These environments and everyday objects will be equipped with small, inexpensive, and low power devices having capability to communicate with each other in order to organize and coordinate their actions. Computation will be freely available everywhere allowing us to perform tasks anywhere at anytime. The individuals will be equipped with lightweight devices instead of heavy devices that condense the effectiveness of individual. Furthermore, there is increasing trend towards anytime, anywhere computing paradigm that allow user to work at home, while traveling or at any location. Due to this increasing trend and availability of hundreds of low constrained devices, it will be possible for individuals to form a mobile ad hoc computational grid by integrating piecemeal devices into a single, unified computing resource that could achieve the desired result. The purpose of study is to propose architecture for mobile ad hoc computational grid for low constraint devices in order to perform high processing tasks.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128574377","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 a challenge to meet the changing resource requirements of the threads by making resource allocation according to limited pipeline information. To avoid the stagnation of resource allocation optimization in the local suboptimal resource distributions and perform quick capture on the new optimal resource distributions, this paper proposes a dynamic resource allocation optimization (DRAO) for SMT processors, which optimizes the resource allocation targeting only the throughput performance. An optimization model with consideration of both throughput and fairness performance is designed for DRAO to steer the exploitation on historical allocation and the exploration on new allocation solutions. Results from experiment show that DRAO obtains potential improvement of fairness performance as well as good improvement of throughput performance. These are attributed to the well-balanced exploitation and exploration activities.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128835011","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 future switch should perform high speed switching, eliminate the implementation of buffers, transparent packet format and allows multiple user access. Thus, the development of a heuristic approach that handles multi protocol label swapping (MPLS) and supports all optical label swapping (AOLS) routing protocols via the implementation of optical code division multiple access (OCDMA) datagram is necessary. Consequently, to prepare for contention conditions, WDM can be integrated with OCDMA that offers more channels and network capacity. It harnesses enormous bandwidth by coupling multiple wavelengths into a single fiber. This should reduce the probability of packet loss due to contention. Furthermore, the orthogonal code and label swapping enhance the network throughput. Also, this paper investigates the possibility of the realization of WDM/OCDMA and the simulation results from the preliminary study are compared with the conventional approaches. Relatively, the work is aimed to characterize all components making up the router/switch that consists of the multiplexer, demultiplexer, encoder and decoder. Several relevant issues and the limitations are discussed by considering the features and requirements aforementioned.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114777535","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}

These nodes connect to each other and form multi-hop networks. These networks are used for various applications such as habitat monitoring, automation, and agriculture. Almost all the existing sensor networks focus on homogenous sensor networks. Homogenous sensor networks are identical sensors with equal capacity in term of sensing, computation, communication and power. But homogeneous sensor networks have poor performance in terms of energy consumption and end-to-end delay. It is also difficult to work with more than one type of sensors within a same network. So it is required to analyse the heterogeneous sensor networks (HSN) model for better performance. Simulation results prove that heterogeneous sensor networks outperform the homogeneous sensor networks in terms of energy consumption, end-to-end delay and delivery ratio with different node capability.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131281563","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 these circumstances IMS has emerged out as a key player. IMS is basically a network architecture consisting of an IP-based core network connected to multiple access networks to provide a converged service to wireless,wireline and cable subscribers. IMS has established itself as a foundation for future wireless and wireline convergence. It provides an opportunity to build an open IP based service platform that will enable an easy and efficient deployment of new multimedia communication services mixing telecom and data services. One thing which really makes a difference is that a common IMS based service platform can be used to serve various access mechanisms such as WiMAX, WiFi, UMTS,GSM, CDMA etc. IMS fills the gap between two of the most successful communication paradigm cellular and internet technology.

The Pareto-frontier Differential Evolution (PDE) algorithm is used to generate the Pareto optimal sets of ANNs that optimize the conflicting objectives of maximizing the virtual Khepera robot’s behavior for homing towards a RF signal source and minimizing the number of hidden neurons used in its feed-forward ANNs controller. A fitness function used for mobile robot RF-localization behavior is proposed. The experimentation results showed the virtual Khepera robot was able to navigate towards signal source with using only a small number of hidden neurons. Furthermore, the Pareto-frontier solutions have been utilized for robustness testing purposes in the environment differs as that used during evolution. The results showed the PDE-EMO algorithm can be practically used in generating the required robot controllers for RF-localization behavior.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127853378","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}

Target tracking is able to widen the perspective and view of the static camera to track a target, providing basic artificial intelligence features for robots, and serve as the platform for surveillance purpose. A tracking system is limited to a monocular vision which limits much of the information that is available in an image compared to a binocular or stereo vision. Among the advantages of stereo vision is 3D modeling of scene and depth estimation. In this work, an initial development study and implementation of stereo vision tracking system was done. In developing the stereo vision tracking system, a tracking algorithm was developed together with a depth estimation method to take advantage of the images obtained from having images from two cameras. The depth estimation was found to be 80% accurate for objects at a distance of 15 cm to 65 cm from the cameras.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134052266","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}

Among the wireless networks, wireless ad hoc networks have been popular because they are very easy to implement without using base stations. Transmission Control Protocol (TCP) and routing protocols (DSR, DSDV, AODV, etc) as well as link layer protocols are becoming as an essential part of communication between two or more communication hosts. In theory, transport protocols should be independent of the technology of the underlying network layer. However, in practice, TCP, as a standard transport protocol for Internet, is tuned for wired network and performs poorly in wireless networks. Therefore, many researchers invented the different variants of TCP over wired and wireless network. In this paper, we analyze how the variants of TCP suffer from packet losses and average end-to-end delay over each routing protocol, and measure the throughput of received packets in static and mobile ad hoc environments.","PeriodicalId":338489,"journal":{"name":"2009 International Conference on Future Computer and Communication","volume":"333 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131474880","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}
