Soorty, B; Sarkar, NI (IEEE, 2013)Implementing IPv6 in modern client/server operating systems (OS) will have drawbacks of lower throughput as a result of its larger address space. In this paper we quantify the performance degradation of IPv6 for TCP when ... -
A review of New Zealand Telecommunications: Legislation, Regulations, and Recommendations
Gul, S; Sarkar, NI; Gutierrez, J (Telecommunications Association Inc., 2016)The telecommunications industry is growing and changing at a very high pace. To keep up with this high pace and fast changing technologies countries need strong legislation and an efficient regulatory system to promote ... -
A simple distributed channel allocation algorithm for D2D communication pairs
Zhao, H; Ding, K; Sarkar, NI; Wei, J; Xiong, J (IEEE, 2018)Device-to-device (D2D) communication is a promising technology due to its advantages of high spectrum efficiency, low energy consumption, and enhanced system capacity. In D2D communications, the channel allocation plays a ... -
Strategies and guidelines for improving wireless local area network performance
Sarkar, NI; Sarkar, NI (InterNetWorks Research Lab, Universiti Utara Malaysia, 2012)There has been a tremendous growth in the deployment of IEEE 802.11 (a/b/g/n) wireless local area networks (WLANs) in recent years. This growth is due to the flexibility, low cost, simplicity, and user mobility offered by ... -
Teaching computer hardware and organization using PIC-based projects
Sarkar, NI; Craig, TM (Manchester University Press, 2006)Until recently, it has been difficult to motivate students to learn about computer hardware because students find the subject rather dry and theoretical. We have prepared a series of interesting projects that give students ... -
Teaching computer networking fundamentals using practical laboratory exercises
