An Investigation on the performance evaluation of a scalable and secured routing protocol for mobile ad hoc networks

Abstract

Mobile Ad hoc NETwork (MANET) is a collection of wireless mobile nodes which dynamically form a temporary network, without using any existing network infrastructure or centralized administration. The absence of fixed infrastructure for MANETs causes the nodes to communicate directly with one another in a peer-to-peer fashion. Mobile nodes are no longer just end systems; each node must be able to function as a router, and also must relay packets generated by other nodes. With the ever-increasing acceptance of MANETs in areas like disaster recovery, battlefield scenarios, conference room scenarios, collaborative computing, Vehicular Ad hoc NETworks (VANETs) and many others, the demands placed on these types of networks have massively expanded. A different approach called the location-based (or geographic) routing protocol assumes that each node knows its own location by using the Global Positioning System (GPS) or some other indirect, localization technique. This category of protocols improves the performance of routing and reduces the routing overhead by effectively utilizing the geographical information available. This research work proposes an Improved Location aided Cluster based Routing Protocol (ILCRP). In ILCRP, the network is divided into overlapping or disjoint clusters. The results of the various performance metrics are compared with other existing routing protocols such as Location Aided Cluster Based Energy-efficient Routing (LACBER), Location Aided Routing (LAR) and Cluster Based Routing Protocol (CBRP). Further, ILCRP is analysed for different sets of weights to calculate the Node Value (NV) and to determine the set of weight values that will provide better cluster stability. A network should also be able to protect the routing information as well as data, apart from detection of malicious nodes. This research work provides data integrity through authentication by combining ILCRP-IDS with key management (ILCRP-IDS-KEY). The research work has been extended to implement the proposed ILCRP for VANETs. newline newline
