Abstrakt: Ad hoc networks require efficient dynamic routing protocols to tackle the issues raised by their change-prone network topology and the fact that packets typically traverse multiple hops to reach their destinations. Ad hoc networks combine arbitrary mobile hosts with wireless communication capabilities, which come together into a temporary network formation consisting of self-contained, not centrally managed, resources. Nodes in an ad hoc network may be further apart than the range of the wireless devices used for communication; in such cases, intermediate nodes participating in the network can be used to transfer packets between the data source and sink. Two widespread routing protocols that handle such transfers are the dynamic source routing (DSR) and the ad hoc on-demand distance vector routing (AODV) protocols. In this work, we use simulation to compare the performances of these two protocols. Although the approaches taken by these protocols share a considerable number of common features, our simulation has shown that differences in performance figures exist, which may be attributed either to implementation issues or to interlayer operations. In our study, we have considered different network loads, the number of nodes within the network, and mobility parameters. [ABSTRACT FROM AUTHOR]
