  1. 1. PERFORMANCE ANALYSIS BY SIMULATION OF A WIRELESS SYSTEM ASSOCIATED WITH UWB

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Tarek Tabchi; Khadim Hussain; Murtaza Jamal; [2013]
    Keywords : Ad-hoc network; AODV; DSDV; DSR; NOAH; UWB;

    Abstract : Ultra Wideband transmission technique is supposed to be a promising candidate for fixed and mobile ad-hoc networks in short range scenarios. Ad-hoc networks are characterized by a lake of infrastructure, thus routing protocols are needed to establish connections between nodes. READ MORE

  3. 2. Media Access Control for Wireless Sensor and Actuator Networks

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Muaz Un Nabi; [2012]
    Keywords : NS-2; WSN; IWLAN; DCF; PCF;

    Abstract : In a wireless network, the medium is a shared resource. The nodes in the network negotiate access of the shared resource using the Medium Access Control (MAC) protocol. The design of a MAC protocol for a sensor node is not the same as that for a wireless transceiver. READ MORE

  4. 3. Implementation and performance analysis of star-based mesh network

    University essay from JTH, Data- och elektroteknik; Tekniska Högskolan

    Author : Muhammad Haq; [2011]
    Keywords : WSN; PAN-coordinator; Full-function device; Reduced-function device; Mesh topology; Beacon Network simulator; NS-2; Shadowing model;

    Abstract : The goal of the thesis is to design the star-based mesh topology by introducing multiple pan-coordinators (hub/switches) under a multipath-fading environment and to improve the data transaction rate of a network which usually gets worst when there is a single pan-coordinator for synchronization of devices in conventional mesh topology; also reduce the hop-count as least as possible. Most of the work has been done on NS-2 network simulator; therefore the research model which has been used here is a simulation model. READ MORE

  5. 4. Performance Analysis and Optimization of One-hop Network Coding in Multi-hop Wireless Networks

    University essay from Institutionen för informationsteknologi

    Author : Lu Liu; [2011]
    Keywords : ;

    Abstract : In this paper, we analyze the performance of one-hop network coding in multi-hop networks and optimize it by two solutions. One is evaluating cost-delay tradeoff of opportunistic network coding in a two-way relay network with asymmetric arrival rates, we first formulate the variance of the queue into a Markov chain and derive the transition probability and the stable distribution.

  6. 5. Self-Organized TDMA protocol for Tactical Data Links

    University essay from Kommunikationssystem

    Author : Wichai Pawgasame; Wuttisak Sa-Ad; [2011]
    Keywords : Self-organized TDMA; Tactical Data Links;

    Abstract : A Tactical Data Link (TDL) system has been deployed in many military missions as a winning strategy. The performance of a TDL system is governed by the MAC protocol. The MAC protocol that is able to provide more flexibility and high quality of services is more desirable. READ MORE
