Over the past few years, a variety of new routing protocols have been proposed, but the performance evaluation of each protocol shows variable results according to network parameters such as throughput, scalability, mobility and topology variation. Hence, it is challenging to find one single universal protocol or any adaptive protocol to meet all the network topology conditions, mobility patterns and scalability requirements. So, if protocols are dynamically allocated to the router nodes then it is possible to obtain an all time high throughput programmable router. Many MANET applications benefit from increased throughput, which is the focus of this work. Therefore, in this paper, a new method of dynamic reconfigurable routing (DRR) using two reactive on demand protocols viz. DSR and AODV is proposed. The DRR router monitors the throughput continuously and when the throughput plunges down below the acceptance value, it adapts to different protocol to maintain the throughput. The change of protocol to the router is done by modifying the config. in file of global mobile simulator (GLOMOSIM)","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126275454","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}

A statistical model of the network activities is built using the payload and is trained with the normal behavior of user(s) in the network over a period of time. This model in-turn is used to detect deviations that are high from the expected behavior which indicate a security breach or a possible attack. The payload of the network traffic is analyzed by the system in an unsupervised manner and then classifies as normal traffic during training phase. The value-byte frequency of the application payload is calculated for each normal packet based on payload length and port number. The Mahalanobis distance and a similarity measure is then used to measure the similarity of the incoming data with the already computed values in the detection phase. This distance is then compared against a threshold value and generates an alert if it exceeds the value. In the clustering phase we provide a method to reduce the resource consumption which can easily update the stored profile using an incremental algorithm and the model is continuously updated so that it is accurate. The modeling method that is being followed is completely unsupervised and also tolerant to noise in the training data. The method proposed is also resistant to mimicry-attack. This system is designed to be integrated into other detectors in order to mitigate false positive rates so that this enriches the chances of detecting zero-day worms and new attack exploits","PeriodicalId":257948,"journal":{"name":"2007 International Conference on Signal Processing, Communications and Networking","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125857985","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}
