Additionally, TCP suffers because it is unable to distinguish segment loss either due to route failures or due to congestion. Sometimes, TCP misinterprets wireless error as congestion. Another major issue of MANET relates to routing. Aiming at performance enhancement in MANET, we present a cross-layer solution that deals with increased RTT and congestion, and removes false interpretation of link failure due to node movement. We modify lower layer and use link stability information. We modify TCP New Reno to improve TCP performance. We involve DSDV and AODV routing protocol in our study. Along with this, we analyze performance of both actual and modified TCP New Reno implementations in term of Packet Delivery Fraction and Throughput.","PeriodicalId":166718,"journal":{"name":"2012 2nd IEEE International Conference on Parallel, Distributed and Grid Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129430255","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 all know that the biggest threat to the availability of internet is Distributed Denial of Service (DDoS) attack. The objective of DDoS attack is to consume the target's resources to such an extent that it becomes incapable to serve legitimate clients. Till date, a wide variety of solutions have been proposed to solve this problem but a very few of them concentrate on protecting critical infrastructures. Secure Overlay Services (SOS) architecture acts as a basis to protect all these time critical applications. It proactively prevents the target by providing layers of security between the authenticated client and the protected target. Although SOS architecture is successful in complicating the job of attacker, but still it is vulnerable to various attacks. Various researchers critically study this architecture and discuss various attacks possible on it. The aim of this paper is to review various attacks possible on this architecture so that more detailed understanding of attacker's strategy can be achieved and use this knowledge to develop more robust solutions.","PeriodicalId":166718,"journal":{"name":"2012 2nd IEEE International Conference on Parallel, Distributed and Grid Computing","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127652077","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, effect of change in rate of genetic algorithm operator on fitness value in composition of signatures for misuse intrusion detection system is presented. The proposed genetic algorithm uses a set of classification rules which are generated from a predefined intrusion behavior. From the results it could be concluded that if crossover performed is not sufficient, there is not sufficient sharing of genes. If we crossover too much, good segments of individuals get split up a lot. This allows some individuals with high fitness's to be copied directly to the next population.","PeriodicalId":166718,"journal":{"name":"2012 2nd IEEE International Conference on Parallel, Distributed and Grid Computing","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124428402","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}

There are various sequential searching algorithms to search an element in an unsorted array or sorted array of elements. A number of researchers have explored methods for improving the efficiency and speedup of search using parallel hardware, for eg. A 2-D Mesh of Processors can be used to solve various searching problems in O(n1/2) time regardless of any assumption about wire delay. We proposed an algorithm for searching on Hypercube Interconnection network that solves the basic query problem, namely given an integer x, it is required to search a file of records on the s field for x.

In recent years many routing protocols have been proposed after considering the particular VANET characteristics. We have rigorously studied the proposals and then came up with the conclusion that protocols based on the vehicles positions were found to be the most adequate to VANETs due to the flexibility criterion of handling the nodes position variations. We propose the novel protocol which provide the solution for existing position based routing protocol with help of our test bed and algorithms.","PeriodicalId":166718,"journal":{"name":"2012 2nd IEEE International Conference on Parallel, Distributed and Grid Computing","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115435979","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}

Switched fabric can be a fast and reliable hardware solution for existing CAN-bus limits. In fact, it allows multiple packets to be transferred simultaneously ensuring sufficient bandwidth. To resolve this problem when keeping the use of CAN protocol, we remove the CAN access technique module from an existing VHDL implementation of a CAN controller component and we replace it by a crossbar switched fabric, implemented in VHDL also. In this paper, we designed a Crossbar switched fabric CAN based on VHDL modules and we simulated it under ModelSim tools and we give of proof-of-concept of a CAN controller based on crossbar switched fabric.","PeriodicalId":166718,"journal":{"name":"2012 2nd IEEE International Conference on Parallel, Distributed and Grid Computing","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115820723","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}

So, the major issue is to reduce the computation cost by implementing some optimization technique, so that the overall efficiency of the system increases without any loss of information.
