The routing protocol is able to improve the performance of the network as compared to the traditional 3G and WiFi offload. On this study, the concept Genetic Zone Routing Protocol (GZRP) will be combined with the VHO algortihm used at the multiple base stations in 3G-WiFi offload network. Based on the results of this simulation the proposed algorithm can improve troughput and reduce handover delay. In terms of handover time, there is a significant improvement when the combined algorithm is employed as compared to the VHO algorithm alone, which shows a decrease of 2.757 seconds for the average handover time from 3G to WiFi and 3.824 seconds for the average handover time from WiFi to 3G. Keywords -load balancing: mobile ad-hoc network; 3G -WiFi offload; AOMDV; VHOI.

<p>A stepper motor is an electro mechanical device that can convert electrical pulses to the axis of movement. The finding problem  in the movement of a stepper motor is  cannot respond to the clock signal directly because the motor windings require a clock (sequence) in the correct order. If the control signal given is not correct, the motor is not moving according to the specified precision. To answer these problems, it is necessary to move the stepper motor with a clock signal that works in real time. The research method is done by designing and testing the stepper motor movement in full stepp and half step with the direction of Clock Wise (CW) and Counter Clock Wise (CCW) movement. These are simulated by using FPGA Isim and implementation using a stepper motor. The results of several experiments have been carried out the stepper motor movement degree according to the input value entered,responding timely movement, and the direction of movement stepper motor.</p>
