Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging. As a result, routing protocols play an important role in managing the formation, configuration, and maintenance of the topology of the network. A lot of routing protocols have been proposed as well as compared in the literature. However, most of the work done on the performance evaluation of routing protocols is done using the Constant Bit Rate traffic. This paper involves the evaluation of MANETs routing protocols such as Ad hoc on Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Temporary Ordered Routing Algorithm (TORA), and Optimized Link State Routing (OLSR) using Http Image Browsing traffic. The performance metrics used for the evaluation of these routing protocols are delay and throughput as a function of the load. The overall results show that the proactive routing protocol (AODV) performs better in terms of delay and throughput . پرونده مقاله

Today persons sitting at either end of the world can speak with each other with the aid of wireless technology. Mobile ad hoc Network (MANET) is a type of wireless ad hoc network which is a collection of mobile devices that creates a random topology for communication. The advantage of MANET is that it does not require any central controller or base station. MANET is only a network in which devices work as a host as well as a router. Routing in ad hoc networks has become a popular research topic. There are several routing protocols developed for ad hoc networks. In MANET, it is a very difficult task to predict the performance of routing protocol under varying network conditions and scenarios. This review paper is discussing the three approaches of routing protocols such as Reactive (On demand), Proactive (table driven) and Hybrid routing protocols with their advantages and disadvantages. پرونده مقاله
