    The project consists of multiple video streams connected with Sink over Wireless Sensor Networks. Two video sources are connected to coordinator (Sink) through two hops or more. each source send video data to sink which will play video stream back. video trace file should be generated using Evalvid tools which is used to evaluate video over wire/wireless networks. Simulation should calculate End-to-End delay, and Average packet loss. more details will be provided latter.

    I want to implement a wireless sensor network with xbee remote module connected to remote sensor by serial communication in API Frame Mode. I want to receive in my station, data from remote sensor connected to xbee module via rs232 in API Frame mode and in sleep mode to reduce power consumption.Is possible set sensor in sleep mode to reduce power consumption, sending pulse of 200 ms duration to sleep and wakeup the sensor device.

    Hi there,I have a subject which has 6 tutorials and their answers are included but I"m struggling with some questions especially the subnet masking and the routing. This subject is taken from the book "Tanenbaum, A. S., Wetherall, D. J. 2010, Computer Networks, 5, Pearson".I would need someone who is really good in this and help me out with understanding the way of solving the questions that I struggle in by including me full details of the answers which I have, and if you could teach me via skype it is more preferable and for sure I will still need written explanations of the answers or typed and word is better for me.Thank you.

    I need help to build an application for my final exam. The application will be able to monitor devices and equipment such as routers, computers, printers etc. over the network(LAN/WAN). I think is a good idea to work with snmp protocol. I want it to be developed in python and django. The app. should be able to:- find computers, printers and devices over the network (ICMP packets, NMAP etc.);- scan and report if the ports 161 and 162 UDP are opened;- gather information from OID"s (device name, CPU load, RAM state, etc.) and store them into database;- store information about cpu usage, network usage in Round Robin databases;- any new ideas are welcome.Because I"m a student the budget it"s very low. I just want to get help, not you to build the entire app by yourself. Thank in advance!Best regards, Moris

    The scope of this project is to connect X number of machines with a master , through an WiFi access pointA master CPU will send request to each machine on the network (a string of 5 bytes)It will start from first address x.x.x.1 to the last one x.x.x.254Each of the slave will reply with a string of 5 bytes.After the last address, 254, the master will start again from first address.As it is not know what machines are in the network, the master have to send request to the entire 254 range. The IP address is assigned manually at each machine.Your task is to take care of communicationWhen data to be sent out is ready , a bit will be set to let you know that a 5 bytes string has to be sent out.When data is received from WiFi controller, a bit should be high to let me know i have new data to read.The other way is to store the data to be sent on eeprom , and you will take it from there, and store new data received on eeprom also at receiving address.Also you should provide a way to monitor sent data and received data on a laptop which monitor traffic.The topology and suggested hardware are on the attached files.For language, i prefer MikoBasic from Mikroelectronika.

    A project involve simulation on scheduling algorithm for energy consumption in wireless sensor network (WSN).By taking turns (schedule), such as which sensors should be in an active state and which should be in a sleep state, the network’s efficiency is improved, and we get a substantial increase in the network’s lifetime.Project Requirement:•This project are based on journal (please refer attachment)•To be able to atleast re-produce the result on this paper on Energy Signal Scheduling (ESS) and make a little enhancement on it (please discuss payment depend on the enhancement of technique to be done).•Algorithm/technique use: sleep/wake scheduling algorithm, Gur game theory, ACK automata.•Simulation tool is NS2 simulator where ( tested 100 nodes randomly distributed. The ideal nodes propagation is assumed, with no signal loss, no interference, and no collisions.)•Should be able to run the simulation on ns2, able to produce the results, analyze the result and investigate the energy consumption/efficiency.•A small a written report of analayze results (graph(s), table(s), source codes, explanation).•Put in the report the complete source code of your simulation program(s). The source code must clearly state the command line(s) for running the program(s)•Plagiarism are not acceptableDue date:20 April 2014 (earlier are better)Budget:30 - 225 usd

    Video distribution over the Internet has already become a major application due to users’ growing demand of Video content and continuous growth of network technologies. Recently, as the rapid growth in the number of Video delivery systems, people ask for more and more video resources, which cause overload on network resources. Peer-to-Peer (P2P) network is an important component to implement such systems, how to quickly and efficiently deliver the video resources in P2P networks has become one of the most critical issues, at the same time, this is one of greatest concern to users. One major quality of video delivery metric is playout latency which can be considered as one of the key challenges that face many researchers nowadays. One major quality of video delivery metric is playout latency which can be considered as one of the key challenges that face many researchers nowadays. On the other hand, as cloud computing grows rapidly and more Internet users prefer to watch video or listen to audio online instead of downloading them to their local disk, it is critical and important to provide a cloud data storage and media delivering services continuously to deal with VoD systems. To address the above issues, this paper proposes a novel cloud framework for P2P VoD system.i"d like to purchase a p2p model using opnet modeler that simulates video on demand like youtube site. but i need to add some contributions such as pre-distributing the vidoes according to user intersets.
