2. PROBLEM STATEMENT
A Review on Security, Energy & Congestion based issues in multipath routing for Wireless Sensor Network. The Simplicity in Wireless Sensor Network with resource constrained nodes makes them extremely vulnerable to variety of attacks. In a Wireless sensor networks sensor nodes monitor the environment, detect events of interest, produce data and collaborate in forwarding the data towards to a sink, which could be a gateway, base station or storage node. Securing the Wireless Sensor Networks need to make the network support all security properties: confidentiality, integrity, authenticity and availability. A sensor network is often deployed in an unattended and hostile environment to perform the monitoring and data collection tasks. When it is deployed in such an environment, it lacks …show more content…
After compromising one or multiple sensor nodes, an adversary may launch various attacks to disrupt the in-network communication. Among these attacks, two common ones are dropping packets and modifying packets, i.e. compromised nodes drop or modify the packets that they are supposed to forward. We expect sensor networks to consist of hundreds or thousands of sensor nodes as in Figure1.

Each node represents a potential point of attack, making it impractical to monitor and protect each individual sensor from either physical or logical attack. The networks may be dispersed over a large area, further exposing them to attackers who capture and reprogram individual sensor nodes. Attackers can also obtain their own commodity sensor nodes and induce the network to accept them as legitimate nodes, or they can claim multiple identities for an altered node. Once in control of a few nodes inside the network, the adversary can then mount a variety of attacks. Packet dropping is nothing but a bad node drops all or some of the packets that are supposed to be forwarded. It may also drop the data generated by itself for some malicious purpose such as blaming

We have run the specified test cases and can confirm that all but two functional requirements have been fulfilled by the prototype. In the first case, due to the sensitive nature of calculating accurate speed readings of an oncoming vehicle, further testing is required on the prototype, as sensor values have been inconsistent. Secondly, while we are confident that we can simulate an emergency notification message, we have yet to implement this functionality. Necessary adjustments were needed to…

values, without any specification of how the values are to be represented or how the operations are to be implemented." (Eck, 2016). Also, the most common ADT used is related to LinkedList, Queues and Stacks, which we are already familiar with in this Unit. What I understand from ADT is that we can use this mechanism for implementing a program hiding unnecessary details of implementation and focus on the behavior and operations that the program must have, and doing this we can improve how the software…

Blue Screen While Playing Dark Souls: We recently met with an issue while running some programs on the computer. Every time after launching the game Dark Souls the computer would run a BSOD with the error 0x1709. Also, this would happen when the computer…

another factor that is quite important for an OS, as should a system be easily manipulated then users could find they’re targeted by cyber attacks which are becoming more and more prevalent as society becomes increasingly influenced by technology. (1. Lecture Notes, Slide 5) Windows 10 was initially rolled out in 2015, with more of an emphasis on personal devices other than PC’s than previous iterations of Windows. Although Microsoft were already a significant market leader, they saw that the market…

1. Describe what you did. This does not mean that you copy and paste from what you have posted or the assignments you have prepared. You need to describe what you did and how you did it. I have researched over the internet to create the flowchart. As I mentioned earlier that I always get help from instructor’s example. What I am facing now is time management. Not getting enough time to research more on the particular topic. I have to put some extra time at my job as one of the projects is going to…

Methodology For the study, this chapter served as a means of gathering pertinent data. The study sample, populations, sampling process, data collection methods, data collection procedures, and tools used, particularly surveys and data analysis, were all explained. To choose the method that would be used, details on the population sampling procedures used in the study were also given. The primary objective of this chapter is to understand which tools or methods to use. This study will determine the…

On the above date and time, I was conducting traffic enforcement at 7902 U.S. 19 (People Ready). While stationary in the driveway at the location, I observed a light blue motorcycle traveling northbound over the Pithlachascotee River Bridge. I visually estimated the motorcycle to be traveling 78 MPH in a posted 45 MPH zone. I utilized my agency-issued speed measurement device, a Truspeed LTI 20/20 laser (T5015405), to determine the speed of the motorcycle was 80 MPH in a posted 45 MPH zone. I activated…

Discussion Assignment 1 In the modern world of data-driven applications, database systems play a pivotal role in storing, organizing, and retrieving data efficiently. As applications become more complex and interconnected, the architecture of database systems evolves to accommodate the increasing demands for performance, scalability, security, and maintainability (Silberschatz et al., 2011). Two common architectures for structuring applications that use databases are the two-tier and three-tier…

Question one Alpha refers to where Type I error is which is similar to the significance level is made. For instance, setting the alpha at .05 will signal that researcher is unwilling to take any big risk. Such an action of setting the alpha at .05 makes it nearly impossible to reject the null hypothesis by means of hypothesis testing except when it is on the extreme. When alpha (α) =0.05 its means that P (type I error) = 0.05, therefore rejecting Ho reason being that Ho true is 0.05. In simple terms…

query/ reply process used in LMR. When a node moves the DAG, route was broken and route maintenance is to reestablish the route to the destination. Route erasure phase involves broadcasting a clear packet to entire network to remove invalid routes [1]. The TORA protocol is required to maintain unique ID of the node; reflection indicator bit; propagation ordering parameter; logical time of link…
