In this paper, we propose a new multi-interface equipped architecture, named \"wireless bonding (WBond)\", which enables each node to fully utilize all its available interfaces, resulting in increased throughput. The proposed WBond provides a method for exposing a single virtual interface by bonding multiple NICs. When a node needs to transfer a packet, WBond selects one among the multiple interfaces depending upon the channel quality assigned to each interface. A novel method for measuring channel quality, called as \"ChanQual\", is presented and used by the WBond with high accuracy and no additional overhead. Comparison studies using ns-2 simulations show that our WBond scheme can achieve the most reliable and highest performance (i.e., network throughput) compared to traditional multi-interface architectures","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127420233","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}

A dual-control planes model is presented, which includes the traditional S(stationary)-plane for message routing among stationary nodes using connection-based message routing. In addition, we introduce a new control plane, M(mobile)-plane, for trajectory control of mobile nodes. A message routing consists of a sequence of control plane switches, alternating between store-and-forward in the S-plane and store-carry-forward in the M-plane. Intra-plane and inter-plane communication is performed through contacts. In the M-plane, unlike most existing works that focus on two extremes of spectrums (random movement and tightly controlled movement), our approach focuses on loosely-controlled movement of mobile nodes to assist message routing in a store-carry-forward paradigm. The challenge lies in adapting the degree of control to support a certain degree of flexibility, such as using dynamic node trajectory to maximize route sharing to minimize the number of carriers, while ensuring some desirable global properties, such as short average-moving-distance and a small number of relays to increase network capacity","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129895301","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}

A number of conditions differ from the speech signal over IP network with heterogeneous devices while voice traffic is transported by packet-based in ubiquitous environment. In this paper, voice signals in packet loss and noise is controlled for the guaranteed quality of service (QoS) on the IP network which are responsible for digitizing, encoding, decoding, and playing out the speech signal. We implement the algorithms of packet loss concealment (PLC) and noise reduction, which is called PEA (pervasive environment adaptation)-PLC, PEA-noise reduction together, for providing high quality voice-based pervasive computing services. The proposed PEA-PLC algorithms are applied as post-processing after decoding on devices, and then PEA-noise reduction method is applied as pre-processing before speech coding. The proposed PEA-algorithms for packet loss and noise are applied in G.729A codec optimally using mobile-softphone and a 1-port gateway PSTN phone system. The performances of the proposed methods are evaluated by the PESQ measurement in various packet loss and noisy conditions","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132414829","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}

Over the past few years, impressive advances in wireless networking and embedded computing have led to the \"first generation\" of wireless sensor networks. In general, these are used for monitoring or tracking applications characterized by low data rates and static deployments. In this talk, I will motivate what the \"second generation\" might look like, focusing on mobile sensor networks gathering heterogeneous \"media-rich\" data. These networks offer the opportunity to sense the world at much higher scale and finer fidelity than their static counterparts, especially over large areas. With hundreds of millions of automobiles and over a billion cell phone-equipped people in the world, cars and humans may turn out to be the vehicles of the world's largest and most dynamic sensor networks in the coming years. This talk will discuss several network architecture challenges in realizing this vision. Meeting these challenges will give us a network architecture that can support a wide range of vehicular network applications, far beyond the area of mobile sensor networks","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131557931","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}
