Mobility of a Base Station for Simultaneous Multiple Events in a Static Wireless Sensor Network

Mobility of a Base Station for Simultaneous Multiple Events ...

IEEE National Conference on Aerospace and Electronics (NAECON)

作者： Smita Toshniwal Amit Gaur Demin Wang Dharma P. Agrawal OBR Research Center for Distributed and Mobile Computing CS Department University of Cincinnati Cincinnati OH USA

Energy constrained nature and unattended deployment of sensors motivates the need of special techniques for designing reliable wireless sensor networks. Recently many approaches are considering mobile sensor nodes to deal with this problem. But making all the sensors mobile involves more signaling overhead for network maintenance. It is energy efficient to move the base station which has no power limitations. Also, there are many real life applications in which event based approach is more appropriate. In this paper, we propose an adaptive scheme for a mobile base station that moves according to the occurrence of events. We propose two optimization schemes: moving the BS towards the event centroid and moving the BS towards distance based weighted centroid. Simulation results show that moving the base station adaptively significantly prolongs the network lifetime.

作者： Biswas, Ratnabali Chowdhury, Kaushik Agrawal, Dharma P. OBR Research Center for Distributed and Mobile Computing Department of ECECS University of Cincinnati Cincinnati OH 45221-0030 United States

Wireless sensor network is an emerging technology that enables remote monitoring of large geographical regions. In this paper, we address the problem of distributing attributes over such a large-scale sensor network so that the cost of data retrieval is minimized. The proposed scheme is a data-centric storage scheme where the attributes are distributed over the network depending on the correlations between them. The problem addressed here is similar to the Allocation Problem of distributed databases. In this paper, we have defined the Allocation Problem in the context of sensor networks and have proposed a scheme for finding a good distribution of attributes to the sensor network. We also propose an architecture for query processing given such a distribution of attributes. We analytically determine the conditions under which the proposed architecture is beneficial and present simulation results to demonstrate the same. To the best of our knowledge, this is the first attempt to determine an allocation of attributes over a sensor network based on the correlations between attributes. © Springer Science+Business Media, LLC 2006.

Multiple beam antennas can receive (or transmit) data on multiple beams simultaneously. The aim of this paper is to show the limitations of using IEEE 802.11 distributed coordination function (DCF) based schemes for medium access control (MAC) in such antennas. We provide four different variants of IEEE 802.11 DCF based on-demand protocols to study this phenomenon. Our simulation results and analyses emphasize the need to develop a novel MAC protocol to fully exploit the capabilities of multiple beam antennas. We further provide some embryonic guidelines for the development of such a protocol. © 2005 IEEE.

ISBN: (纸本)0780389662

Wireless sensor networks is an emerging technology that can significantly improve the quality of spatio-temporal data monitoring because of their untethered operation and potential for large scale deployment. In this paper, we define a communication architecture that supports distributed query processing to evaluate spatio-temporal queries within the network. We represent these queries by query trees and distribute query operators to appropriate sensor nodes. As operator execution demands high computation capability, we propose use of a heterogenous sensor network where query operators are assigned to sparsely deployed resource-rich nodes within a dense network of low power sensor nodes. We design an adaptive, decentralized, low communication overhead algorithm to determine an operator placement on the resource-rich nodes in the network to minimize cost of transmitting data along a routing tree constructed to continuously retrieve data at the sink, from a set of spatially distributed geographical regions. To the best of our knowledge, this is the first attempt to build an energy aware routing infrastructure to enable in-network processing of spatio-temporal queries. © 2005 IEEE.

ISBN: (纸本)0780394143

This paper introduces a novel cross layer medium access control protocol for multiple beam antennas to fully utilize their multiple-beam-forming capability. Our protocol, Explicit Synchronization via Intelligent Feedback (ESIF), uses feedback from neighboring nodes to synchronize data communication at multiple beams. ESIF exploits routing information to guarantee long-term fairness and minimize the energy and latency overheads. Unlike previous works on directional antennas that discuss range extension, we focus on optimal spatial reuse. Simulation results demonstrate that ESIF outperforms other ondemand access schemes based on IEEE 802.11 DCF for multiple beam antennas.

Future wireless networks are expected to integrate heterogeneous devices equipped with multiple radios and different characteristics. Therefore, it is important to understand how these heterogeneous radios can affect connectivity and overall multi-hop network performance. In this paper, we study the connectivity of a heterogeneous ad hoc network. We consider two types of nodes: nodes equipped with a single communication interface with communication range r, and Dual-Mode (DM) nodes, equipped with two communication interfaces with two different communication ranges r and rf, respectively, where r f>r. We assume the radios in the DM nodes operate in two different channels. We provide a theoretical analysis of connectivity in a linear network and we present simulation results for the two-dimensional case that show the impact of DM nodes on connectivity, broadcast latency and robustness in static scenarios. © 2005 IEEE.

In this paper we propose a Directional Routing Protocol (DRP) for MANETs. DRP is an on-demand directional routing protocol which assumes a cross layer interaction between routing and MAC layer. The main features of DRP include an efficient route discovery mechanism, establishment and maintenance of directional routing and directional neighbor tables (DRT and DNT respectively), and novel directional route recovery mechanisms. We have implemented DRP on top of an existing MAC protocol for directional antennas and have compared its performance with the popular dynamic source routing (DSR) protocol over both omni-directional and directional antenna models. Preliminary simulation results are found to be very promising. © 2005 IEEE.

Historically, a large number of small and cheaper sensors are deployed to form a sensor network. This paper provides rationale behind using an Aggregate Logical Sensor Unit (ALSU) as a building block in a Wireless Sensory Information network (WSIN). In this architecture, a single ALSU is composed of many off-the-shelf sensor nodes in the manner similar to the Beowulf cluster concept. The highly capable, cost effective and flexible ALSUs built in this manner from several smaller physical sensor nodes, would enable high computation power and built-in reliability for sensor applications. The objective of this paper is to provide an alternative where energy and computation is not a limiting factor in order to achieve the operational objectives of WSIN applications. This paper highlights critical issues that need to be addressed in developing a framework where each ALSU could have the capability to perform required operations as dictated by an underlying application. © 2005 IEEE.
