—Energy conservation is essential to wireless networks, particularly for third-generation (3G) and fourth-generation (4G) wireless systems, because high-speed data transmissions would rapidly exhaust the energy of a mobile station. This paper presents the details of energy-saving mechanisms for packet data services in two major standards, namely, the(More)
A synthetic peptide corresponding to the C-terminus of the alpha 3 subunit of the rat neuronal nicotinic acetylcholine receptor (nAChR) was used to generate a rabbit polyclonal alpha 3 antibody. The specificity of this antibody was characterized by immunoblotting, immunohistochemical and immunoprecipitation techniques. Using this antibody, the relative(More)
Neuronal nicotinic acetylcholine receptors (nAChRs) play a significant role in sympathetic transmission in the superior cervical ganglia (SCG), with most of the signal carried by a nAChR containing an alpha3 subunit. Work has shown that transection of the postganglionic nerves (axotomy) of the SCG results in a decrease in mRNA transcripts for alpha3,(More)
To support fast and efficient handovers in mobile WiMAX, we propose fast intra-network and cross-layer handover (FINCH) for intradomain (intra-CSN) mobility management. FINCH is a complementary protocol to mobile IP (MIP), which deals with interdomain (inter-CSN) mobility management in mobile WiMAX. FINCH can reduce not only the handover latency but also(More)
— There are many incompatible wireless systems. How to integrate them has become an important issue. The integration should be done in both Radio Access Networks (RANs) and Core Networks. As that in reconfigurable radio, in this paper we propose a reconfigurable architecture in which different protocols can be used in core networks dynamically. More(More)
SUMMARY IEEE 802.11n could improve the network efficiency of WLAN by aggregating multiple frames into a single transmission. The frame aggregation technique especially benefits multi-hop transmissions that introduce enormous 802.11 medium access control (MAC) layer control overhead. This paper proposes a novel algorithm, namely dynamic aggregation selection(More)

Conventional mesh deployment focuses on the outdoor environment, which regards the WMNs as backbone networks. This study deploys(More)
Keywords: Broadcast algorithm Multi-hop wireless networks Mesh networks 802.11s WMN a b s t r a c t Broadcasting by flooding causes the broadcast storm problem in multi-hop wireless networks. This problem becomes more likely in a wireless mesh network (WMN) because WMNs can bridge wired LANs, increasing broadcast traffic and collision probability. Since the(More)
