A) Broadcast domain is a domain in which (pcs, etc) can communicate via broadcasts, these are set up through switches, as routers block broadcasts.
B) Collusion domain: is a domain where info (packets) can collide with one another, as such only one device may communicate at a time.

2) Hubs deal with frames, switches do as well but they also utilize the mac addresses(so they direct what goes to what). Hubs share bandwidth with each available port as it copies each frame to each port (it broadcasts to each port even if its only requested by one). Switches don’t share bandwidth; each port is going to produce whatever it is rated for.
I would choose a switch, it would seem to be cost effective in time. Switches also designate which port is getting what info through mac addressing, making the network faster as each port is getting the full designated bandwidth (not shared like a hub). …show more content…

unlimited; thus, both symmetric and public/private key cannot be brutally decrypted within a reasonable time period. Therefore, encrypted data are secure to a certain degree when the key is not known to the attackers[7]. IV NETWORK MODELS We use two different network models, random way point model [7] and group mobility model [18]. With the random way point model as the default setting, we also compare the performance of ALERT in the group mobility model. Fig.3.GPSR Failure and Hand Rules 4.1 Parameters…

and including the last point showing if the speed was exceeded or not as shown in figure 6-5. A straight line is drawn between every 2 iteration points. After reaching the last entry a red marker is added indicating the ending of the path. Figure 6-7: Markers on the start and end points and coloured indicators for each data sent iteration This is obtained as when the GSM module sends the latitude, longitude and speed to the server side these information is updated into 2 tables one of them containing…

2. Multiple path identification i. Neighbour identification When the nodes are deployed in the network, they periodically broadcast the RREQ message to its neighbor nodes. The RREQ message includes the node ID and its location information. The RREQ messages, based on each node identifies itself and also maintains the neighbors list which contains the nodes ID and location of each neighbor node. When source node wants to transmit data packet to destination, a RREQ message is transmitted to destination…
