We consider a transmission protocol for a multihop wireless network that does not restrict its transmission range within one hop. In the crosslayer design approach, we adopt diversity gain in the physical layer, automatic request for retransmission (ARQ) in the data-link layer and optimal number of hops in the network layer. We focus on the optimal transmission-rate and minimum number of hops of a linear multihop network. An optimal automatic request for cooperation (ARC) based multihop protocol is proposed to maximize the end-to-end throughput and minimize the number of retransmission. In this optimal protocol, all succeeding relays of a transmitting terminal require to receive the packet and send feedback. Although it gives the optimal performance, the implementation complexity of such protocol is very high. To achieve a good complexity-performance tradeoff, a K-hop ARC based multihop protocol is further proposed, where only the K succeeding relay nodes receive the transmitted packet and send feedback. Simulation results are provided to show that the proposed protocols outperform the conventional multihop protocol and the multihop diversity protocol in terms of end-to-end throughput.","PeriodicalId":402292,"journal":{"name":"2010 16th Asia-Pacific Conference on Communications (APCC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117308474","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 infrastructure mode of IEEE 802.11, wireless terminals, or stations (STAs), share one access point (AP). Since TCP congestion control increases the congestion window size until packet loss occurs, TCP communication takes excessive bandwidth from other communications. Then, TCP communication affect the communication quality of the other STAs which share the same AP. Especially, the communication quality for real-time applications such as video streaming becomes worse. In order to solve this problem, our method estimates the channel occupancy of the wireless LAN and adjusts TCP window size so as not to affect the other communications. When an STA simultaneously makes a real-time UDP communication and a background TCP communication, the proposed method controls the window size without taking bandwidth from the UDP communication. We have evaluated the proposed method by computer simulation experiments and show that the proposed method makes it possible to improve the communication quality of the real-time UDP communication.","PeriodicalId":402292,"journal":{"name":"2010 16th Asia-Pacific Conference on Communications (APCC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127866714","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 sensor nodes are very much constrained in power supply, extending lifetime of these sensors is essential. On the other hand, it is difficult to provide reliable data transfer in WSNs because of their unreliable link quality and congestion at a cluster head (CH) node. CHs perform the crucial inter-cluster communication task for WSN. However, extreme use of energy due to relaying multi-hop data traffic leads to sudden death of a CH node. Existing routing protocols usually utilize minimum hop count or energy consumption path for inter-cluster path selection; consequently, they ignore the reliability in the routing process. In this paper, we have proposed an optimal inter-cluster routing technique considering both energy consumption and reliability. Reliability is measured in terms of link quality and congestion that mainly introduce data loss. Simulation results demonstrate that the proposed technique has improved both network lifetime and reliability significantly compared with the contemporary cluster based routing techniques.","PeriodicalId":402292,"journal":{"name":"2010 16th Asia-Pacific Conference on Communications (APCC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125109085","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}
