Masquerading and eavesdropping are major threats to the security of wireless communications and mobile networks. To provide proper protection for the communication of the wireless link, the contents of the communication should be enciphered and mutual authentication should be conducted between the communicating nodes. Authentication protocols and key management techniques play a vital role and are the basis of security in many distributed systems. Much research has been conducted into the development of key management techniques and authentication protocols for WLAN (802.11b, 802.11i, 802.15.1, HIPERLAN) and traditional wireless networks (GSM, UMTS). This paper specifically describes the fundamental limitations of these underlying techniques and protocols and discusses why they cannot be directly employed in mobile ad hoc networks (MANETs). To the best of the authors' knowledge, this is the first paper which collectively addresses the limitations of the security mechanisms used in existing wireless networks for MANETs","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126126805","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}

With on-board processing, a satellite can process the received data, and according to the nature of application, it can decide on the transmission properties. Specifically, considered OBP includes error-correcting coding to combat adverse channel conditions and priority queueing mechanisms for efficient use of the system resources. After a brief overview of relevant aspects of satellite networks to VoIP, the VoIP performance for non-geostationary Earth orbit (NGEO) single layer and multi-layered constellations are examined using a network simulation tool. The outcome of these simulations justifies the premise for the multi-layered architecture for delay-sensitive and real-time traffic such as voice. Subsequently, the effects of some quality-of-service (QoS) mechanisms in multi-layered architecture are tested using various simulation parameters. The system simulation verifies that multi-layered satellite networks with OBP capabilities and QoS mechanisms are essential for feasibility of packet-based high quality voice services which are vital components of next-generation communications networks","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"37 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124518484","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}

Reliability properties of these protocols are ensured via probabilistic guarantees. A key issue to consider when offering reliability is the buffer space used by individual peers of the group. Our aim is to optimize the buffer space while providing reliability in epidemic data dissemination protocols. We introduce a novel randomized model and compare it with a hash-based approach for buffer management. The effect of short and long term buffering of peers and the buffer size on delivery latency and reliability are considered.

However, Diffserv does not address control plane functionality. For end-to-end QoS in large-scale Diffserv networks, a control mechanism is needed. The bandwidth broker is the strongest candidate for this. In this paper, we propose a novel route server (RS) architecture, compatible with the BB model, for inter-domain QoS routing. The RS is the only entity that performs both intra-and inter-domain QoS routing in its domain. In particular, the RS has two routing components, interior route server (iRS) responsible for intra-domain QoS routing and exterior route server (eRS) responsible for inter-domain QoS routing. The preliminary implementation results verify the achievements of the proposed architecture","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132042101","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 investigate recovery techniques as bases of useless packet transmission avoidance in order to release bandwidth by avoiding sending unintelligible packets. At times, packet-loss exceeds a given threshold such that recovery techniques are not able to cope with packet-losses. Therefore, algorithms supplying lower latency and higher degree of recovery are needed. Moreover, faster algorithms for generating packets, transmitting, and recovering from losses in the streams, help managing unintelligible flow for the various multimedia streams. Here, we propose the fast forward algorithm (FFA) that removes latency in packet generation, is practical, and is very simple to implement. FFA is equally suitable for interactive and non-interactive applications.

These networks have overlaid coverage areas and are composed of a hierarchical structure ranging from in-room to in-building, campus, metropolitan, and wide-areas. For these networks to work as a seamless inter-working, optimal mobility management has to be implemented. Beside the traditional horizontal handoffs between cells of the same network, vertical handoffs between different networks have more impact on system performances. One of the important challenges for seamless vertical mobility is to maintain a user active connectivity while the user is changing its point of attachment. In this paper we are addressing one aspect of the mobility management, namely the vertical handoff decision problem in wireless overlay networks, in this study, an algorithm is proposed to avoid the unnecessary vertical handoffs for such networks under different circumstances. Simulation results on the key parameters such as grade of service (GoS) and system utilization prove that the proposed strategy can provide powerful support for QoS in wireless overlay networks","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121691236","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}

On the other hand, access networks are continuously improving and it is anticipated that bandwidth demands exponentially increase within next decade to cope with triple-play service requirements. The first level of aggregation, namely metro access networks, can become the bottleneck if no serious modifications are carried out because they were initially designed for circuit-oriented services such as analogical voice transmission and they can not keep up with bandwidth demands at reasonable capital expenditure efforts. In this paper, the authors present a migration roadmap for metro access networks derived from the results of NOBEL, ePhoton/One and FIRM European research projects.
