1. PERFORMANCE ANALYSIS BY SIMULATION OF A WIRELESS SYSTEM ASSOCIATED WITH UWB
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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

2. Implementation and performance analysis of star-based mesh network
University essay from JTH, Data- och elektroteknik; Tekniska HögskolanAbstract : 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

3. Performance Analysis and Optimization of One-hop Network Coding in Multi-hop Wireless Networks
University essay from Institutionen för informationsteknologiAbstract : 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.

4. Performance Analysis of WLAN MAC Algorithms
University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapAbstract : 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

5. Simultaneous Mobility Management in Seamless Handover by using mobile SCTP (mSCTP)
University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikationAbstract : 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
