    • The effects of MAC protocols on ad hoc on-demand distance vector (AODV) routing protocol 

      R. Badlishah, Ahmad; F., Hashim; Sabira, Khatun; B. M., Ali (Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
      Ad hoc networks play an important role in mobile radio networks due to its flexibility and low operation cost. Several of key research issues of ad hoc network are on the routing and MAC algorithms. But, only a few of ...

    • Improving BER using RD Code for spectral amplitude coding optical CDMA network 

      Fadhil, H.A; Syed Alwee Aljunid, Syed Junid; R. Badlishah, Ahmad (Institute of Electrical and Electronics Engineering (IEEE), 2009)
      A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties ...

    • Performance analysis of optical zero cross correlation in OCDMA system 

      Anuar, Mat Safar; Syed Alwee Aljunid, Syed Junid; R. Badlishah, Ahmad; Saad, N.M.; Andonovic, I. (Asian Network for Scientific Information, 2007)
      We propose a new code structure for Spectral-Amplitude Coding Optical Code Division Multiple Access (OCDMA) systems with zero cross-correlation and theoretically demonstrate the performance of this code by using a direct ...

    • Performance of random diagonal code for OCDMA systems using new spectral direct detection technique 

      Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid; R. Badlishah, Ahmad (Elsevier Inc, 2009-01-31)
      This paper studies the performance of random diagonal (RD) code for spectral-amplitude coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection technique. RD code is constructed using code segment ...
