Performance ApriLoC should be able to operate 24/7 without any disruptions. The system should also have enough secondary memory to store all user information and device information and log information especially as the system grow. ApriLoC should also perform various tasks efficiently such us log in, changing passwords etc. Additionally, the system should ensure top notch security in the organization using the product.

We tested the system interactiveness by checking if anyone can be a floor chair if the chat and whiteboard are still functioning. Obviously, it works because the data was synchronized. Also, it is incomparable with H.323 because it did not implement this feature. We analyzed the components that were synchronized.

b. Protein intake and DRI-RDA From my longhand calculation sheet, my protein RDA goal based on 0.8 g protein/kg body weight was 43.9 g/day, which is slightly lower than my 3-day average intake which was 45.08 g. According to these values, I am not concerned about my protein intake value because protein is not a major source of energy and it does not store in the body. As a result, for me, maintaining the similar amount of protein intake is a better choice. If the protein are over consumed, it might leads to the deficiency of nutrient-dense foods intake and increase potential risks of kidney disease and colon cancer (Hammond, 2016b). On the other hand, if we consume too less protein, the risks of malnutrition and life-threatened diseases such

The hospital will establish policies and standards that protect patient privacy of the health care information. These policies should determine levels of access to the EHR. The Cerner® system will provide many layers of protection. A major piece of maintaining patient privacy is managing access to the EHR. This is accomplished through password management. The system will require case sensitive passwords with mandated password change every 90 days. There is employee badge swipe access that automatically enters the user log in ID but requires the password be entered. If a user has not accessed the system in a designated time period, which will be determined by the hospital (typically 90 days) then the system will automatically drop the

Temperature & Humidity Control – The servers currently sit underneath large air conditioning vents. Condensation can form inside these vents and cause equipment shortages. The temperature of the room in which the servers sit is currently suitable for electronics. If cooling is an issue at other times of the year, then the following suggestions will help to keep the equipment cooler:

Figure 8.3(a) demonstrates a portion of a wireless ad hoc network where a source node S has a data packet to be sent to a destination node that is

The First World Bank Savings and Loan network infrastructure update will be Linux based. The bank will utilize a custom kernel designed with the input of a Linux Security consultant. This proprietary kernel is adaptable, scalable and modular to readily handle the bank’s network. This kernel was collaboratively developed by the bank’s Security and IT directors with a consulting firm that specializes in Linux network security.

Answer 3) Though aggregations, CIDR scheme can decrease forwarding tables. The practice of aggregation can still be inhibited by few components. For example a network 208.12.21/24 needs to use the IP address allocated in the same network and the same IP prefix to be used when it needs to modify its

| 4 | Given a network topology of three or more routers with bandwidth designations, compare the metrics used during the route selection process and the resulting routing tables generated by the DUAL and SPF algorithms.

In this example, we have three routers A, B and C. C’s E0 is directly connected to 192.168.3.0. And C’s routing table is (192.168.3.0; 0; E0) which shows that 192.168.3.0 is 0 hop away. RIP (Routing Information Protocol), running on C, tells B that 192.168.3.0 is reachable through C

(b) Redirection with modified hop count: This type of attack is targeted against the AODV protocol in which a malicious node can increase the chances that they are included on a newly created route by resetting the hop count field of a RREQ packet to zero. [17]

3.7.1 Reactive/On Demand Routing Protocols Reactive routing protocols were designed to reduce the overheads by maintaining information for active routes at each node [8]. This means that each node determined and maintained routes only, when it requires sending data to a particular destination. It using two main mechanisms for route

Several energy-aware routing protocols have been proposed in literature for heterogeneous WSNs. In \cite{Georgios2004}, the authors proposed SEP, a Stable Election Protocol, that improves homogenous LEACH protocol \cite{Heinzelman2000} by considering two levels of heterogeneity: normal nodes and advanced nodes, where the later are equipped with an extra amount of energy. The cluster head is selected based on a weighted probability according to the node initial energy in such a way that the nodes having a higher initial energy become cluster heads more times than the other nodes. The election probabilities for the normal and advanced nodes are given as follows:

However, there are many limitations with DTN’s. For example, asynchronous connectivity among the devices makes it necessary for the sensors to forward messages via relays or alternate paths to ensure delivery, or they need to store and forward the packets opportunistically until they reach the destination. This very often results in huge transmission delay, high overhead or low delivery rate. Taking into consideration the constraints on remote sensing devices, such as battery power, storage capacity, processing power, and communication bandwidth can affect the network performance and successful message delivery rate. Hence there is a need for routing protocols of DTNs be enabled to adapt according to network variations and effectively use the existing resources. Recent studies show that the most of existing protocols for DTNs look very similar in concepts; however, their performance significantly differs from each other. Epidemic [5] is a robust algorithm as it floods packets to all devices in the network. Spray and Wait [6], a modified version of Epidemic, controls flooding of messages forwarded. It simply limits the amount of messages that can be forwarded International Journal of Wireless & Mobile Networks (IJWMN) Vol. 7, No. 3, June 2015 56. The

The UPR makes routing decisions locally based on the destination address in the packet header and availability of outgoing channels. If
