Nt1310 Unit 5 Simulation Report
VI. SIMULATION EXPERIMENTS AND RESULTS In this section we explain our simulation framework for assessing the performance of our proposed QoS-based CR-WMSNs routing protocol. Afterwards we describe different simulation results representing the efficiency of the proposed QoS-based MAC protocol. A. Simulation Framework Our CR-WMSNs simulator has been developed based on OPNET [31]. Before discussing to the simulation results, we would like to have a glimpse of the assumptions and major parameters: 1) OPNET simulator[31] is used to generate 100 sensor nodes for a CR-WMSNs. Initially, the connectivity of the CR-WMSNs is kept as 0.7. The capacity of the network links is assumed to be Poisson distribution with mean 100 kbps. Every sensor is assumed to …show more content…
The video streaming traffic is considered to have 176 × 144 pixel resolution and an average Exponential inter-arrival with 10 frames/sec as specified with H.264 [32]. The non-real-time (NRT) and Best Effort (BE) data traffic are assumed to be long range Pareto distribution with heavy tails. The total size of files for NRT and BE data traffic are taken same as the overall size for video traffic. 3) The classification of traffic is performed based on the ToS field of IP packets. γ is kept proportional to the IP-ToS. The up scaling factor γup and down scaling factor γdown are considered as follows: (a) γup = 20 and γdown = 20 for video streaming (b) γup = 20p2 and γdown = 10p2 for NRT traffic and (c) γup = 40 and γdown = 10 for BE traffic. The active time for video streaming traffic and NRT traffic are taken as 4 and 2 times of the active time for BE traffic. 4) In our simulation CWmin and CWmax are taken to be 64 and 128 for BE traffic respectively, which corresponds to Prlower f = 0.05 and Prupper f = 0.40. We have set the corresponding values for the video streaming traffic to be 25% of the BE

There was a heavy downpour of rain and the driver of Vehicle 1 did not see Pedestrian 1 crossing Fletcher Avenue. Pedestrian 1 was walking southbound across Fletcher Avenue, in or near the marked crosswalk, on the west side of 22nd Street. Pedestrian 1 was walking against the “Do Not Walk” signal, for pedestrian traffic.

602 Words | 3 PagesJason, I will address each of your points below: 1-4: I am positive the system and scenes are 100% functional. I have tested several times, most recently with the Lutron programmer about 2 weeks ago, and everything worked. Last night, I tested the scenes again and confirmed the lighting worked by looking at the front door camera. Regardless, I am headed over shortly to confirm, again. My guess is Ms. Mathews is not fully aware of the functionality of the system.

452 Words | 2 PagesThe main difference of a WiFi to Token ring and Ethernet networks is that it does not require a physical media from the source to the receiver to create a network and establish a connection, although WiFi would not compete with speeds of data transfer of an Ethernet. A WiFi connection is made by using a wireless adapter(that converts digital information to radio waves and back with antenna) to create a hotspots that allow access to internet service. WiFi technology is using 802.11 networking standards (802.11a, 802.11b, 802.11n etc. ) that will depend on needs for the user. In wireless networks there are two logical typologies that are use, a star and point-to-point (devices connect directly to each other and do not need access point device to communicate), in general WiFi speed is on average 20Mbps, however it can vary on many factor like distance between users and source or media radio waves has to travel through on the way to the user and
Nt1310 Unit 4 Qos Research Paper
385 Words | 2 Pages4 QoS Based Protocols QoS based protocols ensure sensor nodes balance between energy consumption and pre-determined QoS metrics like delay, energy, reliability and bandwidth, before delivering data to sink node. Sensor nodes have low processing capability, low memory power and limited transmission energy in addition to energy constraints. Hence the constraints impose an important requirement on wireless sensor network QoS support mechanisms including simplicity. Traffic flows from many sensor nodes to a small subset of sink nodes in most WSN applications. QoS mechanisms must be made for unbalanced QoS-constrained traffic.

Regarding your request, we - GI_SSC_OM_S1 and GI_SSC_MFGPTS_S1 squads - only will be able to answer the Security and Risk questionnaire after we access the environment of our clients, that only will occur when Chris Maurer validates the data we sent to him from application owners and he informs us how we must to procede to start the access procedures without violate the export regulations rules from IBM. As we only receive part of the list that we sent to application owners (AO) yet, we have two situations right now: some data still under verification by AO and others under validation of Chris, as the graph bellow: Our PO and SLL are aware of this situation.
Nt1330 Unit 1 Review Paper
572 Words | 3 PagesNetwork monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system called Marple was created by researchers at MIT, Cisco Systems, and Barefoot Networks(Hardesty). Marple involves a programming language the allows network operators to specify a wide range of network-monitoring tasks and a small set of simple circuit elements that can execute any function specified in the language.

If you are willing to root the HP SlateBook device, you can head over to the Google Play Store and install apps such as the Link2SD app. The Link2SD app doesn 't exactly give your device more space. However, it does create an easy way for people to transfer apps over to the SD card to free up more internal memory space. Many people have no idea how to use their SD cards and this Lin2SD app helps those people.

Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment.

Towards the end it will work out where it need to go and which devices will take the data. Also devices and software such as for interface card for the device driver. This is allowing the data to handle incoming packets from various locations and it select the last place it travels to. Error handling and diagnostics is when a device is allowed to access a network layer locally.
