GESJ: Computer Science and Telecommunications 2016|No.1(47) ISSN 1512-1232 64 A COMPARATIVE STUDY OF MAODDP WITH ZRP AND DSR ROUTING PROTOCOLS FOR MOBILE AD-HOC NETWORK Humayun Bakht Research Fellow, London School of Commerce, United Kingdom humayunbakht@yahoo.co.uk Abstract Mobile ad-hoc network offers a unique art of network formation and can be established in the absence of any fixed infrastructure. Due to the absence of centralized supported structure, an ad-hoc network suffers with various challenges. Some of the known challenges to this area include battery power, routing, bandwidth and security. Routing is an integral part of network communication process. It essential stands for route establishment for data transfer among different nodes of the network. Routing schemes for a mobile ad-hoc network can classify into one of many types. With the invention of Mobile Ad-hoc On-Demand Data Delivery Protocol (MAODDP) a new routing family of on-demand data delivery has introduced in the existing portfolio of routing protocols of an ad-hoc network. The contribution of this work is to extend some of the previous work of MAODDP comparison with Zone Routing Protocol (ZRP) and Dynamic source routing protocol(DSR). It was found that MAODDP has several advantages over ZRP and DSR. This work gives an insight into the protocols performance against each other and can be utilized in further extension of the studied schemes. Key Words: MAODDP, ZRP, DSR. 1. Introduction Mobile ad-hoc network is deployed in applications such as disaster recovery and distributed collaborative computing, where routes are mostly multi-hop and network hosts communicate via packet radios [11, 15]. Routing is one of the challenging issues in mobile ad-hoc network. Much effort is under going to invent an efficient routing algorithm for mobile ad-hoc network. Existing protocols for ad-hoc network can generally be categorized into one of many types. In this context on-demand data delivery can be seen as one of the new addition [10]. In the existing literature several studies highlighted relative benefits and benefits of various routing schemes. This paper presents a comparative study of MAODDP with Destination sequence distance vector routing and Ad-hoc on-demand distance vector routing (AODV) protocols. Each of the studies protocol belongs to different family of an-ad-hoc network. This effort is to further explore the basic foundation theme of different families of an ad-hoc network and their benefits. In this context this paper has been organized as follows in section 1 a brief introduction of each of the studied protocol is focused. Section 2. presents a comparative study of MAODDP against Zone Routing Protocol (ZRP) and Dynamic source routing protocol(DSR) and conclusions and future work is presented in section 3. 2. Protocols Studied The following section presents a brief introduction of the protocols being studied and compared. 2.1. Zone Routing Protocol (ZRP) The Zone Routing Protocol (ZRP) is a hybrid routing protocol [1]. It combines both proactive and reactive routing techniques. Each node has a predefined zone centered at itself in terms of number of hops. For nodes within the zone it uses proactive routing protocols to maintain routing information. For those nodes outside of its zone it does not maintain routing information on a
