As most of consumer electronics are connected to the Internet, network attacks can cause massive damage and loss of data to the users. By sending periodic packet bursts to bottleneck routers, Low-Rate Denial-of-Service (LDoS) attacks can degrade the throughput of TCP applications while being hard to be detected. In this paper, we introduce Power Spectrum Density Entropy (PSD-entropy) to detect LDoS...
Data availability is a major challenge faced by today's Data Centers where a large number of high performance servers are organized into racks interconnected by a switching network. Data replication is an effective approach for data protection as redundancy ensures at least one copy of data is available in the event of failures. To achieve low latency and high throughput for data replication operations,...
Abstract-In this paper we propose MaxCD - a joint multi-flow scheduling and cooperative downloading protocol for drive-thru networks, with the goal of maximizing the amount of data packets that can be downloaded per drive-thru. Based on the macro-level opportunistic scheduling and node cooperation, the best wireless link(s) (with the highest data rate) between the roadside unit (RSU) and vehicular...
In a wireless domain where a mobile user accesses heterogeneous wireless technologies with multiple interfaces, a multi-path scheduling algorithm can benefit mobile users' experience by aggregating different network bandwidth together. However, existing literature actually shows that for TCP flows, it may not be the case. To better exploit multi-path scheduling for TCP connections, this paper presents...
A contention-tone-based wireless local area network (WLAN) protocol uses out-of-band signaling for contention resolution to achieve efficient medium access. It is shown that such a protocol can operate at near-optimal channel utilization in the medium access control (MAC) layer. This paper addresses the service differentiation design aspect of a contention-tone-based WLAN protocol. In particular,...
Cooperative communication techniques have earlier been applied to design of the IEEE 802.11 medium access control (MAC) and shown to perform better. High rate stations can help relay packets from low-rate stations resulting in better throughput for the entire network. However, this also involves additional energy costs on the part of the relay which can result in reducing the network lifetime. We...
In this paper, we propose a framework to enhance user perceived quality in a multihomed terminal. Based on the observed media independent handover parameters from all the interfaces, the terminal is made aware of the performance of the different access networks and it can intelligently select the interface to send out the data packets. Several schemes, for the purpose of load balancing, are defined...
Significant throughput degradation of multihop path communication in wireless mesh network is one of the major problems in wireless communication. The main reason for the lack of bandwidth is channel interference, which is caused by contention for the shared channel between wireless nodes. The natural approach to overcome this problem is exploiting the availability of multiple channels multiple interfaces...
In this paper, we propose a mobility management scheme with quality-of-service(QoS) support for heterogeneous multihomed mobile node. With this scheme, the multihomed mobile node can move between networks seamlessly and at the same time, utilize all available links based on the QoS requirement. Session initiation protocol(SIP)[l] is used in session management and each multihomed node is identified...
