Design and Simulation of Wireless Sensor Network

Question: Discuss about the Essay for Design and Simulation of Wireless Sensor Network? Answer: Network Design (NA) Proposed network infrastructure Sun Net organization want to implement a new network infrastructure for their company. Sun net organization have four different working unit which needs to connect to a single network. The four unit which are needs to be attached to this proposed system is main office, media center, design center, manufacturing center. As per Sun net directors requirement, there are some specific tuning needed for better scalability of the network. Figure 1: Sun net network infrastructure (Source: created by author) Above displayed network infrastructure diagram represent the overall functionality of the proposed system. This proposed network has four different segments for its four different working unit. The main office is linked up with a high-value multi-layer switch to provide a high-bandwidth video link in-between main office and media center. This multi-layered switch is capable of managing two different links concurrently. Where one is utilized for the high-bandwidth video link and another one is for providing a slow speed file transfer link. Apart from this particular connection, the other units are also connected to the central office network. The other network segments are design and manufacturing unit which are implemented a switch for providing a valid link to the entire network. The main office is network is concurrently processed by another three network, so main office network segments need to be more accurate and robust. For providing better solution a buffered server is implemented on the main office network. When the main office network is congested by network traffic overheating then, this buffered server cached some data packet to maintain the network stability. Cost estimation According to this network infrastructure the proposed network cost is divided into two category where one for the network components costing and another one for end devices. Components Price Router $10000 Servers $150000 Utilities (cable, end devices) $200000 Simulation of sun Net network (Only test report Applicable as per bookings) Overall sun net network connection in ns2 Figure 2: Sun net network infrastructure overall network design (Source: created by author) This above described represent the overall Sun net network working functionality. Where 0-3 represents four network segments and 5, 6 represents connection entities. For connecting four network segments there, only one network entities will be sufficient, but sun net implements a buffered server for its high-speed cache functionality. So another node (node 4) will cache oversized traffic and stable the network capability. Figure 3: Sun net network infrastructure overall network design (contd...) (Source: created by author) In this above picture displayed how the overweight traffic is cached and managed by the server (node 4) for creating a valid network connection between node 5 and other (node 0, node 1, node 2, node 3). Fast and slow speed network connection The picture which is demonstrated below is to visualize the slow speed and high network connection utilization procedure. Where a specialized network infrastructure is set-upped. Node 0 represent the main office; node 1 represents media center, node 2 represents design center, and node 3 represents manufacturing center. According to Sun net director notes, a high-speed link is created among main office and media center for providing a high quality video link. A low quality link is established between the main office and design center for providing a low quality link. A high-speed link between the main office and media center. And a high sped connection among manufacturing and design section. Figure 4: Sun net network TCP speed separation (Source: created by author) Network congestion- Proposed Sun net network infrastructure needed to be well equipped to protect networks data transaction and data integrity. So for the data packet, validation and error checking sun net implemented a congestion network tracker which can simulate the network function ability toward error checking and error detection. The displayed picture which is attached bellow represents the network's packet loss due to dense network traffic.
