This report demonstrates lateral inhibition and some of its important properties. For electronic sensors, the method uses radio signal strength as an indication of distance, but is robust to reflection interference because it uses pooling of multiple sensor output. The contribution of this work is a new tool for sensor localization, useful alone or in combination with other methods. A Java¿ application provides the figures shown here, and is available for demonstrating lateral inhibition for different signal strength, sensor layout, and reflectivity values. Computational algorithms are available on request.","PeriodicalId":299596,"journal":{"name":"2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132554281","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}

Since reliability and security compete for the same resources, we jointly solve for error control coding and integrity for a broadcast scenario. Hence, it is very important that data packets are received by all nodes in the network using minimum number of transmissions and with a minimum latency because of the limited resources of the sensor nodes and the urgency of the information. We assume that the adversary can drop (or modify) legitimate packets and inject its own packets by compromising nodes. Thus, it is critical that, any node receiving a malicious packet immediately filters it out and uses only the legitimate ones for forwarding to the next hop and decoding. This makes the packet authentication a very challenging problem for broadcast. We build our authentication scheme, on top of a reliable and energy-efficient broadcasting protocol called Collaborative Rateless Broadcast (CRBcast) to achieve efficiency, reliability and authenticity.","PeriodicalId":299596,"journal":{"name":"2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126435806","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}

Fundamental to these efforts is a reliable communications infrastructure that allows the disaster response teams to coordinate and exchange information in an efficient manner. Existing solutions for disaster response are inadequate as they suffer from interoperability problems and lack the appropriate amount of flexibility. In this paper, we propose SAFIRE, a novel multi-hop architecture for facilitating fast and reliable information exchange between first responders. The salient features of SAFIRE are (1) A decentralized cognitive radio-based approach for supporting direct communication between first responders, (2) A publish-subscribe mechanism for exchanging information among first responders, and (3) A flexible multi-layered policy framework for optimally configuring the system. We present the challenges in designing SAFIRE, and outline its basic components. We believe our exploration of such an architecture opens up a set of unique challenges related to the integration of different systems to realize SAFIRE, giving rise to new avenues for research In communication systems for disaster response.","PeriodicalId":299596,"journal":{"name":"2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132326962","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}

To evaluate the solution to a problemn in this area, it is often infeasible to have a practical deployment of a sensor network. In such cases, simulations in the form of computer software programs are employed. SenNetSim is a novel Graphical User Interface (GUI) based simulator which provides a framework to model a sensor network for coverage applications. SenNetSim is composed of four components - the main application window, the control panel, the sensor library, and the graph window. The main application window, shown in Figure 1, allows the user to add and remove sensor nodes and define the region to be covered. As the Application is document-based, there may be several main windows open at the same time. However, the user can work only on one window at a time, the current working window is referred to as the current document. The control panel, shown in Figure 2 is a floating palette which displays the attributes corresponding to the objects in the current document. It has four sections that provide information on the current document, selected node(s), grid settings, and covers. A toggle button allows the user to close a particular section when it is not required.","PeriodicalId":299596,"journal":{"name":"2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125606554","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 a dynamically changing spectrum environment, it is very important to design a distributed access scheme that can coordinate different users' access adapt to spectrum dynamics with only local information. In this paper, we propose a self-learning repeated game framework for distributed primary-prioritized dynamic spectrum access through modeling the interactions between secondary users as a noncooperative game. With the proposed framework, the inefficiency due to users' selfish behavior can be highly improved, and the secondary users can distributively obtain their optimal access probabilities with only local observations. The simulation results show that the proposed framework can achieve comparable performances with those of the centralized primary-prioritized dynamic spectrum aess sheme.","PeriodicalId":299596,"journal":{"name":"2007 2nd IEEE Workshop on Networking Technologies for Software Define Radio Networks","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122806717","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}
