Our primary interest is to design network protocols to efficiently build and maintain distributed communication systems based on opportunistic design principles. Such systems should continue to operate well even if communication is sporadic, no end-to-end routes are available, and sources and consumers of information are not known in advance. Also the environment poses many challenges, that are typical for wireless mobile devices, such as wireless channel impairments, the impossibility of having up-to-date and accurate views of the network topology at every device, and limited energy resources. In the second part of the paper, we discuss and propose solutions for data dissemination in such an environment by exploiting network coding techniques. Furthermore, we report first results which reveal that network coding largely outperforms standard solutions which are based on the classical store and forward paradigm.","PeriodicalId":262714,"journal":{"name":"International Conference in Integrated Internet Ad Hoc and Sensor Networks","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132568283","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}

Although this assumption simplified the path to adoption of WSN technology, researchers are now being attracted by more decentralized architectures with multiple sinks and heterogeneous nodes. These scenarios are brought to an extreme in Wireless Sensor and Actor Networks (WSANs), where sensing and acting nodes collaborate in a decentralized fashion to implement complex control loops. In these settings, new programming abstractions are required to manage complexity and heterogeneity without sacrificing efficiency.In this paper we propose and define a logical neighborhood programming abstraction. A logical neighborhood includes nearby nodes that satisfy predicates over their static (e.g., type) or dynamic (e.g., sensed values) characteristics. The span of the neighborhood and the definition of its predicates are specified declaratively, along with requirements about the cost of the communication involved. Logical neighborhoods enable the programmer to \"illuminate\" different areas of the network according to the application needs, effectively replacing the physical neighborhood provided by wireless broadcast with a higher-level, application-defined notion of proximity.This paper presents the definition of a declarative language for specifying logical neighborhoods, highlighting its expressiveness, flexibility and simplicity. Moreover, although the language constructs are readily implemented using existing communication mechanisms, we briefly report about a novel routing scheme we expressly designed to support efficiently our abstractions.","PeriodicalId":262714,"journal":{"name":"International Conference in Integrated Internet Ad Hoc and Sensor Networks","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121631811","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}

With the generally adopted single-sink architecture, be it static or mobile, such conditions arise due to contention near the sink as a result of multipath data delivery. The compactness of sensors with limited energy resources restricts the use of sophisticated FEC or ARQ mechanisms to improve the reliability of transmissions under such adverse conditions.We propose a novel virtual sink architecture for wireless sensor networks that mitigates the near-sink contention by defining a group of spatially diverse physical sinks. Reliability and energy efficiency is achieved through multipath data delivery to the sinks without the need for sophisticated FEC or ARQ mechanisms. This architecture is especially suitable for indoor environments, where channel conditions are harsh due to severe multipath fading, as well as emerging applications like underwater sensor networks where the predominant physical layer is acoustic communications, which is characterized by long propagation delays and severely fluctuating link conditions. We present our proposed architecture and demonstrate its efficacy using mathematical analysis.","PeriodicalId":262714,"journal":{"name":"International Conference in Integrated Internet Ad Hoc and Sensor Networks","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128228459","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 MANET, efficient support of multipoint communications is essential in order to provide services like group audio and video conferencing, dissemination of data to a set of receivers or collaboration of a group of users. However, most of these interactive services have very strong requirements regarding delay and bandwidth. Controlling the end-to-end delay and maintaining low packet loss rate is vital to support interactive multimedia applications in MANETs. In this paper, we present QAMNet, an approach to improve the Quality of Service (QoS) for multicast communication in MANETs. We extend existing mesh based multicast routing protocols by introducing traffic prioritization, distributed resource probing and admission control mechanisms and adaptive rate control of non-real-time traffic based on Medium Access Control (MAC) layer feedback to maintain low delay and required throughput for real-time multicast flows. Simulation results show that, by reusing control messages already used by those protocols, our approach does not significantly increase control overhead nor state stored at nodes compared while it manages to increase packet delivery ratio and reduce latency for real-time traffic.","PeriodicalId":262714,"journal":{"name":"International Conference in Integrated Internet Ad Hoc and Sensor Networks","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117105688","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}

This combination makes the implementation of software a demanding task and encourages to new approaches when thinking of software architecture.In this paper an architecture combining a low protocol stack with a cross-layer management entity is presented. One of the main ideas behind the architecture presented is to make application programming easier and to simplify the protocol stack in such a way that it would suit better for the limited resources available. The role of the cross-layer management entity is to offer a shared data structure and to take care of some sensor network specific functions, like topology management and power saving. It also provides certain services that applications and the layers in the protocol stack can use.This architecture has been created specially for needs of wireless sensor networks implementation and the special attention has been paid to modularity and testability of implementation. An implementation based on this cross-layer architecture, CiNet, is also presented in this paper. The functionality of the architecture and the CiNet network was verified by using two different protocol stacks. Wireless communication of the network is based on the 802.15.4 technology.","PeriodicalId":262714,"journal":{"name":"International Conference in Integrated Internet Ad Hoc and Sensor Networks","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131582154","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}
