Network performance evaluation of 6to4 tunneling

Several types of IPv6 transition mechanisms have been developed to facilitate the migration of IPv4 to the new protocol, IPv6. Although all transition mechanisms have the same objective, the process necessitates compliance with their respective capabilities. This paper focuses on the evaluation of the transition mechanisms namely 6 to 4 tunneling in terms of data transmission. The assessment is based upon experimental work that is conducted on a controlled environment. User-to-user network performance software is used to obtain the throughput, round trip time and tunneling overhead for TCP and UDP transmission protocol. The performance of TCP and UDP through 6 to 4 tunnel is then compared over the native IPv4 and IPv6 environment. As a result, the findings prove the ease of TCP data transmission via the tunnel compared to both native networks. In contrast, the UDP implementations show the slight difference for them.

The Improved of BFOA for Ensuring the Sustainable Economic Dispatch

This paper introduced a new heuristic method the Improved to Bacterial Foraging Optimization Algorithm or IBFO to provide minimize objective functions in Secured Environmental Economic Dispatch (SEED) problems. An optimization problem may involve the highly non linear, non convex and non differentiable tends the solutions observed from a multiple local minima. The limitation faced by conventional methods are being trapped at any this local minima and prevent to reach the global minima. For that reason, this approach IBFO is tested under IEEE 118 bus system to obtain the minimum total cost function with less emission involved. Additionally, the proposed optimization approach is compared to original Bacterial Foraging Optimization Algorithm (BFO). As a result, all findings supported the novel IBFO as the competent and reliable technique.
