Investigation of the impact of hop-count and node density on MANET´s performance

This paper investigates the impact of the hop-count and node density on the network performance of mobile ad-hoc networks (MANETs). The analysis as well as simulation results indicate that the throughput decreases significantly when the packets traverse over a long chain of hops. Especially when the link is beyond 4 hops, the throughput can only get less than 60% of the single hop throughput. In another observation when node density is increased from 25 nodes to 200 nodes in the area of 500m × 500m, the throughput basically goes down even though it has a bit improvement at small scale of the node density from 25 nodes to 50 nodes.
