IEEE International Conference on Networks
作者: T. Joshi C. Cordeiro S. Vogety Jun Yin H. Gossain D.P. Agrawal OBR Distributed and Mobile Computing Department of ECECS University of Cincinnati Cincinnati OH USA Networking Technologies Laboratory Nokia Research Center Tampere Finland
In switched single beam directional antenna model, broadcasting is achieved by sequentially steering the antenna beam across all pre-defined directions resulting in a sweeping delay. In this paper, we study the sugges... 详细信息

IEEE Conference on Wireless Communications and Networking
作者: H. Gossain T. Joshi C. Cordeiro D.P. Agrawal OBR Center for Distributed and Mobile Computing Department of ECECS University of Cincinnati Cincinnati OH USA Wireless Communications and Networking Department Philips Research Briarcliff Manor NY USA
In this paper, we propose a directional routing protocol (DRP) for MANETs. DRP is an on-demand directional routing protocol which assumes a cross layer interaction between routing and MAC layer. The main features of D... 详细信息

IEEE International Conference on Communications (ICC)
作者: Younghwan Yoo Sanghyun Ahn D.P. Agrawal OBR Center for Distributed and Mobile Computing Department of ECECS University of Cincinnati Cincinnati OH USA School of Computer Science University of Seoul Seoul South Korea
Routing protocols for mobile ad hoc networks (MANETs) have assumed that all nodes voluntarily participate in forwarding others' packets. This was a reasonable assumption because all nodes in previous MANETs belong... 详细信息
