Abstract: A mobile ad-hoc network (MANET) is a self-organising distributed wireless network without any central infrastructure support wherein every participating node independently acts as a router. Several routing protocols are available for information dissemination in MANETs but their efficiency is limited due to security breaches. Providing security schemes for robust information dissemination is of high prominence for the real time deployment of MANET applications. From the existing literature, it is understood that very few research efforts were made to ensure security for routing protocols and there is a huge scope for the design and development of secured routing protocols for MANETs. In this paper, we have considered the security issues with respect to location aided routing (LAR) and proposed a secured identity-based location aware routing (SIBLAR) protocol to achieve system security with improved key refreshment mechanism. MANET scenarios were created in ns2 and the efficiency of the proposed SIBLAR protocol was evaluated based on certain performance metrics. In the presence of security attacks, the proposed SIBLAR scheme is found efficient when compared to basic LAR.
