Message Ferrying (MF) is a recently proposed scheme to restore a Mobile Ad Hoc Network (MANET) from partitioning. Despite of the effectiveness in partition restoration, it sometimes suffers from long delay caused by the poor design of ferry route. The Message Ferry Route (MFR) problem has earlier been studied to minimize this drawback of MF schemes. In this paper, we argue that a dynamic way of determining...
The limitation on the battery lifetime has been a critical issue for the advancement of mobile computing. Different types of power-saving techniques have been proposed in various fields. In order to provide feasible energy-conserving mechanisms for the mobile subscriber stations (MSSs), three power-saving types have been proposed for the IEEE 802.16e broadband wireless networks. However, these power-saving...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
