摘要：The demand for high data-rate multimedia wireless communications has been growing rapidly. As standards are addressing higher capacity wireless links to meet increasing demands, device power consu mption is also increasing. Although silicon technology is progressing exponentially, doubling about every two years, processor power consumption is also increasing by 150% every two years. In contrast, the improvement in battery technology is much slower, increasing a modest 10% every two years, leading to an exponentially increasing gap between the demand for energy and the battery capacity offered. Furthermore, the shrinking device sizes are also imposing an ergonomic limit on the battery capacity available. A wireless network consists of a large number of small sensor nodes with sensing, data processing, and communication capabilities, which are deployed in a region of interest and collaborate to accomplish a common task, a sensor network has many unique characteristics, such as denser node deployment, higher unreliability of sensor nodes, asymmetric data transmission, and severe power, computation, and memory constraints, which present many new challenges for the development and eventual application of wireless sensor networks. In particular, sensor nodes are usually battery-powered and should operate without attendance for a relatively long period of time. In most cases, it is very difficult and even impossible to change or recharge batteries for these sensor nodes. Thus, energy-saving routing protocol in wireless networks is necessary for increasing the network lifetime. In this paper we present a comparative study of different routing algorithms and analysis of same is presented in the paper. Different routing protocols have been proposed to improve the performance. All routing protocols have different behavior than others for improving and maintaining the routing performance. Routing protocols determines the route, which is required .The determination of route is done by the routing algorithm. The routing protocol first sends the packet to the nearest node and then that node sends the packet to next node. In this paper survey we find that what effects are given by different routing protocols (AODV, BATMAN, DSR, Proactive, Reactive and OLSR) in MANET for number of nodes, packet length and mobility. To give the answer of above question we check out the performance of these routing protocols. This electronic document is a "live" template.
