  • Abstract:  In order to adapt to the time-varying nature of wireless channels, various channel adaptive schemes have been proposed to exploit inherent spatial diversity in wireless ad hoc networks where there are usually alternate forwarding nodes available at a given forwarding node. However, existing schemes along this line are designed based on heuristics, implying room for performance enhancement. Thereby, to seek a theoretical foundation for improving spatial diversity gain, we formulate the selection of the next hop relay as a sequential decision problem and derive a general “Optimal Stopping Relaying (OSR)” framework for designing such spatial-diversity schemes. As a particular example, assuming Rayleigh fading channels, we implement an OSR strategy to optimize information efficiency (IE) in a protocol stack consisting of Greedy Perimeter Stateless Routing (GPSR) and IEEE 802.11 MAC protocols. We present an analysis of the algorithm for a single node. In addition, we perform extensive simulations (using QualNet) to evaluate the end-to-end performance of the proposed forwarding strategy. The results demonstrate the superiority of OSR over other existing schemes.

        • The "My Salvation" Myth
          The "My Salvation" Myth Many believers wrongly think that salvation is a commodity, something that they own, like a ticket to heaven and they think that they cannot lose this ticket. There is no such ticket. Salvation is believing in Jesus, as the Son of God, OBEYING HIS WORDS, accepting Him as your Master and DOING WHAT HE COMMANDED US TO DO. Which is, to repent, turn away from sin, from pleasing yourself and to live in utter obedience to Him, to His words, to be baptized in water, to deny yourself , pick up your cross every day and follow Him; to live to please Him, constantly seeking His approval until the very end of your life. That is salvation. Without Jesus there is no salvation. You need to be pleasing to Him for the rest of your life. It is not a possession, it's a relationship. It's not about reading the Bible, going to church, it is about Jesus KNOWING you and YOU knowing Jesus. Because He will say to many people in that day:"Go away I never knew you!" They never got into that relationship of obedience to Jesus. Salvation is not a possession. It is not something that you can HAVE or LOSE. Either you are obedient and pleasing to Jesus until the very end of your life or you don't have salvation. Salvation is KNOWING the Savior and Him KNOWING YOU, and YOU following Him until the very, very end. May Jesus bless you. www.finalcall07.com From: finalcall07 Views: 0 0 ratings Time: 02:36 More in Education

          Mawaru Penguindrum - Gosh, I Must Destroy Them Soon I made this last night (because I'm awesome like that x3 *jknotreally*) ...nothing special because it was just compiled in a short amount of time...mostly because I'm waiting around for OrgEditor results, and I got bored of playing Arkham City xD This is a little Masako Natsume tribute. I don't have much to say about this other than I'm currently obsessed with this song. *O* I haven't gotten tired of listening to it yet. "Gosh, I must destroy (or crush depending on how it gets translated) her/him/them soon" is Masako's catchphrase in the show. =P Minor characters are awesome (y) & dedicated to camichan19 because she is the only person capable of understanding and actually loving this anime xD In Other News: Results for OrgEditor round #2 are coming out tonight, and I think my entry is fail (so it won't be uploaded to YouTube) but cross your fingers for me because I really do fear that I am in danger of being kicked out this time (even though only three people are going to be eliminated ;_; ugh - the anticipation...)

        • 2012 Toyota Tacoma Base; Toyota of Butte; Butte, Montana
          2012 Toyota Tacoma Base; Toyota of Butte; Butte, Montana www.toyotaofbutte.com Watch out for this one. The 2012 Toyota Tacoma is clearly looking to start something. Like an ATV weekend in the mountains. Or an off-roading trip to the desert. But there's more to this truck than its aggressive new front end. Tacoma is built to finish what it starts. It's forged on massive one-piece frame rails with eight sturdy cross members and a fully boxed front sub-frame. It's got a rugged fiber-reinforced Sheet-Molded Composite bed that provides better impact strength than steel. Plus, a leaf spring suspension with staggered outboard-mounted gas shocks. And an available V6 engine with Variable Valve Timing with intelligence that delivers maximum power on minimum fuel. If you still want to up the ante, it's also got a truckload of extras to choose from: an available TRD Off-Road Package with Bilstein shocks, 16-in. alloy wheels with P265/70R16 BFGoodrich tires, Hill Start Assist Control, Downhill Assist Control and an electronically controlled locking rear differential. So, a word to the wise: Try to stay on Tacoma's good side. Get behind the wheel. The 2012 Toyota Tacoma. Moving Forward. From: ButteToyota Views: 0 0 ratings Time: 02:16 More in Autos & Vehicles

          5 ball routine This is just a little 5 ball routine I was working on today. I got it on video relatively easily (only took one try on this take, after many failed attempts beforehand), and so, naturally, I decided to post it. It goes as follows: From 5b Cascade: A little two up async, into a 3 up cross sync multiplex, into 97531-sloppy (not intended, but these things happen) into halfshower into cascade to a quick transition into 5b shower (someone help me out on that siteswap) into two rounds of hi-low-hi-mid-low or b171d19151 into one round of four layer shower or f1b17131 into shower to a "nifty" transition back to cascade.

SUBSCRIBE to our channel! Thank You! A NEW TRAIN VIDEO every Thursday! CLICK BELOW to read more about this week's railway film! At Venlo there is a lot cross border traffic between Germany and Holland. In this film you see for example a freight train passing Venlo station. It was a very long freight service, almost without end. Usually, we don't show that many freight trains on Railwaylive, so treat this one as an exception and enjoy. Note that the locomotive class 186 belongs to the TRAXX loco family build for both freight and passenger services. They were supposed to be used mostly in Germany, however you will find them in other European countries too. The film was taken on October 13th 2011.

        • Eritean Political Parties & Civil Socities Confrence
          Eritean Political Parties & Civil Socities Confrence Eritrean Education and Publication Trust (EEPT) organised a two-day conference (Mercorios Haile Memorial Conference) on 11 and 12 June 2011 in London. A change in Eritrea is inevitable and the recent developments in North Africa may accelerate it. However, this change could come at a time when there is no harmony between political parties and no functioning constitution. Furthermore, the lack of clarity in the roles of political parties and civil societies are likely to complicate the situation even further. These two concepts are not originally Eritrean. In Eritrea, the confusion between these two sectors may have started when the humanitarian wings (Eritrean Red Cross/Crescent Society and Eritrean Relief Association) were being managed by the Central Committees of the Eritrean Liberation Front (ELF) and the Eritrean Peoples' Liberation Front (EPLF) respectively. This video is a summary of the conference, highlighting the various views of the different political party representatives.
