Worldwide interoperability for micro wave access (WiMAX) is a wireless network that have attracted the attention of researchers on the area of power savings, because of the increase in multimedia applications that consumes more battery power of Mobile stations (MS). MS experience an increase in their daily operations with limited power enforced on the MS; hence the need to optimally increase efficiency; due to the excessive power consumption experienced by MS; which significantly affects the performance of MS since, MS are battery powered with a super impose life, improving the life time of MS is imperative. Thus, this has led to numerous research works on energy-savings. Hence, we have presented a survey on the recent and past energy-saving schemes, aimed at understanding some of the most relevant sources of inefficiency in energy savings and how some of these challenges are solved by the existing solutions. We further presented a comparative analysis on these schemes with the aim of identifying current challenges that are yet to be addressed by the research community as well as presents future directions towards efficient energy savings in WiMAX networks.

Cybercrimes in various forms are on the raise daily; these crimes pose a potential threat to our moral society as well as economy and nation building at large. They are namely: social engineering, malvertising, ransom ware, Spamming, Botnets, fake bank alert messages (SMS) /unsolicited SMS requesting you to provide bank details as Bank Verification Number (BVN), fraud, identity theft, piracy, pornography, hacking, fraudulent e-mail related SMS, forgery such as fake documents as Certificate etc. Thus, Cybercrime is gradually becoming a threat to our moral society at large. Hence, the increase number of cybercrime rate is an open field of ongoing research studies. Therefore, we have proposed a new approach that emphases on the prominent cybercrimes carried out around the world, and presents a precise study in Nigeria within some secondary school students. The study revealed a new approach to fighting Cybercrimes in order to combat cybercriminals. Keywords: Cybercrime, Botnets, Malvertising, Ransom ware, Pornography
