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. Performance Analysis of WLAN MAC Algorithms

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Amer Khoulani; Ramaz Samhan; [2010]
   Keywords : WLAN; MAC; DCF; EDCF; DIDD;

   Abstract : Lately, researchers were trying to put a lot of efforts to enhance the performance of Wireless LANs. IEEE 802.11 algorithm, DCF, was an interesting subject for studies. Most studies were concentrating on avoiding collisions, packets loss, decreasing transmission delay and enhancing the overall performance of the network. READ MORE
