Abstract: Mobile ad hoc Networks (MANETs) are temporary networks, that require relatively less time to be deployed and less resources to keep up and running. They can be implemented in disaster recovery sites, university campuses, military campaigns and so on. MANET nodes cooperate in an autonomous way by forwarding packets to each-other. Considering mobility of the nodes, the routes change dynamically so routing algorithms are very important for operation of MANETs. At a given time, not all the nodes can be mobile. A grid of static nodes, which will also support the communication between mobile nodes, may also be considered. In this paper, we analyze the performance of a MANET considering different number of static nodes in the network. For moving nodes we use Random Way-point Mobility (RWM) model. We evaluate the performance by measuring the number of hops and throughput for one-flow traffic. For all topologies, the average throughput is around 5 times lower than CBR of sent data. The number of hops is higher and has more oscillations for denser networks.
