Performance of Ad-Hoc Network Routing Protocols in Different Network Sizes

Abstract-A Mobile Ad-Hoc Network (MANET) is a temporary network that is composed of the mobile devices which communicates through wireless links without any pre-existing infrastructure. Routing is one of the major concerns in the MANET due to its frequent changing topology and the absence of centralized administrator. In this paper, we evaluate the performance of Mobile Ad-Hoc Network Routing Protocols Dynamic Source Routing (DSR), Ad-Hoc On Demand Distance Vector (AODV) and Destination-Sequenced Distance Vector (DSDV) under different performance metrics like PDF, Average End-to-End delay, NRL, Throughput, Routing Overhead and Packet Loss. The performance evaluation is done in different network sizes using network simulator NS-2. The comparison result shows that AODV gives highest PDF and Throughput, DSR gives lowest packet loss and DSDV gives the lowest NRL, End-to-End Delay and Routing Overhead
