    • Cognitive radio wireless networks 

      Joyantee, Tasnia Jahed; Iqbal, Niaz; Das, Ipshita (BRAC University, 2011-04)
      Standards groups and regulatory bodies around the world are increasingly seeking new ways of using, allowing access to, or allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur ...

      Standards groups and regulatory bodies around the world are increasingly seeking new ways of using and allowing access to allocating spectrum. In most parts of the world, cellular network bands are overloaded, but amateur ...

    • Performance comparison of medium access control schemes for IEEE 802.11 

      Kabir, Amran B M Zohrul; Alam, Mahjabeen A.; Ahmed, Lubna; Sabah, Sanjida Hossain; Ferdous, Hasan Shahid (© 2012 Institute of Electrical and Electronics Engineers Inc., 2012)
      The distributed coordination function (DCF) of the IEEE 802.11 standard based medium access control has drawn significant interest from the researchers in the past decade. Many proposals of its performance analysis and ...

    • Performance comparison of medium access control schemes for IEEE 802.11 

      Ahmed, Lubna; Alam, Mahjabeen; Kabir, Amran (BRAC University, 2012-04)
      IEEE 802.11 specifies a set of protocols for a wireless LAN defined by IEEE which covers the physical and data link layer. Nowadays, IEEE 802.11 based WLAN has a widespread and ubiquitous use in providing wireless connectivity ...

    • A study on the challenges and importance of vehicular network in the context of Bangladesh 

      Naz, Farah; Chowdhury, Tanzina Akter; Sabah, Sanjida Hossain; Ferdous, Hasan Shahid (© 2011 Institute of Electrical and Electronics Engineers Inc., 2011)
      The emergence of vehicular ad-hoc network (VANET) has provided the vital answer to vehicular communications. VANET can be either infrastructure based or simply lacking any. In our paper, we have dealt with an exemplary ...

    • Survey on the clustering schemes of mobile ad-hoc Wireless Sensor Network (WSN) 

      Ahmed, Mushrif; Sarker, Rakesh (BRAC University, 2012-09-04)
      This report aims to do a complete study on the different clustering algorithms of an ad-hoc wireless sensor network and compare them. In this paper we have understood, what are the basics of the 802.11 protocol, what is ...
