Nodes are classified as sensor nodes and routers. Some nodes act both as sensors and routers. While traditional MAC protocols must balance between throughput, delay, and fairness concerns, WSN MAC protocols place an emphasis on energy efficiency as well. Schedule-based MAC protocols have been proposed for WSN. A common theme through all these protocols is putting radios to a low-power \"sleep mode\" either periodically or whenever possible when a node is neither receiving nor transmitting. In this paper, we investigate the performance of the Neighbor-Aware Clusterhead (NAC) under different sleep scheduling protocols. We study the characteristics and performance of the NAC protocol by means of simulation. In NAC protocol, nodes are synchronized with their clusterheads and are allowed to go into asleep mode. The simulation provides a promising results that makes NAC protocol to be considered as a good candidate protocol for sensor network (SNET).","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123638805","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 proposed method can schedule both streaming applications and non-streaming applications effectively at the same time, since it selects the most suitable networks for the communications of tasks and considers the changing loads of the networks. The experimental results show the proposed method reduced the total execution time of a practical streaming application. The dispersion of the execution time was also suppressed even if the network bandwidth was dynamically changing. This characteristic is very important when this method is applied to more complicated task scheduling methods.","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114381107","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}

Service Level Agreements (SLAs) are powerful instruments for describing such contracts. SLA-aware resource management is the foundation for realizing SLA contracts within the Grid. Open CCS is such an SLA-aware RMS, using transparent checkpointing to cope with resource outages. It generates a compatibility profile for each checkpoint dataset, so that the job can be resumed even on resources within the Grid. However, only a small number of Grid resources comply to such a profile. This paper describes the concept of virtual execution environments and how they increase the number of potential migration targets.The paper also describes how these virtual execution environments have been implemented within the Open CCS resource management system.","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"636 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123962264","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 this paper, we present a novel design for a dual-mode user equipment (UE) model that supports both 3G and Wi-Fi access and provide one implementation using the OPNET simulation tool. The proposed UE model should be capable of supporting all the integrated network architectures depending on the deployment scenario. The modular model is equipped with two air-interface modules that allow communication with 3G and Wi-Fi networks, but the rest of the protocol stack is the standard IP protocol stack to satisfy the compatibility requirement. The design also includes needed functionalities to support vertical handoff across the two networks. The paper also presents an example algorithm that may be implemented into the proposed UE for enhanced gateway selection.","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116609628","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 meetings of human societies, agreement procedures are so flexible that persons can change their opinions and can use not only all-condition but also various types of agreement conditions like majority-condition. In this paper, we discuss a flexible agreement protocol of multiple peers by taking into account human behaviors. In order to model the social human behavior, we already discuss existentially and preferentially precedent relations which shows that a peer can take a value after taking the other one and prefer one value to others, respectively. If a peer autonomously takes values based on its precedent relations, the peers might not make an agreement even if there exists a satisfiable set of values. We discuss what previous values the peers can take again. In this paper, we try to find a satisfiable set named cut of previous values in a history of values which the peers have so far taken, in addition for each peer to taking a new value at each round.","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124692519","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 particular, it is important to enable flexible and secure communications among groups of stationary nodes, such as sensor nodes that collect information about the battlefield, and mobile nodes that operate in the same environment, such as solders, vehicles, and so on. The security of information in such highly dynamic environment is paramount. Therefore, we have developed a new security scheme based on key distribution among stationary sensor and ad hoc networks, and mobile nodes. Our scheme is based on key predistribution using a large key pool, which is segmented into smaller key pools. Each of these segments acts as the key pool for different stationary sensor networks. The mobile nodes get keys from the aggregate of all these segments. The aggregate key pool can have some segments which can be used for future deployments. We have performed extensive analysis and simulations to validate the proposed scheme.","PeriodicalId":231042,"journal":{"name":"2008 International Conference on Parallel Processing - Workshops","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127027723","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}
