August 2010 – Knowledge And Data Engineering / Data Mining – J2EE Dynamic authority-based keyword search algorithms, such as ObjectRank and personalized PageRank, leverage semantic link information to provide high quality, high recall search in databases, and the Web. Conceptually, these algorithms require a querytime PageRank-style [...]
