Performance Study of Fluid Content Distribution Model for Peer-to-Peer Overlay Networks (WiMoA 2011 and ICCSEA 2011)

Abstract Recently overlay networks are used to serve high-concurrency applications ranging from live streaming to reliable delivery of popular content. Comparing to traditional communication mechanism overlay networks offer an enhanced alternative for content delivery in terms of flexibility, scalability, and ease of deployment. Content distribution process in overlay networks is facilitated by leveraging the uploading […]

The Hybrid Cubes Encryption Algorithm (HiSea) (WiMoA 2011 and ICCSEA 2011)

Abstract Hybrid cubes are generated from a combination and permutation of integers as shown in Latin squares and orthogonal Latin squares. In this paper we extend our earlier non binary block cipher using all possible combination of hybrid cubes layers as the source for the encryption and decryption keys. The overall security of the cipher […]

Reducing Handover Latency in Mobile IPv6-Based WLAN by Parallel Signal Execution at Layer 2 and Layer 3 (WiMoA 2011 and ICCSEA 2011)

Abstract The emergence of wireless networking demands continuous connectivity to support end-to-end TCP or UDP sessions. Wireless networking does not provide reliable connections to mobile users for realtime traffic such as voice-over IP, audio streaming and video streaming. Handover latency in Mobile IPv6 is one factor that disconnects users while roaming. Most of the proposed […]

Minimization of Boolean Functions Which Include Don’t-Care Statements, Using Graph Data Structure (WiMoA 2011 and ICCSEA 2011)

Abstract In this paper, we intend to introduce a heuristic algorithm to apply maximum minimization to Boolean functions with normal SOP form. To implement the proposed algorithm, we use the graph data structure and define the adjacencies. Also, we demonstrate some conditions to achieve the maximum minimization. Through this paper, the problem of shared vertices […]

Clustering Moving Object Trajectories Using Coresets (WiMoA 2011 and ICCSEA 2011)

Abstract Given a set of moving objects, we show the applicability of using coresets to perform fast approximate clustering. A trajectory coreset is simply a small weighted set of the trajectory segments that approximates the original trajectory. In this paper, we present an efficient algorithm that integrates coreset approximation with k-means clustering. Our methodology to […]

ASIC Architecture to Determine Object Centroids from Gray-Scale Images Using Marching Pixels (WiMoA 2011 and ICCSEA 2011) Part 1

Abstract The paper presents a SIMD architecture to determine centroids of objects in binary and gray-scale images applying the Marching Pixels paradigm. The introduced algorithm has emergent and self-organizing properties. A short mathematic derivation of the system behavior is given. We show that a behavior describing the computation of object centroids in gray-scale images is […]

ASIC Architecture to Determine Object Centroids from Gray-Scale Images Using Marching Pixels (WiMoA 2011 and ICCSEA 2011) Part 2

Local Datapath The local data path of the MP architecture is characterized by orthogonal serial data connections between the CUs. In figure 6 a CU black box representation is shown. The figure depicts all neighboured input data to compute the y-coordinate of the object’s centroid. Fig. 6. Data inputs of the Flooding-CU Note 3. For […]

Learning Digital Cashless Applications with the Consolidation of Authenticity, Confidentiality and Integrity Using Sequence Diagrams (WiMoA 2011 and ICCSEA 2011)

Abstract Recent surges in e-cashless transactions, attacks and intrusions reflect vulnerabilities in computer networks. Innovative methods and tools can help reinforce defenses, prevent attack propagations, detect and respond to such attacks. We have been experimenting with methods for introducing important concepts related to e-cashless transactions and improving undergraduate curricula and research experiences for Computer Science […]

Encoding in VLSI Interconnects (WiMoA 2011 and ICCSEA 2011)

Abstract This paper reviews different encoding schemes for reduction of power dissipation, crosstalk noise and delay. The encoding scheme is categorized based on the type of encoding methods and their power, delay reduction capability with crosstalk avoidance. Crosstalk is aggravated by enhanced switching activity which is frequently main reason for the malfunctioning of any VLSI […]

Vertical Handover Efficient Transport for Mobile IPTV (WiMoA 2011 and ICCSEA 2011) Part 1

Abstract The success of IPTV suggests that an expansion to mobile devices is likely. A key difference between IPTV delivery to mobile devices and broadband access is the possibility of vertical handovers, which can cause disruption to real-time video streaming. This paper proposes a lightweight form of IPTV transport based on negative acknowledgments. The performance […]
