Impact of multiple TCP connections in mobile ad-hoc network considering different network sizes

Performance of routing protocols rely on the node mobility, network size, traffic volume, and connectivity patterns. Increasing number of connections in the wireless network creates more data section and incurs more collision. Therefore, there is a need of identifying efficient routing protocol to provide call services in such network. In this paper, we analyze the performance of routing protocols like dynamic source routing (DSR), ad hoc on demand distance vector (AODV) and Destination-Sequenced Distance-Vector (DSDV) for different network sizes creating multiple TCP connections for different mobile nodes considering random way point (RWP) mobility model. Result shows that AODV protocol achieves higher throughput and packet delivery ratio (PDR) at the cost of more packet loss and routing overhead and DSR achieves lower delay as compared to others.
