Reliability Analysis of Link Stability in Secured Routing Protocols for MANETs

Abstract

The prime characteristics of Mobile Ad Hoc Network (MANET) are infrastructure free, absence of centralized authority and dynamic nature of nodes which are more vulnerable to security attacks. Reliability and security are prime issues to protect information and nodes in a network during communication which has received more research interest in designing a dynamic secured routing scheme. QoS is set of service requirement that needs to be satisfied by the network during the data transmission in the network. From the perception of QoS best effort protocols ensure optimum network operation in a unpredictable mobile environment. The multimedia applications are intolerable towards delay and reliability which are the features of mobile network, hence the potentials of MANET were not utilized in multimedia applications. These issues of delay and reliability of packet transmission in MANET are contributed by stability of the communication link even during the mobility of the nodes Its a necessity to analyze the performance of various secured routing protocols based on the stability of the communication link in case of mobility of nodes during data transfer. This paper is focused on a comparative study of various secured reactive routing protocols in MANET signifying the connectivity stability during the mobility of the nodes.
