Its main advantage is to avoid the read-write conflicts, i.e. a read operation will never be blocked by a write operation and vice versa. Among existing concurrency control protocols, SI offers the highest degree of concurrency. But SI is known to be non-serializable, that is, in some situations data consistency can be violated through concurrency, even between correct applications. Recently, some extensions of SI protocol have been proposed to make it serializable. However, each of these extensions of SI admits an additional overhead to strengthen serializability. In this work, we explore the impact of the approach based on changing the SI concurrency control mechanism to ensure serializability of executions on performance. To do this, we conduct an experimental study to examine the only serializable variant of SI that is actually in use. This is the implementation of the extension Serializable Snapshot Isolation (SSI) provided in the database management system (DBMS) PostgreSQL.","PeriodicalId":165465,"journal":{"name":"2015 12th International Symposium on Programming and Systems (ISPS)","volume":"25 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125891681","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}

Therefore it should rely on flexible administrative mechanism. An important component of the administrative mechanism is delegation. Delegation is the process of granting a specific authorization from a user to another user of the same system to carry out some functions on his behalf. The delegation, although widely used, is modeled in very little security policies because this concept is very complex. What we tried to do in this work is to redefine delegation for OrBAC using description logic. OrBAC is an access control model; it provides the mean to specify contextual authorizations, which facilitates modeling the features of the delegation such as temporary delegation, multiple delegation, revocation, etc. The description logic that we use for the re-formalization process is T-JClassicδϵ. This logic is a temporal nonmonotonic description logic, it gives the mean to specify nonmonotonic authorizations, and a better representation of the temporal aspects specific to a given delegation. This new representation augments the expressivity of the model and therefore it facilitates even more the representation and the management of the delegation characteristics.","PeriodicalId":165465,"journal":{"name":"2015 12th International Symposium on Programming and Systems (ISPS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125700824","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 information could be seen as user's preferences in a process of flexible query evaluation, which is capable to distinguish amongst the product items those that are the most suitable or most preferred to a given buyer. In this paper, we model product items (or alternatives) attached with positive and negative ratings as intuitionistic fuzzy sets [1], such that positive and negative ratings correspond to membership and nonmembership degrees respectively. Then, we show that available heterogeneous bipolar approaches developed in the field of flexible querying are not adequate in our case, and we introduce two new operators to rank intuitionistic alternatives, namely, Intuitionistic minimum, denoted by Imin, and Intuitionistic maximum, denoted by Imax. Finally, we show that each of these operators forms a linear order and both can represent a couple of extended intuitionistic t-norm and t-conorm that can be used as a basis of an intuitionistic bipolar fuzzy querying approach.","PeriodicalId":165465,"journal":{"name":"2015 12th International Symposium on Programming and Systems (ISPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125533893","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, a novel hierarchical approach called distributed energy efficient adaptive clustering protocol with Data Gathering (DEACP) is proposed for Wireless sensor network. Since nodes in a sensor network have limited energy, prolonging the network lifetime and improving scalability become important. we have proposed (DEACP) approach to reach the following objectives: reduce the overall network energy consumption, balance the energy consumption among the sensors and extend the lifetime of the network, the clustering must be completely distributed, the clustering should be efficient in complexity of message and time, the cluster-heads should be well-distributed across the network, the load balancing should be done well, the clustered WSN should be fully-connected. As a result transmission power of the node is reduce which subsequently reduces the energy consumption of the node. Our proposed work is simulated through Network Simulator (NS-2). We consider the problem of conserving energy in a single node in a wireless sensor network by turning off the node's radio for periods of a fixed time length. While packets may continue to arrive at the node's buffer during the sleep periods, the node cannot transmit them until it wakes up. The objective is to design sleep control laws that minimize the expected value of a cost function representing both energy consumption costs and holding costs for backlogged packets. The network scenario is established by considering 1000 × 1000 area and displaying randomly moving nodes using TCL. The resource reservation is used to decompose the total simulation time of network into smaller time slots depending upon number of nodes in the network using TDMA technique. Simulations show that (DEACP) clusters have good performance characteristics.","PeriodicalId":165465,"journal":{"name":"2015 12th International Symposium on Programming and Systems (ISPS)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122683429","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}
