sensor localization in wireless sensor networks is an important component of many applications. Previous work has demonstrated how localization can be achieved using various methods. In this paper we focus on achieving finegrained localization that does not require external infrastructure, specialized hardware support, or excessive sensor resources. We use a real sensor network and provide measurements on the actual system. We adopt a localization approach that relies on acoustic sounds and clock synchronization. the contribution of our work is achieving consistent sound pulse detection at each sensor and precise range estimation using a high-precision clock synchronization implementation. We first describe our technique and then we evaluate our approach using a real setup. Our results show that our approach achieves an average clock synchronization accuracy of 5μs. We verify this accuracy using an external global clock via an interrupt mechanism. Our sound detection technique is able to consistently identify sound pulses up to 10m distances in indoor environments. Combining the two techniques, we find that our localization method results in accurate range estimation with an average error of 11cm in distances up to 7m and in consistent range estimation up to 10m in various indoor environments.

作者： Kiran K. Rachuri C. Siva Ram Murthy Indian Institute of Technology Madras Chennai India

Random walk is one of the widely used techniques for information discovery in unstructured networks like ad hoc wireless networks (AWNs) and wireless sensor networks (WSNs). In a random walk, instead of taking all steps uniform randomly, our idea is to modify random walk to take some level biased steps to improve its energy efficiency and latency which are important design parameters in WSNs. the level of a node is defined as the minimum number of hops required for a packet to reach the sink node from that node. We propose two walk based search protocols viz., several short random walks (SSRW) search and random walk with level biased jumps (RWLBJ) search, that use a combination of uniform random and level biased steps for energy efficient search in WSNs. the idea is that the biased steps in the proposed protocols decrease the correlation among visited sensor nodes which increases the node coverage of the protocols. We show by theoretical analysis that using biased steps in random walks increases their efficiency in terms of energy consumption and latency of search. We also show by extensive simulations that SSRW and RWLBJ are better choices compared to that of pure random walk in terms of the energy consumption and latency of search.

Aid supporting systems for emergency cases to collect patientspsila medical data such as their conditions, blood pressure and so on real-time are developing recently. Part of them form sensor network and collect patientspsila medical data. Among data,there are important data needed to be sent immediately. However, sending the data with unicast has problem about loss at midstream of the path. On the other hand,flooding the data makes amount of traffic too huge which oversaturates the bandwidth. For sending the data certainly, it is required to keep traffic low and path diversity large. In this paper, we propose emergent messages ending method, EMPaD, enlarging path diversity and keeping the amount of traffic low. Using simulations, we evaluate the proposal, and results show that our proposal enlarges path diversity while traffic is kept low.

作者： Saeed Rashwand Jelena Misic Vojislav Misic Subir Biswas Md Mahbubul Haque Department of Computer Science University of Manitoba Winnipeg Canada

Wireless sensor networks use battery-operated computing and sensing devices. It is often impractical or even impossible to charge/replace the exhausted batteries of the nodes. thus, energy consumption is the main concern in a wireless sensor network. Moreover, a critical event detected by the sensor network should be delivered to the user as soon as possible. thus, for sensor networks, both energy efficiency and transmission latency are important parameters. In this paper, we propose a novel asynchronous, duty cycled, energy efficient, and low transmission delay for wireless sensor networks, which addresses all the sources of energy waste to make the medium access more energy efficient, while keeping transmission delay *** currently available asynchronous contention-based MAC protocols require that proper strategies for sender and receiver nodes are provided to rendezvous. However, the proposed protocol does not rely on any rendezvous between sender and receiver. For evaluating the novel MAC protocol, we have simulated this protocol and two very efficient and established MAC protocols, RTS/CTS ieee 802.11 and S-MAC. the simulation results indicate that the proposed protocol has very good performance. In addition, as the results show, the novel protocol provides a very suitable balance between energy efficiency and transmission delay.

For wireless sensor networks, how to efficiently utilize limited energy directly affects the lifetime and the cost. LEACH is a clustering-based protocol with good performance, which employs localized coordination to balance the energy usage. In this paper, an improved LEACH protocol is proposed with a more reasonable set-up phase. the proposed protocol focuses on saving the energy cost induced due to redundant nodes and balancing the energy consumption among sensor nodes by splitting large clusters into smaller ones. Simulation results, compared with LEACH, demonstrate that the proposed protocol can reduce energy consumption and hence prolong the lifetime of WSN.

Localization is a crucial service for various applications in wireless sensor networks (WSNs). Although most researches assume stationary nodes, sensor mobility can enrich the application scenarios. Existing dynamic localization approaches require high seed density or incur a large communication overhead. In order to address these problems, we propose an efficient rang-free localization algorithm, EUL, which utilizes the relationship between neighboring nodes to estimate their possible location boundaries. Our algorithm not only allows all the nodes to remain static or move freely but also reduces the dependence on seeds, which achieves a uniform energy distribution to address the excessive energy drain around seeds and lengthen the network lifetime. We have evaluated EUL together with other major dynamic localization approaches. Simulation results show that EUL outperforms existing approaches in terms of accuracy under many different mobility conditions.

international conference on distributed computing systems Workshop

作者： Torsten Braun University of Bern Switzerland

Wireless mesh networks can be used for various applications such as extending the coverage of wireless networks or connecting remote users to the Internet. By using wireless mesh networks for interconnecting meteorological weather stations to the Internet, multi-media sensor data can be observed in real-time. In such an application scenario, the wireless multi-hop network must fulfill high application requirements in terms of reliability, delay, and bandwidth. the exploitation of diversity mechanisms based on multiple paths seems to be a promising approach. the talk will present implementation experiences with wireless multi-path transmission and deployments of wireless mesh networks in out-door scenarios to interconnect remote weather stations with the Internet. Moreover, an evaluation and test environment for wireless mesh network implementations based on emulation and simulation to model realistic wireless channel conditions will be presented. the talk concludes with a discussion on how cognitive networking concepts can help to achieve the application requirements mentioned above.

作者： Yanyan Zhuang Jianping Pan Guoxing Wu Department of Computer Science University of Victoria Victoria BC Canada School of Computer Science South-East University Nanjing Jiangsu China

Wireless microsensor networks usually consist of a large number of small sensor nodes with limited onboard energy supply and deployed densely in a given area for information harvesting purposes. To reduce energy consumption and prolong network lifetime, clustering techniques are often used, among which the grid-based ones are very popular due to their simplicity and scalability. In this paper, we analyze and evaluate the energy-optimal grid size for a grid-based clustering and routing scheme proposed specifically for wireless microsensor networks. through numerical and simulation results, we reveal the tradeoff generic to all grid-based clustering schemes. In addition, we propose a randomized technique to further prolong the network lifetime and discuss other energy-saving opportunities. this paper provides some insights into the intrinsic limits of grid-based clustering schemes for wireless micro sensor networks.

Clustering is one of the most popular approaches used in wireless sensor networks to conserve energy and increase node as well as network lifetime. In this paper we have analyzed the affect of confinement of event field within the sensor field on network lifetime and network energy consumption for cluster-based wireless sensor networks based upon LEACH protocol which is among the most popular clustering protocols proposed for these types of networks. Simulation results based upon this protocol identify some important factors that induce unbalanced energy consumption among sensor nodes which are located inside the event field to those which are located outside the event field and hence affect the network lifetime. this highlights the need for an adaptive clustering protocol that can increase the network lifetime by further balancing the energy consumption among sensor nodes. Paper concludes with some recommendations for such protocol.
