In this paper, we propose TRACK - a novel sink mobility model exploiting the connected dominating set (CDS) property of a network graph. TRACK, to the best of our knowledge, is the first contemporary sink mobility model to exploit the CDS property for WSN lifetime longevity and secure data aggregation. In TRACK, the CDS of the given network is computed and then the minimum spanning tree (MST) of the CDS is constructed. Using the CDS-MST as the underlying framework, a Hamiltonian circuit (HC) is constructed, along which the sink is mobilized to traverse the network. Since TRACK, by the very definition of CDS, passes through the transmission range of every node in the network, data can be relayed directly from the source node to the sink, eliminating the need for multi-hop routing. By virtue of this property, nodes in the WSN are discharged from their routing obligations and data aggregation becomes more secure. Additionally, we propose an extended version of TRACK called M-TRACK in this paper. The extended model trades higher fractions of sensor energy with the objective of minimizing the length of sink trajectory. This consequently minimizes the delay between consecutive sink visits, mitigating buffer-overflow of sensors. M-TRACK does necessitate multi-hop routing, but keeps it within a bounded number of hops. We confirm the efficiency and robustness of our models via simulation and analysis, and show that our model can extend the WSN lifetime up to seven times that which can be achieved using a static sink.","PeriodicalId":314071,"journal":{"name":"2008 Proceedings of 17th International Conference on Computer Communications and Networks","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130609178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current IEEE 802.11 standards, whenever a wireless station wants to leave the network, it sends a deauthentication or disassociation frame to the access point. These two frames, however, are sent unencrypted and are not authenticated by the access point. Therefore, an attacker can launch a DoS attack by spoofing these messages and thus disabling the communication between a wireless device and its access point. We propose an efficient solution based on a one way hard function to verify that a deauthentication/disassociation frame is from a legitimate station. We implement our solution on some 802.11 devices and the experimental results show that our protocol is highly effective against this DoS attack.","PeriodicalId":314071,"journal":{"name":"2008 Proceedings of 17th International Conference on Computer Communications and Networks","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132634098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to develop a network architecture which is able to guaranty quality of service requirements for high priority traffic. In Wireless Multimedia Sensor Networks (WMSNs), a sensor node may have different kinds of sensor which gather different types of data, with differing levels of importance. We argue that the sensor networks should be willing to spend more resources in disseminating packets that carry more important information. Some applications of WMSNs need to send real time traffic toward the sink node. This real time traffic requires low latency and high reliability so that immediate remedial and defensive actions can be taken, where necessary. Similar to wired networks, service differentiation in wireless sensor networks is also very important. In this paper we propose a differentiated service model for WMSNs. The proposed model can provide requested quality of service for high priority real time classes. In the proposed model, we distinguish high priority real time traffic from the low priority non-real time traffic, and input traffic streams are then serviced based on their priorities. Simulation results confirm the efficiency of the proposed model.","PeriodicalId":314071,"journal":{"name":"2008 Proceedings of 17th International Conference on Computer Communications and Networks","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126188118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main pillars of our architecture are communication pivots called information dispatch points (IDPs) which embed the concept of modularity at all levels of the architecture. IDPs completely decouple functional entities by means of indirection thus enabling evolving protocol stacks. Our architecture also provides a consistent application programming interface (API) to access node-local or network-wide functionality.

The low computational complexity reduces the detection time and improves the radio agility. In this paper, we present a framework to analyze the performance of this covariance-based method.

At a time of such challenges, this paper arises from the need to identify robust technical telemonitoring solutions that are both open and interoperable in home or mobile scenarios. These middleware systems demand standardized solutions to be cost effective and to take advantage of standardized operation and interoperability. Thus, a fundamental challenge is to design a plug-&-play platform that, either as individual elements or as components, can be incorporated in a simple way into different telecare systems, perhaps configuring a personal user network. Moreover, there is an increasing market pressure from companies not traditionally involved in medical markets, asking for a standard for personal health devices (PHD), which foresee a vast demand for telemonitoring, wellness, ambient assisted living (AAL) and applications for ubiquitous-health (u-health). However, the newly emerging situations imply very strict requirements for the protocols involved in the communication. The ISO/IEEE 11073 (X73) family of standards is adapting to new personal devices, implementing high quality sensors, and supporting wireless transport (e.g. Bluetooth) and the access to faster and reliable communication network resources. Its optimized version (X73-PHD) is adequate for this new technology snapshot and might appear the best-positioned international standards to reach this goal. This work presents an updated survey of this standard and its implementation in a middleware telemonitoring platform.","PeriodicalId":314071,"journal":{"name":"2008 Proceedings of 17th International Conference on Computer Communications and Networks","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128657379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
