Abstract

Mobile Ad-hoc Networks (MANETs) can form a network by allowing the wireless nodes without any fixed infrastructure. For MANET’s, early routing protocols are not accounted because of security issues. Further, cryptographic methods were revised to secure the routing information. These protocols had created new avenues for denial of service (DoS) as a part of the process. Thus, the trade-off between security strength and DoS vulnerability has become an emerging area, which required further investigation. Therefore, Different trust methods can be used for the protocol development at various levels during trade-off. To gain the knowledge on this, real world testing which evaluates the cost of existing proposals is mandatory. Without this, the protocol design in the future will be difficult. Thus, in the present paper, the comparison of two MANET routing protocols, namely SAODV and TAODV are carried. This addresses the routing security through cryptographic and trust-based means, and also the performance comparisons on actual resource-limited hardware. Based on this, the design decisions are evaluated for routing protocols in near future. Keywords— ad-hoc, security, routing, trust-based,
