Time synchronization is an important challenge for femtocell design. An inaccurate clock can introduce interference, degrade spectrum accuracy and disrupt handovers. Among the potential solutions, wireless network-based time synchronization turns out to be cost effective because no extra provisions are required to ensure synchronization even on a regular basis. In wireless networks, receiver-receiver...
The next generation of wireless networks (e.g., Long Term Evolution (LTE)and WiMAX) use multiple techniques to improve channel spectral efficiencies. In this paper we focus on one such technique, namely Coordinated Beam Switching (CBS). With CBS, each sector determines a sequence of beams (possibly with repetitions) over which it continuously cycles. Each sector independently determines its beam pattern...
Time synchronization is critical in distributed wireless networks to achieve and maintain coordination among distributed network nodes. In this paper, we propose a routing based time synchronization protocol (RBTSP) for multi-hop wireless networks. Different from many existing time synchronization protocols, our objective aims at minimizing the number of timing packet exchange and reducing the non-deterministic...
