A year-and-a-half ago, we showed you how to turn your $60 router into a highly configurable $600 router with DD-WRT, a free, open source firmware. Since then there's been a lot of development of open source firmwares, and today we're taking a look at my new favorite, a firmware called Tomato. Tomato does almost everything DD-WRT does—from Wi-Fi signal boosting to Quality of Service bandwidth allocation—in addition to offering a simplified interface chock-full of fancy charts and graphs. Sound good? Let's get started.
Researchers in Microsoft Research Redmond, Cambridge, and Silicon Valley are working to create wireless technologies that allow neighbors to connect their home networks together. There are many advantages to enabling such connectivity and forming a community mesh network. For example, when enough neighbors cooperate and forward each others packets, they do not need to individually install an Internet "tap" (gateway) but instead can share faster, cost-effective Internet access via gateways that are distributed in their neighborhood. Packets dynamically find a route, hopping from one neighbor's node to another to reach the Internet through one of these gateways. Another advantage is that neighbors can cooperatively deploy backup technology and never have to worry about losing information due to a catastrophic disk failure. A third advantage is that this technology allows bits created locally to be used locally without having to go through a service provider and the Internet. Neighborhood
