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. 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.

   Abstract : Network coding is a very promising technology to efficiently utilize resources of both wired and wireless networks, and has received much attention from both academia and industry recently. Since wireless channel is inherently broadcast and suitable for application of network coding. READ MORE

5. 4. 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

6. 5. Simultaneous Mobility Management in Seamless Handover by using mobile SCTP (mSCTP)

   University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

   Author : Md. Ibrahim Chowdhury and Mohamad Iqbal; [2010]
   Keywords : mSCTP; Simultaneous Mobility; Location Management; Handover Latency; Location Server LS ; step_length; NS-2.;

   Abstract : This thesis proposes a new solution approach for the simultaneous mobility issues in seamless handover for next generation wireless networks and envisages the vision of seamless roaming in IP mobility. Simultaneous mobility problem occurs while both of the communicating mobile nodes (MNs) change their location simultaneously and consequently losing their corresponding binding updates. READ MORE
