Computing capability comes in various forms and is embedded in different physical objects, ranging from miniature devices such as human implants and tiny sensor particles, to large constructions such as vehicles and entire buildings. The number of possible interactions among such elements, some of which may be invisible or offer similar functionality, is growing fast so that it becomes increasingly hard to combine or select between them. Mechanisms are thus required for intelligent matchmaking that will achieve controlled system behavior, yet without requiring the user to continuously input desirable options in an explicit manner. In this paper we argue that information about the co-location relationship of computing elements is quite valuable in this respect and can be exploited to guide automated service selection with minimal or no user involvement. We also discuss the implementation of such mechanism that is part of our runtime system for smart objects.","PeriodicalId":129488,"journal":{"name":"The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133758603","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}

It enables wireless devices to operate at high data rate when the channel condition is sufficiently good. Existing ad hoc routing protocols can not perform very well in the multi-rate ad hoc networks because they generally assume that bandwidth of different links are identical in the system. One straightforward solution to this issue is to use special routing metrics in routing algorithm, which is called routing approach. However, we believe that only localized reaction is performed in response to the local event. Based on this design principle, we propose a relay based medium access scheme to employ multi-rate capability even if existing minimum-hop based routing protocols are used. This scheme takes advantage of the node residing between neighboring nodes as a relay node and transforms a long-range transmission into two short-range transmissions. In our scheme design, we are very careful in reducing the additional overhead caused in order to exploit the high data rate transmission. Simulations show that our scheme achieve better throughput compared with 802.11 MAC scheme, a rate-adaptive MAC protocol called RBAR and the routing approach.","PeriodicalId":129488,"journal":{"name":"The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126769576","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}

Nevertheless, such networks can be built on top of any medium access scheme. An example are Bluetooth multi-hop networks (so called scatternets). In practice, many devices support several interfaces although the protocol stack used in each interface tends to be interface specific at the lower layers. This limits the ability of a device to switch back and forth between networks as need and opportunity dictates. As a step towards providing a more flexible handover infrastructure, in this paper we address the issue of integrating heterogeneous, mobile ad-hoc networks that use different MAC layer protocols. The goal is to provide an end-to-end communication abstraction that hides heterogeneity. In the paper, we discuss different possible designs with regard to application transparency, performance and mobility. Using these ideas, we describe an IP based heterogeneous mobile ad hoc testbed using Bluetooth and IEEE 802.11 that implements a virtual interface approach as the end-to-end abstraction. Furthermore, we also provide a detailed evaluation of the system in terms of throughput and handover-time.","PeriodicalId":129488,"journal":{"name":"The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126084303","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}

An infrastructure supported approach is required to provide non-disrupted services with seamless roaming capabilities. We propose a mobility management scheme called personal AP, to support station mobility efficiently. In personal AP mobility support system, the mobility context of each mobile station is defined by the relevant state information at the currently associated access point, including the MAC layer association states at the access point. When the mobile station roams, the access point context follows the mobile station from one physical access point to another, thus creating the \"ghost\" access point following the mobile station and eliminating the mobile station from re-associating with new access points. Personal AP system improve the seamless roaming support by avoid the lengthy re-association process commonly seen in IEEE 802.11 systems. The essential idea of personal AP is applicable in other wireless systems as well.","PeriodicalId":129488,"journal":{"name":"The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125219817","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}

Fitzek et al., (2003), Y-D. Lin et al., (1999), K-C. Wang et al., (2003)] has been recently proposed to extend the coverage area of a base station. However, with selfish nodes in the network, multihop packet forwarding cannot take place without an incentive mechanism. In this paper, we adopt the \"pay for service\" incentive model, i.e., clients pay the relaying nodes for their packet forwarding service. Our focus in this paper is to determine a \"fair\" pricing for packet forwarding. To this end, we model the system as a market where the pricing for packet forwarding is determined by demand and supply. Depending on the network communication scenario, the market models are different. We classify the network into four different scenarios and propose different pricing mechanisms for them. Our simulation results show that the pricing mechanisms are able to guide the market into an equilibrium state quickly. We also show that maintaining communication among the relaying nodes is important for a stable market pricing.","PeriodicalId":129488,"journal":{"name":"The Second Annual International Conference on Mobile and Ubiquitous Systems: Networking and Services","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121696245","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}
