[Other] PKT DL : 0: * Network Coding Network Simulator * * 06/10/05 - Aaron Drew * * This simulator is designed to test out the performance of a variety of network coding approaches. * * It simulates networks with dynamic topologies, reading from NS2 compatible node mobility files. * I assume that: * - wireless nodes are effected by a simple exponentially distributed noise floor. * - latency = distance x speed of light + fixed processing time + random jitter. * * These assumptions can be easily changed in the code below. * * The simulator is a simple discrete event-based simulator like NS2, GloMoSim and others but designed specifically to support * my network coding experiments. It has callbacks for 'transmit buffer empty' and may eventually support 'in air' collisions * of packets and multiple radio channels. I didn't want to have to build upon the unnecessary MAC layers that exist in the * other simulators. * * The network coding module in rlnc.h implements basic block encoding and decoding as well as block generation by intermediate * nodes that have received partial data.

[SCM] mobility DL : 0: Wireless range extenders or wireless repeaters can extend the range of an existing wireless network. Range extenders can be strategically placed to elongate a signal area or allow for the signal area to reach around barriers such as those created in L-shaped corridors. Wireless devices connected through repeaters will suffer from an increased latency for each hop. Additionally, a wireless device connected to any of the repeaters in the chain will have a throughput that is limited by the weakest link between the two nodes in the chain from which the connection originates to where the connection ends

[Program doc] s01-3 DL : 0: Advances of diverse wireless access technologies are defining the trends of future wireless networks, named Next Generation Wireless Networks (NGWN), where several access technologies will coexist and devices will be equipped with different network interfaces, in order to take advantage of each access technology. In NGWN communication maintenance is a concept willing to reach. Therefore, strategies to tackle mobility and multihoming issues are required. In this paper we propose an extension of HIP in order to cover challenges that end to end mobility presents in NGWN. Our approach consists on sending access technology related information before handover execution occurs, in order to optimize handover process. Moreover, the extension tackles QoS issues by sending application requirements as well as restrictions or improvements affecting its performance in the new access technology.

[Internet-Network] ResistantCrossLayerProtocoMAnet.pdf DL : 0: This dissertation contributes a jam-resistant communications protocol for use in mobile ad-hoc network (MANET). Specic focus is given to the network layer rout- g of packets within a MANET. A MANET is a self-organizing multi-hop wireless twork that is comprised of many mobile hosts communicating wirelessly. As a result their mobility and dependence on wireless communications, network layer routing especially prone to errors. An algorithm has been developed using the concept concurrent codes to allow for jam-resistant wireless communications without a pre- shared secret. The algorithm allows for the recovery of messages even in the presence of signicant noise. Experimental results show that a cross-layer protocol designed to take advantage of this property allows for more eective communications in noisy environments such as disaster sites where current network protocols experience signif- icant packet loss rates. Ultimately, this research presents a communications protocol

[Program doc] Energy-Efficient-Routing-Protocol-for-Wireless.zi DL : 0: The proposed routing protocol for Wireless Sensor Network is hierarchical and cluster based. The protocol supports mobility in the Sensor Nodes as well as in the Sink. The entire protocol is described in terms of two phases namely Setup Phase and Data Forwarding Phase. After deployment of the Sensor Nodes entire sensor field in divided into some logical clusters and each cluster contains Sensor Nodes with different roles such as Gateway Node, Cluster Head Node and Ordinary Sensor Node. Majority of the computation intensive tasks are carried out in the Sink. Simulation results show the energy efficiency of the proposed protocol. The performance of the proposed protocol has been compared with that of CBR mobile WSN and results show better performance of the proposed protocol. Future scope of the work is outlined.

[Program doc] Deploying-Wireless-Sensor-Networks DL : 0: In this paper, we study the issue of sensor network deployment using limited mobility sensors. By limited mobility, we mean that the maximum distance that sensors are capable of moving to is limited. Given an initial deployment of limited mobility sensors in a field clustered into multiple regions, our deployment problem is to determine a movement plan for the sensors to minimize the variance in number of sensors among the regions and simultaneously minimize the sensor movements. Our methodology to solve this problem is to transfer the nonlinear variance/movement minimization problem into a linear optimization problem through appropriate weight assignments to regions. In this methodology, the regions are assigned weights corresponding to the number of sensors needed.
