Comparative Analysis of Numerous Routing Protocols of Mobile Ad Hoc Network

In this paper, we can focus on various routing protocols of mobile adhoc network which are categorized into proactive, reactive and hybrid. These can be further divided into number of protocols. Proactive protocols determine the routing path at the time up of start up and maintain the routing table while Reactive routing protocols determine routing information as and when needed. It means no prior information about routing is collected. Hybrid routing protocols are a newly generated protocols, which are having nature of both proactive and reactive protocols. The hybrid routing protocols employ both reactive and proactive properties by maintaining intra-zone information proactively and inter-zone information reactively. These various protocols are subjected to studies in contrast of time complexity and communication complexity with their compensation and limitations. It was concluded the basic possible concepts on different protocols being used in MANETs. Thus, it was tried to analyze and compare them in accordance with the protocol being used in the network. We have used parameters such packet drop ratio, throughput, latency, applicability, scalability which are used for comparative analysis between various routing protocols. This paper discusses the open research issues on routing protocol of ad hoc network. We have discussed Proactive Protocol (DSDV, WRP, GSR, FSR), Reactive Protocol (AODV, DSR, LMR, LAR) and Hybrid Protocol (ZRP, ZHLS, SLURP, DST). "Paper formatting is very poor" "I have done various changes in the abstract but it is not sufficient, so re correct it because abstract is very important. Do not use the definition of routing protocol in the abstract, write down the name of routing protocol which shows the high performance in the respect of various parameters. " Remove the grammatical and spelling mistakes and increase the number of references. "Do follow the IEEE format" Reduces the number of pages, uses the main heading Abstract, Introduction, Routing protocols, challenges in routing, comparative analysis, conclusion, references. After check the pplagiarism of the paper. It should contain only 20% copy paste data from other resources.
