Disruption-tolerant network (DTN) technologies are becoming successful solutions that allow nodes to communicate with each other in these extreme networking environments. Typically, when there is no end-to-end connection between a source and a destination pair, the messages from the source node may need to wait in the intermediate nodes for a substantial amount of time […]
WIRELESS AD HOC NETWORKS WITH A NOVEL NCAC-MAC PROTOCOL
Network coding is an interesting technique which can provide throughput improvements and a high degree of robustness in packet networks. Network coding is a networking technique in which transmitted data is encoded and decoded to increase network throughput, reduce delays and make the network more robust. Cooperative communication, which utilizes neighboring nodes to relay the […]
INCREASE THROUGHPUT AND REDUCE DELAY IN WIRELESS AD HOC NETWORKS USING NCAC-MAC PROTOCOL
The broadcast nature of the wireless medium (the so-called wireless broadcast advantage) is exploited in cooperative fashion. The wireless transmission between a transmitter-receiver pair can be received and processed at neighboring nodes for performance gain, rather than be considered as the interference traditionally. Network coding, which combines several packets together for transmission, is very helpful […]
MEASURING THE RISK OF UNKNOWN VULNERABILITIES USING K-ZERO DAY SAFETY NETWORK SECURITY METRICS
we propose a novel network security metric, k-zero day safety, to address this issue. Roughly speaking, instead of attempting to measure which un-known vulnerabilities are more likely to exist, we start with the worst case assumption that this is not measurable. Our metric then simply counts how many zero-day vulnerabilities are required to compromise a […]
PREDICTIVE ACK BASED CLOUD BANDWIDTH AND COST REDUCTION SYSTEM
Traffic redundancy stems from common end-users’ activities, such as repeatedly accessing, downloading, uploading (i.e., backup), distributing, and modifying the same or similar information items (documents, data, Web, and video). TRE is used to eliminate the transmission of redundant content and, there-fore, to significantly reduce the network cost. In most common TRE solutions, both the sender […]
MULTILEVEL INTER- RELATIONSHIP GRAPH FOR KEYWORD QUERY ROUTING
Conventional keyword search engines are restricted to a given data model and cannot easily adapt to unstructured, semi-structured or structured data. Keyword search is an intuitive paradigm for searching linked data sources on the web. We propose to route keywords only to relevant sources to reduce the high cost of processing keyword search queries over […]
KEYWORD QUERY ROUTING FOR KEYWORD SEARCH OVER A LINKED DATA SOURCES
This abstract proposed to identify data sources that contain results to a keyword query. The goal is to produce routing plans, which can be used to compute results from multiple sources. Keyword search is an intuitive paradigm for searching linked data sources on the web. We propose to route keywords only to relevant sources to […]
DEFENSE AND DETECTION OF BWDDOS ATTACK
A denial-of-service (DoS) or distributed denial-of-service (DDoS) attack is an attempt to make a machine or network resource unavailable to its intended users. The Internet is vulnerable to bandwidth distributed denial-of-service (BW-DDoS) attacks, wherein many hosts send a huge number of packets to cause congestion and disrupt legitimate traffic. Bandwidth DDoS (BW DDoS) attacks disrupt […]
LOCATION-BASED SEARCH QUERIES USING EXPLOITING SERVICE SIMILARITY FOR PRIVACY PRESERVING
LBS include services to identify a location of a person or object, such as discovering the nearest banking cash machine (a.k.a. ATM) or the whereabouts of a friend or employee. LBS include parcel tracking and vehicle tracking services. LBS can include mobile commerce when taking the form of coupons or advertising directed at customers based […]
SERVICE SIMILARITY EXPLOITING IN LBS QUERIES FOR PRIVACY
Location-based services (LBS) are a general class of computer program-level services that use location data to control features. As such LBS is an information service and has a number of uses in social networking today as an entertainment service, which is accessible with mobile devices through the mobile network and which uses information on the […]
