However, sensor size represents a significant limitation mainly in terms of energy autonomy and therefore of life period, for the batteries have to be too tiny. This is the reason why intensive research is being conducted nowadays on how to control sensor energy consumption within a network, taking communications into account as a priority. For this purpose we have proposed a method to calculate energy consumption within the wireless sensor networks, according to the number of information packets sent, the number of nodes. Furthermore, we have succeeded in reducing energy consumption within the sensor networks made up with nodes featuring differing data flow rates.","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121017568","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}

Its specific application by the Accent project to call control is then discussed. The Appel policy language supports regular policies as well as resolution policies that deal with conflict handling. The core Appel language can be specialised, e.g. for call control. Ontologies are introduced as a means of capturing domain-specific knowledge - here, about calls. It is seen how this has allowed the Accent policy system to be generalised for use in a variety of domains. This is supported by a stack of interrelated ontologies: for generic policy aspects, for a policy definition wizard, and for call control. The approach has been integrated with the Accent system, allowing its extension for policy-based management in new domains.","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129749385","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 is based on two mechanisms including route discovery and route maintenance. In highly dynamic networks, the surplus use of expired routes in the cache of DSR increases the latency and the frequent diffusion of route request packets consumes bandwidth. Consequently, DSR presents handicap in terms of end- to-end delay and overhead. In this paper, we propose a new routing protocol, called Ant-DSR, which implements a distributed topology discovery mechanism through mobile agents to maintain DSR cache. Implemented and simulated on ns-2, Ant-DSR shows a better resistance in high mobility and huge load environments in comparison to DSR.","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"314 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116080208","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}

Packet traces can provide information about the performance experienced by flows and other characteristics of the traffic, such as packet sizes, packet loss, one way delay and delay variation. We used the well-known database MySQL to store and retrieve data. The meter/exporter and collector process were implemented in the Linux operating system environment.

Typically, in ad hoc networks, priority is given to routing packets over data packets and data packets are served in first-in-first-out (FIFO) bases. In this paper, for an inter-vehicular mobile ad hoc network, we introduce data packets' queue priority equal to that of routing packets, based on the driving direction of the data packets' source and destination. The ad hoc on demand distance vector (AODV) protocol is used as the routing protocol in this work. Simulation results of 200 vehicles driving at speeds between 61 tilde119 km/h on a 2-lane motorway demonstrate a performance increase in data packet delivery ratio and decrease in average end-to-end packet delay and routing overhead for the proposed algorithm.","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"49 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132241255","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}

The state of the buffer can be represented by a discrete Markov chain defined on a large state space size O(B3).

Grout","doi":"10.1109/AICT.2007.16","DOIUrl":"https://doi.org/10.1109/AICT.2007.16","url":null,"abstract":"Various researchers have reported that traffic measurements demonstrate considerable burstiness on several time scales, with properties of self-similarity. Also, the rapid development of technologies has widened the scope of network and Internet applications and, in turn, increased traffic. The self-similar nature of this data traffic may exhibit spikiness and burstiness on large scales with such behaviour being caused by strong dependence characteristics in data: that is, large values tend to come in clusters and clusters of clusters and so on. Several studies have shown that TCP, the dominant network (Internet) transport protocol, contributes to the propagation of self-similarity. Bursty traffic can affect the Quality of Service of all traffic on the network by introducing inconsistent latency. It is easier to manage the workloads under less bursty (i.e. smoother) conditions. In this paper, we introduce a novel algorithm for traffic shaping, which can smooth out the traffic burstiness. We name it the Bursty Packet Traffic Shaper (BPTraSha). Experimental results show that this approach allows significant traffic control by smoothing the incoming traffic. BPTraSha can be implemented on the distribution router buffer so that the traffic's bursty nature can be modified before it is transmitted over the core network (Internet).","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114366164","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}

The estimation is performed by extracting the parameters of the channel impulse response. The channel impulse response is obtained by cross-correlation between the pilot symbols known at the receiver and the portion of the received signal which hold emitted pilot symbols. Channel estimation errors, and more particularly the false-path detection, damages the performances of coherent receiver. To avoid the false-path detection, we introduce a novel criterion which depend on signal-to-noise ratio and cross- correlation imperfections. The simulation results reveal optimum thresholds to have a better channel estimation.","PeriodicalId":334924,"journal":{"name":"The Third Advanced International Conference on Telecommunications (AICT'07)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117040738","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}
