A Survey on Routing Protocols and QoS in Mobile Ad Hoc Networks (MANETs)

Abstract

—Mobile Ad hoc network is a wireless communication networkconsistinga number of mobile nodes. The mobile node communicates with each other without centralized control or existing infrastructure. Mobile nodes that are not within the direct transmission require intermediate nodes to transfer the data. Therefore, routing in mobile ad hoc network is a difficult one due to dynamic environment. This paper provides a survey of several routing protocols such as Optimized link state routing (OLSR), Dynamic source routing (DSR), Ad hoc on demand distance vector routing (AODV), Destination sequenced distance-vector routing (DSDV) and Proactive source routing protocol (PSR). This paper gives characteristics, functionality, benefits and limitations of these baseline routing protocols. The performance of these baseline protocols are analyzed by using various network parameters.
