Design and Implementation of Mobile Computing Simulator

Abstract

The Rapid progress in communications and wireless technology, especially in mobile computing, resulted in wide area of development in design, control and simulation of protocols that manage the wireless network. In this paper, a software simulator package has been designed, implemented and analyzed to simulate Internet Mobile Host Protocol (IMHP), Multicast Routing Protocol (MRP) and Handoff operation, which feature both route optimization and integrated authentication of all management packets. The simulator coverage area includes three extendable subnets (LANs) with ten mobile hosts moving either randomly or manually over the network. The moving hosts have the ability of entering or leaving the network at any time. The designed simulator simulates all the predicted events that practically associated with mobile computing operation. In addition, the simulator stands for other events such as the rebooting or crashing in the network elements. The simulated protocols are tested in terms of the speed of implementation, which computed throughout the designed simulator operation for both IMHP and MRP protocols. Also the effect of Handoff process on the mobile protocols implementation has been tested. The obtained results showed that the short cut route exhibits the fastest speed of implementation. Visual Basic programming language has been used in the design of this simulator.
