Multicast routing in mobile networking - Essay Example MAODV is the best in communicating from the sender to the receiver nodes. Packet delivery ratio for MAODV and AODV This is the ratio between the packet of data that are actually delivered and those sent by the source.AODV been a multicast routing protocol it performs slightly better than MAODV in terms of packet delivery ratio. The ratio increase as the number of receivers decreases. These are very shocking a result since MAODV is designed to handle multiple receivers. Magld (2007) This is a ratio measured against the pause time. It also used in measuring mobility. The results are expected because this is the testing a mobile ad hoc network environment.MAODV is seen to deliver more packets as long as time is not increased .It works better than AODV and FDQA. AODV and FDQA vary slightly overtime but they are much lower in terms of success rather than MAODV. Magld (2007) FDQA is designed to deal with one QoS requirement delay .FDQA has high end-to-end delay over time. In comparison to MAODV and AODV, which has lower latency in short, term .FDQA algorithm, this is based on Fanos algorithm. The simulation I have conducted is testing the effect change in the node delay that has the success ratio. I have also tested the node delay effect on the average message overhead. The result shows the node delay positively affects both FDQA and A0DV success ratios and it has much of an effect on average message overheads for FDQA. MAODV and AODV are compared in relation to three parameters namely; Throughput, latency and packet delivery ratio.MAODV has performed slightly better but not in all of them. It has generally works better in a multicast ad hoc network environment than AODV does despite having same similarities. In comparing MAODV, AODV and FDQA I have found that MAODV has a higher performance that FDQA in relation to packet delivery ratio.FDQA algorithm has been designed to address

Police corruption - Assignment Example It is marked by simultaneous occurrence of mishandling of official capacity and mishandling of personal attainment. It is carried out by violation of state or federal laws or the constitutional rights of the individual. Corruption may also involve material benefit or a profit gained through abuse of public authority. Police corruption is a pervasive phenomenon, yet it is not bound by ranks. It is typified by such acts as bribery, extortion, receiving or selling stolen property and aiding or abetting or carrying out drug pedaling. Broadly, it may also include indulging in such acts as violence and brutality, fabrication or destruction of evidence, racism, or favoritism. Knapp Commission describe three basic kinds of corruption; bribery, shakedowns and mooching . Police may use subtle to extreme methods to indulge in corruption. However, no single reason can be ascribed to the existence of police corruption (Gainer and Miller, 2008). Wicershkam Commission was appointed by President Herbert Hoover in 1929. George W. Wicershkam headed the National Committee on Law Observation and Enforcement, which was popularly called the Wicershkam Commission. Wicershkam Commission was charged with investigating the causes of widespread criminal activity and finding causes of violations of national prohibition policy. It was the first of its kind national level enquiry into the causes of crime and law enforcement. The commission presented its report in 14 volumes in a study carried out from 1931 to 1932. The commission handed out a severe indictment of police thus confirming the presence of misconduct and corruption in its functioning. Apart from the use of violence and brutality it also pointed out the instances of bribery, corruption, coercion, fabrication of evidence and entrapment. Knapp Commission or the Commission to Investigate the Alleged Police Corruption was appointed under the chairmanship of Whitman
