An active tape is a sequence of sensor nodes and related units (such as batteries) organized around a bus. A bus of programmable sensor nodes is, in effect, a programmable linear array, thus the term active tape. A bus provides a simple mechanism to share resources. In a sensor network context, the primary sharing concerns center around energy, sensing and networking. This paper serves as an introduction and initial exploration into the design space of active tapes.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121535614","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}

We propose a model of link redundancy for wireless networks. Using this model, we show that once a sufficiently high node density has enabled complete connectivity with respect to a single linking technology in an uncluttered environment, cross-network connectivity with randomly located obstructions present might be more efficiently achieved by utilizing multiple internode links than by increasing node density.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"50 S5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113964090","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 phenomenon causes packets of a multi-hop flow to interfere with each other as they are relayed over the multi-hop route. This interference, an instance of the notorious hidden terminal problem, is caused by simultaneous transmissions by down-stream nodes unaware of ongoing transmissions by up-stream nodes. DMAC (deferrable MAC) is a novel MAC protocol that alleviates the hidden terminal problem by deferring further transmissions until the previously transmitted packets travel far enough to avoid interference with the newly transmitted packets. For simple chain topologies, DMAC improves the throughput of CBR and TCP flows by up to 100% and 60%, respectively. For random mobile topologies with up to 40 simultaneous flows, DMAC improves the throughput of TCP flows by up to 30%.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132103853","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}

Re-routing instability in IEEE 802.11 multi-hop ad-hoc networks IEEE 802.11多跳自组织网络中的重路由不稳定性

Liew","doi":"10.1109/LCN.2004.102","DOIUrl":"https://doi.org/10.1109/LCN.2004.102","url":null,"abstract":"TCP throughput instability is a well-known phenomenon in IEEE 802.11 multi-hop ad-hoc networks. However, we find that this problem is not restricted to TCP traffic only, but also occurs in UDP traffic. The associated throughput oscillations are not acceptable for real-time applications such as video conferencing and voice-over-IP. The paper re-defines this throughput fluctuation as a \"re-routing instability problem\" since it is caused by the triggering of the re-routing function. In particular, we show that the throughput instability is mainly induced by re-routing, not the binary exponential back-off of the IEEE 802.11 MAC protocol. Turning off the re-routing function, for example, eliminates the problem. We believe that this is the first paper to study this phenomenon in the context of re-routing instability. We propose to modify the ad-hoc routing protocols with a \"don't-break-before-you-can-make\" strategy. The scheme does not require modifications of the IEEE 802.11 standard, making it readily deployable using existing commercial wireless LAN (WLAN) products. Simulations show that the proposed scheme can significantly reduce the throughput variation in a traffic flow by 50-70% and improve the average throughput by up to 11%.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123817848","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 causes differences in transmission rate among mobile stations due to the use of link adaptation schemes. We analyse fairness in the presence of these impairments for the distributed contention based access mechanisms of the IEEE 802.11 and 802.11e standards. The notion of fairness is explored in terms of utility derived from the network (i.e. throughput) and allocated resources (i.e. amount of time permitted to transmit). We show how fairness can be achieved by judicious choice of parameters and study the impact of these choices on capacity. Finally, we demonstrate how these findings could affect other related designs including admission control and charging schemes.","PeriodicalId":366183,"journal":{"name":"29th Annual IEEE International Conference on Local Computer Networks","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116922476","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}

Contiki is built around an event-driven kernel but provides optional preemptive multithreading that can be applied to individual processes.
