a Dynamic Routing Protocol supporting mobile nodes in wi sun fan systems
Wireless Personal Multimedia Communications, 2017Co-Authors: Thidarut Junjalearnvong, Ryota Okumura, Keiichi Mizutani, Takuya Habara, Hiroshi HaradaAbstract:Wireless Smart Utility Network (Wi-SUN) has been standardized to provide Machine-to-Machine (M2M) communication in Low power and Lossy Networks (LLNs). Wi-SUN Field Area Network (FAN) is the specification that maintains a wireless multi-hop communication on the advanced smart city infrastructure. Wi-SUN FAN has adopted the Internet Protocol version 6 (IPv6) Routing Protocol for LLNs (RPL) which has been successfully optimized in fixed terminals. To establish the embedded smart city, mobile nodes are required to implement the RPL as well. Nevertheless, the RPL fails to choose the appropriate Routing node when the terminal moves, resulting in high packet loss. To improve the transmission performance, the system simulator of Wi-SUN FAN with the Expected Transmission Count (ETX) based algorithm is firstly developed to evaluate the end-to-end transmission success rate via multi-hop transmission and the simulation result clarifies that the critical factor causing low transmission performance is the unsmooth handover of the receiver node at first hop. Then, a Dynamic Routing algorithm based on ETX transition is proposed and the simulation result finally assures the smooth handover, resulting in the improved transmission performance.

data relevance Dynamic Routing Protocol for wireless visual sensor networks
International Conference on Digital Signal Processing, 2013Co-Authors: Petros Spachos, Dimitrios HatzinakosAbstract:Survivability is crucial in Wireless Visual Sensor Networks (WVSNs) especially when they are used for monitoring and tracking applications with limited available resources. In this paper we are proposing the use of a data relevance Dynamic Routing Protocol that tries to keep a balance between the energy consumption and the packet delay in a WVSN. The proposed Dynamic Routing Protocol follows opportunistic Routing approaches. The next node selection criterion can change the Routing path Dynamically following the network conditions and the channel availability while the energy consumption per node is also considered. Simulation results are presented that show an increase in network lifetime of up to 30% compared with traditional Routing while the overall packet delay remains similar.

scalable Dynamic Routing Protocol for cognitive radio sensor networks
IEEE Sensors Journal, 2014Co-Authors: Petros Spachos, Dimitrios HantzinakosAbstract:Wireless sensor networks (WSNs) have been increasingly considered an attractive solution for a plethora of applications. The low cost of sensor nodes provides a mean to deploy large sensor arrays in a variety of applications, such as civilian and environmental monitoring. Most of the WSNs operate in unlicensed spectrum bands, which have become overcrowded. As the number of the nodes that join the network increases, the need for energy-efficient, resource-constrained, and spectrum-efficient Protocol also increases. Incorporating cognitive radio capability in sensor networks yields a promising networking paradigm, also known as cognitive radio sensor networks. In this paper, a cognitive networking with opportunistic Routing Protocol for WSNs is introduced. The objective of the proposed Protocol is to improve the network performance after increasing network scalability. The performance of the proposed Protocol is evaluated through simulations. An accurate channel model is built to evaluate the signal strength in different areas of a complex indoor environment. Then, a discrete event simulator is applied to examine the performance of the proposed Protocol in comparison with two other Routing Protocols. Simulation results show that when comparing with other common Routing Protocols, the proposed Protocol performs better with respect to throughput, packet delay, and total energy consumption.

Black-box Measurement Method of OSPF Performance
Computer Engineering, 2003Co-Authors: Liu GangAbstract:OSPF (open shortest path first) is a widely used Dynamic Routing Protocol in IP networks. Internal processing delays in OSPF implementations impact the speed at which updates propagate in the network, the load on individual routers, and so on. An OSPF user has no access to the software implementation, and also no way to estimate these delays directly. This paper presents a black-box method for estimating delays of key internal tasks in OSPF, includes delay of link-state advertisements, time of calculating shortest path and time of updating forward information base, Thcse can help to maintain network.
