Authentication in Mobile Ad Hoc Network for Secure Communication

For wireless applications the main concern is security. The provisions done for securing the application become bottleneck for widely deployed wireless applications as they affect efficiency. Wireless channels need to be secure. Also it becomes bottleneck because wireless bandwidth is a constrained resource. To achieve security according to the available resource without affecting efficiency is desirable. In particular, mobile adhoc networks (MANETs) based on cooperative communication present significant challenges to security issues, as well as issues of network performance and management. In this paper, we focus on authentication and topology control for mobile ad hoc network. TESLA scheme is proposed to improve the throughput. The scheme proposed works well where no prior information about network is available i.e., for dynamic environment. Results show that our scheme has a capacity to substantially improve throughput in MANETs.
