PRoPHET+ computes a deliverability value to determine the routing path for packets. Deliverability is calculated using a weighted function consisting of evaluations of nodes' buffer size, power, location, popularity, and the predictability value from PRoPHET. Even though the proposed PRoPHET+'s weights are chosen based on qualitative considerations, it is possible for PRoPHET+ to perform even more efficiently in various environments by shifting the weights accordingly. Our simulation illustrates that PRoPHET+ can perform better or equal to the routing protocol PRoPHET if logical choices for weights are used.

2006 IEEE International Conference on Communications, 2006

Employing multiple channels is an effective way to improve the performance of wireless networks [... more Employing multiple channels is an effective way to improve the performance of wireless networks [2-10]. Some previous works on multiple channels [2-4] assume at least two transceivers and result in a higher cost on hardware requirements. The protocol in [5] uses a single transceiver and divides the beacon interval into two parts: channel negotiation and data transmission. However, the fixed

A simple two-electrode electrochemical deposition system was applied for the fabrication process. Dense Au nanostructures were grown directly on an Au seeding layer on the substrate. After 48 h, the Au NPs were 2−5 μm in width and 150−200 nm in thickness. The Au NTs were 1−3 μm in height, 300−500 nm in bottom side width, and 20 nm at the apex. The Au NWs were 30−80 nm in diameter and about 20 μm in length. The entire process was template-free and economical. We investigated the correlation between surface plasmon resonance (SPR) and surface enhanced scattering (SERS) effects of the Au nanostructures with different excitation wavelengths. By using the SPR absorption maxima of the nanostructures as the excitation wavelengths for SERS, the highest SERS enhancements were achieved. SERS effects of the Au NWs were investigated further. We discovered that the length and the density of the Au NWs affected the SERS performance significantly. The result is rationalized by the amount of “hot spot” generated at the crossing of the Au NWs. With the Au NWs, Rhodamine 6G can be detected at a concentration as low as 10−9 M.

The nanowires were prepared by reacting HAuCl4aq with Sns in the presence of CTACaq (cetyltrimethylammonium chloride) and NaNO3aq, which were important to the product morphology development. The nanowire diameter was 50-100 nm, and the length was more than 20 microm.

So et al. proposed a multi-channel MAC protocol, which uses a single transceiver and divides the beacon interval into two parts: channel negotiation and data transmission. However, the fixed length of channel negotiation interval limits the channel utilization. We propose
