According to the characteristics of symbols ranging in IEEE 802.16e, a initial ranging detection algorithm which is the combination of time and frequency domain was proposed in this paper. The joint detection of two symbols is adopted to solve the problem of multi-users mobile communication super long coverage caused by phase ambiguity. Simulation results showed that its coverage reached 20 km and...
A mobile ad-hoc network (MANET) is usually power constrained due to the limited battery energy on each node. For MANETS, energy efficiency is crucial for the design of new routing protocols. In this paper, a new energy-aware routing algorithm, called Energy Saving Ad-hoc On-demand Distance Vector (ESAODV) routing, is proposed. In the route discovery process of ESAODV, intermediate nodes estimate the...
Using directional antennas in mobile ad-hoc networks can greatly improve the spatial reuse and the transmission range. However, it also introduces new kinds of problems arising from directivity. One major problem is deafness. In this paper, we propose a new directional MAC protocol with advance notice strategy, called AN-DMAC (Advance Notice Directional MAC). Each node in AN-DMAC maintains a LIT (Local...
