摘要：Reliability is the important concern in wireless ad hoc networks. Therefore, evaluating reliability has become the essential in MANET. Many existing wireless ad hoc network routing protocols assume the availability of reliable nodes. This, however, is not a realistic assumption given the dynamics of wireless ad hoc networks. Also, due to frequent changes in topology, link failures and node failures are possible. Therefore, a realistic method is needed to evaluate reliability of ad-hoc networks in case of such uncertainties. In this paper, we propose a node failure model, which is injected into the MANET. We then illustrate the effect of node failure on the performance of the mobile ad-hoc networks. This paper evaluates how well a DSR protocols for MANETs behave when under a realistic scenario of momentary node failures and topology changes, which is represented by a node failure model. A gap analysis is then carried out and strategies are planned to improve the performance and reliability of MANET.
