network. While passive attacks aremainly due to lack of cooperation with the purpose of saving energy selfishly.Nodes that perform active attacks with the aim of damaging other nodes by causingnetwork outage are considered as malicious while nodes that make passiveattacks with the aim of saving battery life for their own communications are consideredto be selfish. 4.1 WormholeAttacksWormhole attack is also called astunnelling attack. A tunnelling attack is where two or more nodes may collaborateto encapsulate and exchange messages between them along existing data routes. This exploitation gives the opportunity to a node or nodes to short-circuit thenormal flow of messages […]

H.323 is suggestion by the ITUTelecommunication Standardisation Sector (ITU-T) H.323 is an ITUTelecommunication Standardisation Sector (ITU-T) suggestion that outlinesprotocols for the distribution of Audio-Visual (A/V) communication sessions onall packet networks. It became a recognised standard in 1996 and H.323 alongwith its family of ITU-T recommendations provides multimedia communicationservices across a variety of networks. The standards are important because theyoutline how H.323 complaint components facilitate calls, share compressed A/Vand work in conjunction with non-H.323 endpoints. H. 323 is similar to SIP inthat both support VoIP and multimedia communications, however H.323 favours thetelecommunications-orientated approach to VoIP whereas SIP prefers theinternet-orientated approach. H.323 […]

 In recent years there is advancement in thesystem performance,technologies in wireless   communications. Wireless networks need  networks in which mobile nodes can communicateover paths. In MANETs, network survivability is must by which the batteryextent of the nodes get weak. Thus to continue the network period the routingprotocol is needed to raise the energy of the node. Multiple routing protocolssupport routes to flood the packets i. e., route appeal is directed by the sourceto achieve facts concerning the ways. MANETs can be classified into three generations:first, second and third generations. In 1970’s the ad hoc network firstgeneration are called Packet Radio Network […]

Adolescence is a time of vulnerable susceptibility,Social Media is defined as “the collective of online communications channels dedicated to community – based input, interaction, content sharing, and collaborations” and can be accessed from almost anywhere at anytime.  Smartphones have become the primary platform of mobile internet use for adolescents. In a  2015 Pew Research Center Study, 75% of all teens have smartphones and out of those 75%, 92% go online at least daily, including 24% of them that state that they are online “almost constantly.” The top three social network sites for teens are Facebook, Instagram, and Snapchat, where they […]

Social mediaSocial media is a computer-assisted expertise that enables the formation and dissemination of information, concepts, professional comforts and other forms of communication via groups and cybernetic systems. The diversity of currently available individual and integrated social media announces description competitions, although there are common structures.Common properties of social media entities:• Social Media is an interactive web presentation on Web 2.0• It includes user-created content, such as transcripts or comments, digital images or videos, as well as figures created across all virtual communications. • Users create service-specific sketches for the website or apps that are scheduled and maintained by their […]

Encryption     The main purpose of encryption is to protect the data on computers or transferred using the internet or computer networks. Encryption is one of the most secure ways to protect your data. It is vital having a secret key or a password to be able to decrypt it.  Example:  the hard drive in a laptop may be encrypted, which means that a password is required to access data.Call Back SecurityIt is a security feature that checks the dial-in user, it checks the password, then it ends the call.   Later the person will receive a call back to make […]

Bosch is an organization that have a healthy mix ofemployees from all across the world, hence cultural barrier is one of thecommon reason for communications breakdown. Communications breakdown is asignificant issue to be address because employees must be able to communicatewell to work together harmoniously and contribute to the organizational success.The company could encourage their employees to share aspects of his or herculture with everyone, so that employees could learn and appreciate otherculture. Alternatively, employees could write a feature article in Bosch connectabout a culture. As a result of the diverse workplace, language barrier canoccur as well. Some of the […]

Iwill critically evaluate as an analysis method for post-election violence alsochallenges that victims go through. My discussion does focus on methodologicalconcerns correlated beside the use regarding interviewswhile post-election exercise as a research. I willevaluate the literature concerning post-election tumult inside Kenya.Moreover, summarize ethical concerns concerning the use of interviews beforedrafting a summing-up.  Literature review.  The dynamics in Kenya politicsis heavily about attached along the ethnic lines. The series offierce outbursts in many regions are based on opposition strongholds. Followingthe declaration regarding 2007 ballot results, the onslaught lasted for closeto two months (Burchard, S.M 2008). This unrest involved disagreements betweentwo ethnic associations concerning two main presidential candidates. Then-President Mwai Kibaki from one Kikuyu tribe, and formerly prime […]

In recent time there is change inthe computer performance, technologies in mobile communications. Mobile networkswant ad hoc networks in which mobile nodes will connect over line. In MANETs,network safety is essential by that the battery extent of the nodes be notstrong. Thus to continue the network span the routing protocol is needed toincrement the intensity of the node. Multiple routing protocols stay paths toflood the packets i.e., route appeal is managed by the point of supply to achievereality in concerning the ways. MANETs will be classified into threegenerations: first, second and third generations. In 1970’s the ad hoc networkfirst generation […]
