  • Simulation of Satellite Network Routing Protocol Based on OPNET
    Computer Engineering, 2011
    Co-Authors: Su Jin-hai
    Abstract:

    In modeling satellite Network,Routing simulation is one of the key problems that must be resolved.On the basis of analyzing the features of satellite Routing,a Routing scheme based on plans is proposed.A model is accomplished based on the Internet Protocol(IP) process model of OPNET,and the procedure is discussed in detail.Simulation results show that the Routing simulation scheme can support satellite Network modeling effectively.

  • The Impact of Node Heterogeneity on ZigBee Network Routing
    Handbook on Sensor Networks, 2010
    Co-Authors: Ling-jyh Chen, Li Ping Tung, Tony Sun, Nia-chiang Liang
    Abstract:

    Based on the IEEE 802.15.4 LR-WPAN standard, the ZigBee standard has been proposed to interconnect simple, low rate, and battery powered wireless devices. The deployment of ZigBee Networks is expected to facilitate numerous applications, such as home-appliance Networks, home healthcare, medical monitoring, consumer electronics, and environmental sensors. An effective Routing scheme in a ZigBee Network is particularly important in that it is the key to achieve resource (e.g., bandwidth and energy) efficiency in ZigBee Networks. Routing in a ZigBee Network is not exactly the same as in a MANET. In particular, while Full Function Devices (FFD) can serve as Network coordinators or Network routers, Reduced Function Devices (RFD) can only associate and communicate with FFDs in a ZigBee Network. Therefore, different from traditional MANET Routing algorithms, which only take into account node mobility to figure out a best route to a given destination, node heterogeneity plays an important role in ZigBee Network Routing. In this chapter, we firstly perform extensive evaluation, using NS-2 simulator, to study the impact of node heterogeneity on ZigBee mesh Network Routing. The results show that the ZigBee mesh Routing algorithm exhibits significant performance difference when the Network is highly heterogenous. Then, we study the mesh Routing and its support of device mobility with different mobility cases. Under a rich set of preliminary tests, our results indicate that ZigBee device type plays a significant role in determining the Routing performance in most mobile scenarios.

  • virtual ring Routing Network Routing inspired by dhts
    ACM Special Interest Group on Data Communication, 2006
    Co-Authors: Matthew Caesar, Miguel Castro, Edmund B Nightingale, Greg Oshea, Antony Rowstron
    Abstract:

    This paper presents Virtual Ring Routing (VRR), a new Network Routing protocol that occupies a unique point in the design space. VRR is inspired by overlay Routing algorithms in Distributed Hash Tables (DHTs) but it does not rely on an underlying Network Routing protocol. It is implemented directly on top of the link layer. VRR provides both raditional point-to-point Network Routing and DHT Routing to the node responsible for a hash table key.VRR can be used with any link layer technology but this paper describes a design and several implementations of VRR that are tuned for wireless Networks. We evaluate the performance of VRR using simulations and measurements from a sensor Network and an 802.11a testbed. The experimental results show that VRR provides robust performance across a wide range of environments and workloads. It performs comparably to, or better than, the best wireless Routing protocol in each experiment. VRR performs well because of its unique features: it does not require Network flooding or trans-lation between fixed identifiers and location-dependent addresses.
