ABSTRACT In this paper, a multilayer security solution is introduced, in order to accord the required end-to-end security blanket to the heterogeneous networks by considering the properties used by authentication at the physical-layer in transport-layer authentica...

Alnumay Affiliation(s) Computer Science Department, King Saud University, Riyadh, KSA . ABSTRACT TCP is a reliable transport protocol designed to perform well in wired networks where packet losses are due congestion. However in wireless ad hoc networks, where packet losses are due to channel errors or link failures between mobile nodes, TCP degrades its performance. Further, it lacks certain protection mechanisms from internal and external malicious nodes. In this paper, a security enhanced and adaptive TCP, namely SA-TCP, has been proposed for wireless ad hoc networks. SA-TCP uses network la...

ABSTRACT This paper presents the evaluation performance of a hybrid satellite constellation network which provides internet access based Transport Control Protocol (TCP). The evaluated satellite network uses the constellation topology operating on Low Earth Orbit (LEO). The COMMStellation TM satellite system implemented using network simulator 2 (N...
