Minimum Hop vs. Minimum Edge Based Multicast Routing for Mobile Ad Hoc Networks (WiMoA 2011 and ICCSEA 2011)

Abstract The high-level contribution of this paper is to establish benchmarks for the minimum hop count per source-receiver path and the minimum number of edges per tree for multicast routing in mobile ad hoc networks (MANETs) and explore the tradeoffs between these two routing strategies with respect to hop count, number of edges and lifetime […]

Implementing Recovery in Low-Resource Stationary Wireless Sensor Networks (WiMoA 2011 and ICCSEA 2011)

Abstract Implementation of certain types of protocols on wireless sensor networks (WSNs) can be difficult due to the architecture of the motes. Identification of these issues and recommendations for workarounds can be very useful for the WSN research community testing hardware. In recent work, the authors developed and implemented clustering, reprogramming and authentication protocols involved […]

Trusted Third Party Synchronized Billing Framework Using Multiple Authorizations by Multiple Owners (MAMO) (WiMoA 2011 and ICCSEA 2011)

Abstract Numerous applications are envisioned with the proliferation of mobile usage in this decade. Third party billing system for subscription is one of them. Third party billing system needs acquisition of data from both users’ handset and base satiation of the service providers. Trustworthiness and Synchronization are the characteristics that need to be ensured of […]

Random Variation in Coverage of Sensor Networks (WiMoA 2011 and ICCSEA 2011)

Abstract Wireless Sensor networks have become one of the most widely-used forms of ad-hoc networks which have countless number of applications in the modern life. Due to the unreliable communication medium and the failure-prone sensors, coverage is an important functional property of a sensor network. Coverage is represented as a function of sensor density, which […]

A Study of Applying SIP Mobility in Mobile WiMax Network Architecture (WiMoA 2011 and ICCSEA 2011)

Abstract This paper studies cooperation of the ASN anchored mobility and SIP terminal mobility to improve the handoff performance in WiMax network. In addition to integrating the WiMax mobility and SIP mobility procedure by using the B2BUA concept, the proposed scheme investigates the traffic load so that the handoff dropping rate can be reduced. As […]

IEEE 802.15.4/Zigbee Performance Analysis for Real Time Applications Using OMNET++ Simulator (WiMoA 2011 and ICCSEA 2011) Part 1

Abstract Wireless sensor networks (WSN) were been explored in various scenarios and several protocols have been developed. With the standardization of the IEEE 802.15.4 protocol, sensor networks became interesting for application in industrial automation. The IEEE 802.15.4 specifies physical and media access control layers that could be optimized to ensure low-power consumption. The focus in […]

IEEE 802.15.4/Zigbee Performance Analysis for Real Time Applications Using OMNET++ Simulator (WiMoA 2011 and ICCSEA 2011) Part 2

Simulation Parameters We have evaluated the 802.15.4 protocol performances in star topology, where nodes transmit data directly to the coordinator. We considered that the wireless channel is without interferences, so this means that each node is able to hear the transmissions of all the other nodes. The CSMA/CA mechanism uses imply that the messages can […]

Honeynet Based Botnet Detection Using Command Signatures (WiMoA 2011 and ICCSEA 2011)

Abstract Global Internet threats are undergoing a profound transformation from attacks designed solely to disable infrastructure to those that also target people and organizations. This alarming new class of attacks directly impacts the day to day lives of millions of people and endangers businesses and governments around the world. At the centre of many of […]

Bandwidth Probe: An End-to-End Bandwidth Measurement Technique in Wireless Mesh Networks (WiMoA 2011 and ICCSEA 2011) Part 1

Abstract End-to-end Bandwidth Estimation is an important metric for network management and monitoring. It can also improve the effectiveness of congestion control mechanism, audio/video stream adoration and dynamic overlay. In recent years, many techniques have been developed for bandwidth estimation in the wired as well as the last-hop wireless networks, but they under-perform in Wireless […]

Bandwidth Probe: An End-to-End Bandwidth Measurement Technique in Wireless Mesh Networks (WiMoA 2011 and ICCSEA 2011) Part 2

What the Algorithm Really Does In WMNs, dispersion due to both contending and cross traffic are at wireless nodes and access point. So traffic would not be FIFO manner. This causes random delay between two successive packets. Hence, to trace the behavior of WMNs, Bandwidth Probe measures two variables, CEffective and TAchievable. CEffective indicates the […]
