Abstract: Many routing protocol methods have been proposed in Mobile Ad-Hoc Network but still the challenges are to improve the routing performance. In small or medium ad hoc networks flat protocols can be used but in case of large networks more complicated routing protocols are needed to be used in order to be suitable with them. Since the Ad-hoc networks have many constrains in bandwidth and battery life so the routing protocol which is used must be done its work correctly without using much resources of network by its overhead traffic. This paper, focus on investigation the performance analysis of four important routing protocols in mobile Ad hoc networks such as AODV (Ad- Hoc On-Demand Distance Vector), DSR (Dynamic Source Routing Protocol), DSDV (Destination Sequenced Distance-Vector), and OLSR (Optimized Link State Routing Protocol). The analysis of performance is made on QoS parameters such as the basis packet delivery ratio, throughput, and end-to-end delay, the simulator used is NS-2.

Abstract: Productivity gap on SoC design is a challenge to address in design method research area. Main research topics in this area address this problem using many schemes and methods. Software for automation in a system design and implementation is one solution to address design time efficiency. The second one is parallelism concept in hardware/software co-design. This approach addresses both design time efficiency and flexibility. This paper proposes an automated SoC design software with respect to parallelism and automation concept. Hardware/software co-design is an implementation of parallelism concept. In the traditional design, the main concept is hardware design and then software design. In this paper we did both design in parallel mode. The result showed that the proposed method can reduce much more time than before.
