It is not likely that we will see in the near future a unified MAC protocol for wireless sensor networks that is suitable for all wireless sensor applications. In this context, we propose an event based medium access control (EB-MAC) that is tailored for event based systems. Typically, event based systems are characterized by having long periods of inactivity and short abrupt periods of high data contention when an event is detected. High data traffic is generated simultaneously from all sensors detecting the event to deliver captured data. EB-MAC arranges data transfer dynamically using an election based scheduling technique. When data transfer begins, each sensor at a time starts sending data packets in a contention free environment. The protocol is implemented on MicaZ sensor motes where it showed efficiency in reliability, throughput and energy conservation. The algorithm is compared with an implementation of B-MAC with RTS/CTS on MicaZ where it showed its superiority in throughput and latency.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121910689","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}

Voids in networks often cause existing geographic routing algorithms to fail. In this paper, we propose a novel geographic routing algorithm called “Greedy Forwarding with VIrtual Position (ViP)”. We introduce virtual position as the middle position of all direct neighbors of a node. Instead of comparing nodes' real geographic positions, ViP employs virtual positions when selecting the next hop. Such virtual position reflects the neighborhood of a sensor node, as well as the tendency of further forwarding. For sparsely-deployed networks, ViP increases success rate of packet routing without introducing significant overhead. Furthermore, multiple levels of virtual position can be obtained with localized iteration. We propose the “Greedy Forwarding with Multi-level Virtual Position (MVP)” algorithm and the “Greedy Forwarding with Hierarchical Virtual Position (HVP)” algorithm. Different levels of virtual positions and their combinations are used alternatively to increase success rate of packet routing in sensor networks.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121984645","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 work defines an instance of a presence-based messaging system called Pebbles and Urns. A survey of current messaging systems has indicated key missing elements that are addressed by functionality in the Pebbles and Urns architecture. Current context-based messaging research focuses on the social activities and social interactions of the user. While that is important, this work proposes how Pebbles and Urns would augment the numerous ways a person deploys, obtains, and realizes information in their daily activities. Next, it considers agent design and tuplespaces as implementation components of Pebbles and Urns. An agent's ability to react to context, combined with tuplespace characteristics of distributed, associative memory, persistent storage, and destination - space - time uncoupling allow the investigation of new messaging schemes offering interesting advantages over existing messaging systems. This work closes with several Pebbles and Urns user scenarios and suggested future work to extend the Pebbles and Urns messaging system.","PeriodicalId":322416,"journal":{"name":"2009 IEEE International Conference on Pervasive Computing and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130143814","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}
